I really, really liked BJU consumer math but with a couple caveats:
- they used a lot of formulas such as interest etc and had continuous review of them throughout the book (which was great) but the formulas were never listed in one location and are definitely complicated enough that you would never memorize them all. After getting into the book for a little while we started writing them on a separate sheet and that really helped.
- Some of the lessons had a ridiculous amount of problems. 15 problems of the same easy step over and over or towards the end having to do 10 different tax returns in one lesson. You just need to be comfortable saying 3 of those or 2 of those.
Loved the overall topics and presentation, the review of lots of basic math, and layout (except for the lack of one spot the formulas are listed).
We did the Dave Ramsey (personal finance wisdom) at the same time and plan on doing economics (the laws of economics and the whole government policy) and accounting (business end of things) next year. They all cover different things but for a child who is interested in entrepreneurship I think the combo is important and not too repetitive.
