Coco's 4th Grade Curriculum- Social Studies

My friend Sherri and I were on the phone and it came to me... Instead of just doing US History, why couldn't we do Explorers?!! I started on www.enchantedlearning.com and went through their list of explorers (that comes with at least one worksheet per explorer and a printable bio)

We are definitely looking for any resources we can get on this one.

38) Final Review and testing.

I have created a lapbook style worksheet for this so she will have a Bio on Mondays, a worksheet from enchantedlearning, a worksheet from me, a vocab sheet with a crossword or word scramble (Gotta love www.theteacherscorner.net) and we have lots and lots of maps that I also got from enchantedlearnig.
Typically we test every 10 weeks and I have made those too.

Does anyone have any ideas or suggestions? (or materials I can borrow?)
