STL Symphony
During the school year the St. Louis symphony gives an educational series where they invite schools in the area to come and enjoy a symphony that is designed to be good for their age. The programs include good music, an interactive program with the director, and more. I enjoy going to these programs because they are fun and soothing. Several other symphonies across the U.S. and around the world have similar programs. The symphony programs are good for auditory learners.

Duolingo
Auditory and Visual Learners
Duolingo is a free website and app for smart phones to learn other
languages. One of the biggest advantages of Duolingo is that it works
to many learning styles based on the various exercises used to learn a
new language. For each language Duolingo breaks down skill and
lessons in each of those skills.
As part of the skills, the user may repeat a phrase or sentence, type
the English version of the language from a spoken sentence or print of
a sentence, type the language version from a print of a sentence, type
a word based on a picture.
In our house, as English speakers, we are learning Spanish and German.
We have used Rosetta Stone before as well to learn Spanish.
Duolingo is free! It moves much faster than Rosetta Stone so you have
to do your own review. It's very easy to go back to any lesson and
re-do it. Duolingo will have you go back to skills occasionally, but
we have found that we need to review them much more frequently than
suggested.
Duolingo also assigns XP's for each skill that you complete
successfully. For learners that are competitive and are motivated by
earning incentives, Duolingo provides the ability to keep you
motivated.

Pack of Matches
I like to go camping, and here is a quick list of ten things and why to bring them.
TENT
Any will do.
Unless you're a veteran boy scout, chances are
you need some sort of flame to start a fire. Without a fire, you have
limited food options and nights become a whole lot colder. Don't risk
it, and buy matches in bulk. You can leave them in your camping
essentials bag for years at a time.
Rope
Rope has so many uses at a campsite, especially if you can tie a variety of knots. Make a clothes line for wet garments, hang your coolers from a branch at night, create a shelter, or tow people out of a tight situation on a hike or swim. Bottom line: don't go camping without one.Tarps
Whether you're using it to protect the bottom of your tent or as an extra shelter at your campsite, tarps are essential. They're easy to fold, and only take up a small amount of space in your camping bags.A Jar of Peanut Butter
Peanut butter has a long shelf life, and can be used in more ways than you can count. As a versatile source of fat and protein, this should be with you on every camping trip. In a bind, you can schmear it on bread, remove gum from your hair, or just enjoy it in spoonfuls.Portable Spice Rack
You wouldn't dig into an under-seasoned dinner at home, so why would you suffer at the campsite. A plastic, portable spice rack is perfect to throw into your camping essentials bag; most of these are small, easy to pack and hard to break.Lantern, Flashlight or Headlamp
Whether you're stumbling to the bathroom after dark or sneaking a midnight snack, you should always have a lantern and/or flashlight in your camping essentials box. Be sure your light source is easy to reach in the car, in the event that you arrive at your site after dark.Maps and Compass
You have GPS on your phone, and you may even have a GPS system sitting in your car console. Unfortunately, you may not get a signal in remote camping spots, or as you disappear into the forest to go hiking. Have your navigation essentials, such as a map and compass, with you at all times in case your GPS is less than reliable.Alternate Weather Wear
You've checked the weather forecast for weeks—no rain, only sun. Unfortunately, the weather can change at the drop of a dime, leaving you stuck in the rain or huddling around your campfire. With an extra set of clothes, you won't have to worry about sudden weather changes; you can swap out wet clothes for dry ones or layer during a cold front.Pocket Knife
Most commonly known as a Swiss Army Knife, this tool is a camping essential that takes up almost no space in your bags. With a knife, corkscrew, saw, small scissors and more, you'll have a variety of camping essentials in an easy to pack, compact size. You do not need Swiss Army brand. any will do like US Buck, SOG, and Smith and Wesson.Tuesday, November 4, 2014

The Abraham Lincoln Presidential Library and Museum - Springfield, Illinois
This 200,000 square foot complex is designed to impress both the history lover and their tag-along friends or family members. The museum allows you to experience Abraham Lincoln's life from a small boy growing up in his one room cabin reading by the fireplace to his law office and then on through the White House years. Each section of the museum has things to appeal to every type of learner with the interactive displays/videos, written documentation and beautifully designed displays. The 4-D theater is a perfect way to end a fun day at the Lincoln Museum. I would highly recommend this museum to help history come to life.
"George Washington's World" by Genevieve Foster
For students of U.S. History this book is a great read as it tells the exciting story of George Washington from his childhood through his death in 1799. What I enjoyed the most about this book is the way the author told his story while simultaneously explaining other interesting people, events and inventions happening at the same time around the world. I found it very beneficial to see his life in perspective of what was occurring not only in the United States but around the globe. The short sections of this book make it a perfect read-aloud book for a group or family with various aged students.
The Ronald Reagan Presidential Library
I learned so much when I went to this Presidential Library located in Simi Valley, California. My dad and I went there a few years ago and we both really enjoyed it. The museum has self-guided displays suited for everyone. One of my favorites was the Air Force One plane that Ronald Reagan flew in during his presidency which you get to walk through during the tour. Some other highlights include a section of the Berlin wall, some of the Secret Service cars of the time and a Marine One helicopter. The museum not only has a lot of U.S. history it also has shares the details of Ronald Reagan's life from childhood, acting career through his death. This museum is well suited for all types of learners.
Gun Safety
I like guns, but you have to know what your doing. Make sure not to let you children shoot by them selves. If you have more than five guns you probably will want a safe. I think these artikels will help
you shoot safe. Shoot safe, be smart, and know whats behind your target.
you shoot safe. Shoot safe, be smart, and know whats behind your target.
- Don't rely on your gun's safety.
- Be sure of your target and what's beyond it.
- Use proper ammunition.
- If your gun fails to fire when the trigger is pulled, handle with care.
- Always wear eye and ear protechion
- Be sure the barrel is clear of obstructions before shooting.
- Don't alter or modify your gun and have it serviced regularly.

Firearms Safety -- 10 Rules of Safe Gun Handling
1. Always Keep The Muzzle Pointed In A Safe Direction2. Firearms Should Be Unloaded When Not Actually In Use3. Don't Rely On Your Gun's "Safety"4. Be Sure Of Your Target And What's Beyond It5. Use Correct Ammunition6. If Your Gun Fails To Fire When The Trigger Is Pulled, Handle With Care!7. Always Wear Eye And Ear Protection When Shooting8. Be Sure The Barrel Is Clear Of Obstructions Before Shooting9. Don't Alter Or Modify Your Gun, And Have Guns Serviced Regularly10. Learn The Mechanical And Handling Characteristics Of The Firearm You Are Using
NRA Gun Safety Rules
Available as a brochure The fundamental NRA rules for safe gun handling are:
When using or storing a gun, always follow these NRA rules:1. ALWAYS keep the gun pointed in a safe direction.
This is the primary rule of gun safety. A safe direction means that the gun is pointed so that even if it were to go off it would not cause injury or damage. The key to this rule is to control where the muzzle or front end of the barrel is pointed at all times. Common sense dictates the safest direction, depending on different circumstances.2. ALWAYS keep your finger off the trigger until ready to shoot.
When holding a gun, rest your finger on the trigger guard or along the side of the gun. Until you are actually ready to fire, do not touch the trigger.3. ALWAYS keep the gun unloaded until ready to use.
Whenever you pick up a gun, immediately engage the safety device if possible, and, if the gun has a magazine, remove it before opening the action and looking into the chamber(s) which should be clear of ammunition. If you do not know how to open the action or inspect the chamber(s), leave the gun alone and get help from someone who does.
- Know your target and what is beyond.
Be absolutely sure you have identified your target beyond any doubt. Equally important, be aware of the area beyond your target. This means observing your prospective area of fire before you shoot. Never fire in a direction in which there are people or any other potential for mishap. Think first. Shoot second.
- Know how to use the gun safely.
Before handling a gun, learn how it operates. Know its basic parts, how to safely open and close the action and remove any ammunition from the gun or magazine. Remember, a gun's mechanical safety device is never foolproof. Nothing can ever replace safe gun handling.
- Be sure the gun is safe to operate.
Just like other tools, guns need regular maintenance to remain operable. Regular cleaning and proper storage are a part of the gun's general upkeep. If there is any question concerning a gun's ability to function, a knowledgeable gunsmith should look at it.
- Use only the correct ammunition for your gun.
Only BBs, pellets, cartridges or shells designed for a particular gun can be fired safely in that gun. Most guns have the ammunition type stamped on the barrel. Ammunition can be identified by information printed on the box and sometimes stamped on the cartridge. Do not shoot the gun unless you know you have the proper ammunition.
- Wear eye and ear protection as appropriate.
Guns are loud and the noise can cause hearing damage. They can also emit debris and hot gas that could cause eye injury. For these reasons, shooting glasses and hearing protectors should be worn by shooters and spectators.
- Never use alcohol or over-the-counter, prescription or
other drugs before or while shooting.
Alcohol, as well as any other substance likely to impair normal mental or physical bodily functions, must not be used before or while handling or shooting guns.
- Store guns so they are not accessible to unauthorized
persons.
Many factors must be considered when deciding where and how to store guns. A person's particular situation will be a major part of the consideration. Dozens of gun storage devices, as well as locking devices that attach directly to the gun, are available. However, mechanical locking devices, like the mechanical safeties built into guns, can fail and should not be used as a substitute for safe gun handling and the observance of all gun safety rules.
- Be aware that certain types of guns and many shooting
activities require additional safety precautions.
- Cleaning
Regular cleaning is important in order for your gun to operate correctly and safely. Taking proper care of it will also maintain its value and extend its life. Your gun should be cleaned every time that it is used. A gun brought out of prolonged storage should also be cleaned before shooting. Accumulated moisture and dirt, or solidified grease and oil, can prevent the gun from operating properly.
Before cleaning your gun, make absolutely sure that it is unloaded. The gun's action should be open during the cleaning process. Also, be sure that no ammunition is present in the cleaning area.
- Know your target and what is beyond.
1. Always Point a Gun in a Safe Direction.
This one should be self-explanatory. It is the bedrock of all gun safety, and is the most important rule. Another way to say it, which Dad taught me many years ago, is, "Never point a gun at anything you're not willing to shoot."
2. Assume That Any Gun, at Any Time, is Loaded.
When someone tells you a gun is not loaded, that's fine - but don't believe it until you see it for yourself. If you offend your buddy by checking a gun after he's told you it's unloaded, then so be it. Better safe than dead. Make it a habit to check no matter what. This is a very important habit to get into.3. Keep Your Finger off the Trigger.
This is something I see way too often. Some doofus will have his or her finger on the trigger of a gun they are simply carrying, looking down the sights of, etc. Don't do it! Keep that finger outside the trigger guard until you are ready to shoot, and after shooting, move it back out of the trigger guard. And please don't be offended that I used the term "doofus" if you have been guilty of this, because I have been a doofus before, too.4. Know What You're Shooting at.
Your target is whatever you have decided to shoot. And - this is extremely important - it must be a conscious decision when you shoot something. Don't get lax about this. You need to know what you are going to shoot at, what is between you and it, and what is beyond it. Pay attention.5. Be Familiar With Your Gun.
Take the time to learn about the operation and features of the firearm you are planning to use. The time to learn this is not while you are shooting... that is when you need to be learning about grip, shooting positions, trigger control, etc. When you step up to the firing line, you should already know how to operate the gun you'll be shooting.6. Don't Shoot at Hard Surfaces (Including Water).
Water might not seem like a hard surface, but its density makes it pretty dangerous. It has a tendency to allow bullets and shotgun shot to ricochet (glance off) and fly off in an unintended direction. Not good. Hard surfaces like metal, rocks, and hard wood can do this too - and they can even send the projectile back to the shooter, which can be hard on a feller, because shooting oneself, even indirectly, can be a pretty nasty experience.7. Don't Rely on a Safety Mechanism.
Many guns have a safety device to prevent the gun from firing. These are often reliable, but not always. And some guns have even been known to fire when the safety is released, most notably Remington bolt-action centerfire rifles, which naturally leads to the conclusion that safety mechanisms are often useful, but not completely reliable. Use the safety, but don't count on it! Continue to follow the number one rule: Always keep the gun pointed somewhere safe.8. Load Your Gun When You Need to.
Some, including the NRA, will tell you to keep every gun unloaded until you're ready to fire it. This is not a sensible rule, because guns used for hunting and defense purposes will be needed in a hurry whenever they are needed, and there is no time to be messing around loading your gun when you need it to save your life, or to take the game you're hunting. If you need your gun for defense from human or animal attackers and it's not loaded, it becomes a liability rather than a benefit, and your safety goes down the tubes. So load your gun, and handle it responsibly.9. Use the Right Ammo.
Make certain the ammunition you're using is right for your gun. Don't assume that you have the correct ammo just because it can be crammed into the gun. The groceries you feed your firearm need to match up with the gun's design and strength factors. The proper cartridge designation is usually marked on the gun. If you have any doubt, consult the gun's manufacturer or a qualified gunsmith.10. Pay Attention!
It's easy to get distracted when you're having fun, and target shooting can be a lot of fun, especially if you're enjoying it with friends and family. Don't let yourself get carried away. Take extra care to follow safe gun handling rules, and don't be afraid to correct others when you see them improperly handling firearms - we all need a reminder every now and then. Some folks may not like to hear it, but all participants must follow gun safety rules if everyone is to come home safe and sound. And that's what we always want to see!

mandolin playing, by David
My older sister Megan plays the mandolin. When she was starting out, she found three different things that helped her very much. First was, she took lessons from a man named Jerry Rosa. He has a band and company called Rosa Stringworks. Next, she watched videos of other mandolin players to learn from their style. Two of her favorites were Chris Thile and Sierra Hull. Third and most helpful one is playing jams with groups of people. (Jerry Rosa's band and friends play several times a month). She found that playing with other people made her more comfortable and used to playing it. She also got to learn things from the other musicians. Those are the three things that Megan thought were the most helpful. Maybe you can use them if you want to learn to play it too. :)

"The President Has Been Shot": The Assassination of John F. Kennedy by James L. Swanson
This book provides a comprehensive look at the events surrounding President Kennedy's assassination. The author gives you an up close and personal view into the relationships between the President and Mrs. Kennedy and the Secret Service agents while explaining how these relationships impacted the decisions that were made during and immediately following the assassination. At the same time, the author gives you insight into the mixed-up world of Lee Harvey Oswald and his family. He tells each side of the story in a compelling way with narrative, photographs and simple maps. Although the subject matter is heavy, the presentation makes this a great resource. I would highly recommend this book to anyone (young or old) interested in United States Presidential history.

Cavnaugh Flight Museum
Cavanagh is an air museum in Addison (Dallas) Texas. Cavanaugh has a great collection of aircraft including WWI biplanes all the way up to planes and helicopters from Vietnam. Also, the museum has not only American planes but two MiG fighters as well. The museum has tour guides that tell very interesting stories and they offer flights in historic aircraft including a North American P-51 Mustang and Douglas A-1 Skyraiders. this is a great opportunity to learn about historic aircraft. I recommend it for auditory and visual learners.

The World Wars
The Usborne book The World Wars is an introduction and extended overview to the history of Europe, the U.S.A, and Russia from 1914 to 1945 especially around World War 1 and World War 11, this is a recourse targeted toward visual learners but audio and kinesthetic learners will not find this book very useful because it is not a very good read-aloud book, nor does it have any exercises to do. I like this book because it provides information on different occurrences in a period that I like to study.

For a great video watch this one!
Small gas engines serve us in many
ways. They power lawn mowers, tillers, cultivators, trimmers, edgers,
snow blowers, chain saws, pumps, generators, air compressors, and other useful
home tools. They also power our fun: outboard boats, snowmobiles, motorcycles,
all-terrain vehicles, ultralight aircraft, and other toys. To keep them
operating efficiently, an owner of these tools and toys should know about small
engines: how they work and what to do when they don't.
Small gas engines are made up of
individual systems that work together to produce power. Each system has many
components. Internal combustion gasoline-powered engines require six systems:
fuel, exhaust, ignition, combustion, cooling, and lubrication. In this article,
we will discuss the systems and components that make small engines work.
Fuel and Exhaust
The fuel and exhaust systems are
critical to operation. They furnish the fuel for combustion and remove exhaust
gases. The following are components of a fuel and exhaust system.
Gasoline: Gasoline is a combustible liquid that burns relatively
slowly. However, when sprayed as a mist and mixed with air, it is quite
explosive. All it needs is a spark. Two-stroke engines require that oil be mixed
with the gasoline to lubricate internal parts. Four-stroke engines use a
fuel-air mixture.
Fuel Tank: The fuel tank stores fuel in preparation for mixing by the
carburetor and use by the engine. Some fuel tanks are pressurized with air to
help deliver fuel to the carburetor. Other tanks are non-pressurized and depend
on a fuel pump to deliver fuel to the carburetor.
Fuel Line: Fuel is moved from the tank to the pump and/or carburetor
through a fuel line. Pressurized fuel systems often have a squeeze bulb in the
fuel line for building pressure.
Filter: A carburetor jet has a small opening that can easily become
clogged. A fuel filter traps dirt and sediment from the gas before it is
delivered to the carburetor.
Pump: A fuel pump produces a vacuum that pulls the fuel from an
unpressurized tank, then delivers it to the carburetor.
Carburetor: The carburetor has one job: to mix the correct proportion
of gasoline and air for the engine. Too much gasoline in the mixture makes it
rich; too little gas makes it lean.
Throttle: The throttle controls the amount of fuel-air mixture that
enters the engine from the carburetor. The throttle thus controls the speed of
the engine.
Primer: A primer injects a small amount of gasoline into the
carburetor throat to make the initial fuel-air mixture rich. A primer is used
to help start a cold engine.
Choke: Some engines control the richness of the fuel-air mixture
at startup by controlling the air rather than the fuel. A choke reduces the
amount of air in the fuel-air mixture.
Governor: A governor is a device that automatically opens the
engine's throttle when more power is needed and closes it when the load is
light.
Muffler: Small gas engines, especially two-stroke engines, are noisy
when they operate. A muffler reduces the sound of the exhaust gases by passing
them through baffles.
Spark Arrestor: A spark can exit the exhaust port of a small gas engine,
potentially starting a fire on nearby combustibles. A spark arrestor on the
exhaust port can reduce the chances of such a fire. Spark arrestors are
especially important on chain saws, motorcycles, and all-terrain vehicles
operated in dry woodlands.
Ignition
The ignition is a primary system
within all small gas engines. It produces and delivers the high-voltage spark
that ignites the fuel-air mixture to cause combustion. No spark means no
combustion, which means your engine doesn't run. Below are the components found
in small engine ignition systems. Some systems will include breaker point
ignitions while others depend on solid-state ignitions.
Magneto-Powered Ignition System: A magneto uses magnetism to supply electricity in ignitions
where there is no battery. The magneto is turned by the crankshaft, which
rotates when the manual recoil starter is pulled. The three types of magneto
ignition systems are mechanical-breaker, capacitor-discharge, and
transistor-controlled.
Battery-Powered Ignition System: If your small engine includes a battery for starting, the
ignition coil will also use it to supply spark to the spark plugs. A battery
stores electrical energy until needed. Battery ignition systems also use
mechanical-breaker, capacitor-discharge, and transistor-controlled ignitions.
Mechanical-Breaker Ignitions: High-voltage electricity must be sent to the spark plug at
the appropriate time. In mechanical-breaker ignitions, this job is performed
through the contact points and a condenser.
Points: As the crankshaft rotates, a cam opens and closes a set of
contact points. These points function as an on/off switch: Closed is on, and
open is off.
Condenser: Because the spark moving across points can damage their
surfaces, the condenser stores voltage to reduce arcing between points.
Capacitor-Discharge Ignitions (CDI): A capacitor is a large condenser. A CDI stores and delivers
voltage to the coil using magnets, diodes, and a capacitor
Transistor-Controlled Ignitions
(TCI): Transistors are electronic
controllers. A TCI uses transistors, resistors, and diodes to control the
timing of the spark.
Coil: An ignition coil is simply two coils of wire wrapped around
an iron core. The coil changes low voltage (6 or 12 volts) into the high
voltage (15,000 to 30,000 volts) needed by the spark plug.
Spark Plug: A spark plug is an insulated electrode that is screwed into
the top of the engine cylinder. High-voltage timed electricity from the magneto
travels by wire to the spark plug. The base of the plug has an air gap of about
0.030 inch (30 thousandths of an inch), which the current must jump.
Wires: The primary wire from the coil to the breaker point and
secondary wire from the coil to the spark plug(s) deliver electricity to the
ignition components.
Distributor: A distributor is an ignition system for engines with more
than one cylinder and spark plug. It distributes the spark to the appropriate
cylinder using a rotor, cap, and individual spark plug wires.
Combustion
The combustion system of a small gas
engine is where the work gets done. Components of the combustion system include
the cylinder block, cylinder head, camshaft, valves, piston, connecting rod,
crankshaft, timing gears, and flywheel. To better understand small gas engines,
let's look at how this vital system works.
Cylinder Block: The largest single part in a small gas engine is the
cylinder block. It is a piece of metal in which the cylinder hole is bored or
placed.
Cylinder Head: The cylinder head is the top, or ceiling, of the cylinder
and is attached to the block with bolts. Depending on the type of engine, the
head may or may not include valves.
Piston: A piston is the movable floor in the combustion chamber.
Its upward movement compresses the fuel-air mixture. After combustion, its
downward movement rotates the crankshaft.
Crankshaft: An engine's crankshaft is a metal shaft with an offset
section onto which the connecting rod is attached. Rotation of the crankshaft
moves the piston up in the cylinder. Movement of the piston down in the
cylinder then rotates the crankshaft.
Connecting Rod: Between the piston and the crankshaft is a connecting rod.
At the larger end of the connecting rod is a bearing that allows rotation
around the moving crankshaft. The small end is attached to the piston pin.
Valves: Valves simply open and close passages. A reed valve in a
two-stroke engine is activated by changes in air pressure.
Flywheel: At the end of the crankshaft is a circular weighted wheel
called a flywheel. The flywheel delivers the engine's power to devices (wheels,
blades, etc.) and helps keep the crankshaft turning smoothly.

©2006 Publications International,
Ltd. Here are some of the components of a two-stroke engine's combustion
system. See more pictures of small engines.
Cooling and Lubrication
Combustion and friction produce
heat. Heat and friction -- if not controlled -- can quickly damage an engine's
components. Small gas engines are typically cooled by air. Friction is reduced
using movable bearings and lubricants.
Air-Cooling Fins: For simplicity, most smaller gas engines are cooled by air.
Metal fins around the outside of the combustion chamber help dissipate the
internal heat.
Friction: Friction is resistance that occurs when one surface rubs
against another. Friction causes wear. In an engine with many moving parts,
friction is reduced with bearings and lubricants.
Bearings: A bearing is a replaceable part that takes the brunt of the
friction. A friction bearing relies on lubricants to minimize friction. A
nonfriction bearing uses hard steel rollers or balls to prevent wear, though it
too requires some lubrication.
Lubricants: Lubricants such as oil and grease reduce surface friction
by coating parts with a film. Lubricants in two-stroke engines are applied to
surfaces by mixing oil with fuel.
Viscosity: An oil's viscosity is its resistance to flow. The thicker a
lubricating oil or grease is, the higher its viscosity number.
Filters: Friction happens. Moving parts wear, even with the best
lubricants. The resulting metal as well as carbon from the combustion process
must be cleaned from the oil to ensure long lubrication. Some small engines use
oil filters to remove contaminants from the circulating oil.
Regularly servicing your small
engine will ultimately save you money and time. In the next section, we'll
review how, where, and when to service this engine

I like math and I use Life of Fred
Life of Fred is a series of text boot series that takes you though elementary school to collage. I have done the elementary series and have started the before high school series. The books are a story of a 5-6 year-old boy named Fred and his life as a math teacher at KITTENS collage the first part of every chapter is a story about Fred and his life as a teacher and at the end of each chapter it has a "Your turn to play" in witch you do your part and answer questions about stuff you learn in the chapter about math and sometimes other things. I am currently in the elementary physics book and am laughing and working through the book.
I like math and I use a website called Khan Academy
Khan academy is a mastery learning website where you can learn anything from counting to calculus. I use Khan Academy for my school math and sometimes just for fun. Mostly I use Khan Academy for forth through seventh grades, I find that Khan Academy helps me learn the math that I like at my own pace.
there are two types of tasks. Practice: this is where you start to learn a skill, usually you have to get five to three problems in that skill correct in a row to get it practiced, if you don't know how to do that skill you can usually watch a video that will teach you how to do the skill. Mastery challenge: here you can master the skills you have already practiced by answering a problem in that skill.
There are five levels from practiced to mastered that are: Not practiced, Practiced, Level 1, Level 2, and Mastered.

Kahn Academy
Kahn Academy is a website that uses mastery learning to help people of all learning types learn math, history, Java script, science, and test prep. Kahn academy can be used without an account but is much better with. I like Kahn academy because it is easy to learn on there, the website will ask you a series of questions that if you answer correctly you upgrade that skill to the next level and eventually mastery. Later on it will test you on that skill and possibly downgrade it so that you have to re-master it. In other courses you watch a series of videos and then take a quiz to see if you learned anything. I like to do the math and am trying to master 7th grade as well as doing history after 1700, the SAT test prep is good as well. I recommend Kahn Academy to visual and audio learners because of the videos and to kinesthetic learners for the exercises.
