Math fact challenge

About a month ago I challenged Miss K to learn all her addition facts up to 12 + 12. She was up for the challenge and negotiated a reward as only Miss K can.
I found a folder file/lapbook which she uses to practice with and then I quiz her. When she knows the fact it gets a sticker...not too long now and Miss K will be heading for a tea party in Grapevine. There is a subtraction version waiting for the next challenge.
