We love (in no particular order):
A brief word about the sidewalk chalk: We sometimes just draw fun pictures and do hopscotch, but I really like it for the educational opportunities it provides. At our house, we use it to work on our weekly Bible memory verse. I write it with the chalk, and we jump on the words as we say the verse. I can jump on the right words as I say them, but the younger kids just jump everywhere. That's fine because they are still saying the verse! For review, I can also just write a bunch of random letters and either call out the letter or the sound it makes, and have the kids hop to whichever I call. Fun!
