Stack Dice is one of many dice games for kids. These addition math games are fun because you get to build things. This is a game of addition dice, and it requires quite a few dice. The recommendation is 7 or 8 dice per player. It looks like fun, but by the time I introduced it to my daughter it was too easy for her. You can modify the game by using 10 sided or 20 sided dice to give your child a little bit more of a challenge.
