The idea I shared was a game called Heads and Tails Shake. I am sharing it with you and a recording sheet that I made. It's not terribly pretty so if anyone else can "spif it up," feel free. Just make sure you send me a copy.
I can't remember where I learned to play this game but I've used it for the last four years. I just made up a recording sheet to go with the game to check for understanding. I hope it is something that you can use.
Be sure to check out Lory's Page. She has some great ideas.
