I began playing math games with my students using regular decks of cards. However, over the years, I developed my own cards for several important reasons:
Masters for the these special cards can be found on the CD with directions for printing, laminating, and cutting out.
Dice
(random number generators)
All that you will really need are regular dice. They are really cheap and easy to find at stores such as The Dollar Tree, the 99¢ Store, etc. For the most part, you will need two dice. There are a couple of games that require more. One of my favorites is Oops! which requires five dice.
I also like those 1 ½ inch foam dice for younger children. You can get 12 for $4.99 (plus shipping and handling) at the Oriental Trading Company. They make counting the dots much easier.
Some games need parent-made dice. I buy those small wooden cubes from a crafts store or an educational supply store and mark them according to the instructions on the game.
