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.
