Are your students having problems with money. Here is a center that I have used for two years. Included will be the directions for the game and the game cards. I like to also call this money memory. Basically students will need to find the cards that are a match. A match would consist of the amount and the picture of the coins. I have found this to help them visually see the coins. It is the second best thing to having real coins. You could even send this home with students to play with their parents.
