My son, Alex is getting his degree in Political Economy, and he gave me the "thumbs up" on Economics in a Box
. It does look like a LOT of reading, so I don't think it would be a good fit if your child doesn't like reading or hates economics. It's also coming from a distinctly free market perspective, which tends to be more conservative. It doesn't include a Biblical component, as well. You might want to look at Jay Richard's book, Money, Greed, and God
, for which Alex earned a mention in the Forward!.
I wrote a blog post on economics for beginners here
Most high school economics classes are 1/2 credit. Since American government is usually 1/2 credit as well, they are sometimes done in the same year. You can do anything you want, but I didn't want you to think economics had to be a whole credit.
