The idea behind Life of Fred is that if students have an enjoyable experience and have fun doing their math, they will remember it and use it and have a good taste in their math about the whole subject. The sub-title on each of his math books is "As Serious As it Needs to Be". And that is just the point: math doesn't need to be horrid and dry. This is math-just as serious as it needs to be-and I can tell you from my child's smiles and chuckles, that's not very serious at all! As a bonus, these books are very low priced compared to any other math books on the market. (Compare to Saxon at $50-70). If you have a creative child who is languishing on traditional math programs, try Life of Fred! Math, As Serious As it Needs to Be!
