I'm not sure if public schools had book fairs and a bookmobile, but the school district I grew up in did. Presumably because the school got a cut of the sales, and it's hard to argue getting kids to read. I can't remember the book for the life of me, but I had something that explained much of home economics and some very basic economics concepts at a 3rd or 4th grade level, rife with illustrations. There's still books available such as "The Everything Kids' Money Book" and whatnot. One would assume they're written to be engaging to at least some portion of kids.
