I really liked the thinking maps on there, Bruce. Mindmap configurations for different types of problem solving are given, and I think that would be a useful thing to try out.
I've found the coolest parenting site:
DadCanDo
It's geared toward Dads, particularly weekend dads and single parents, but any parent and kid can use it. It's got soooo cool projects, like making a Harry Potter wand with paper and a glue gun; templates for building models of things like the TARDIS; Toys From Junk, and lots of other, very clever, ideas.
