I've been inspired by Jimmie at Jimmie's Collage to play more math games and not be such a freak about completing all of those work sheets. We decided to play multiplication war.
She's only worked on multiplication up to 5, so I made my own die with numbers 0-5. Each time we lay down a card, we roll the die and multiply to get our answer. Our answers then go to "war" with each other. She's had lots of fun and has painlessly studied her facts for over an hour (these games can go on forrreevveerrr!)
