The First Grade Sweet Life: Reading Centers--pattern block sight words! Get some templates, write words on them, and the kids have to play in pairs--correctly saying each word (and using it in a sentence?) before they can cover it. Also for math shapes!
Short vowels: Shake it short vowel sounds song. Its a great way to get those kinesthetic learners learning and moving. While students sing the song, they shake the body part that goes with the vowel. There are also pictures included for visual learners.
