What level of material does your child seem ready to handle? Middle school textbooks very colorful nowadays, and if your child isn't ready to read them by themselves, I think that they would make good jumping off points for discussion. My son had one in 6th grade about ancient civilizations that he would have loved as a 2nd grader. DK publishes mini-encyclopedias that are also very good.

Best Wishes,
