What is Life of Fred? I poked around and the books on amazon had good reviews.
Math taught through the adventures of a highly gifted little boy (6 years old?) who is a professor at Kittens University.
The first dozen times I saw LoF mentioned on a forum I thought it was a joke. But eventually I bought a few books out of curiosity, which my oldest son has read and re-read. I guess a "spoonful of sugar" works. The other day he was reading LoF and then demonstrated how to solve 2x2 linear equations using Cramer's Rule. We don't use LoF as primary textbooks.
