I have been checking out some links I found to teacher websites and I came upon this one http://schoolexpress.com/fws/cat.php?id=2801 It appears to be unit studies for all 50 states. It would go good with the state book that was on here. This site has thousands of worksheets, I am still digging around looking at all of this stuff.
Wow--those are awesome. Dd 6 is wanting to learn more about the states, so I just may have to do those with her this year!
