What a great thread!!!!
I wanted to add another one I just thought of:
http://www.starfall.com/
They have lots of free downloads for helping children read/write, and very cool, fun notebooks/workbooks that they sent us for free a few years ago...looks like they may charge a small fee for them now....less than two dollars! Definitely worth it!!! We have the Level One Reading and Writing Journal (block print) and the Cut-Up Books that include learning about great art masters like Van Gogh....absolutely wonderful stuff!
Looks like you can also download these things to print from your computer at no charge!
