Zero to Ninety-Nine

Mental math has never been more exciting! Practice adding and subtracting as a group. Help each other keep track of the running total as the game progresses. Roll the die, and wish for the best. Use a little bit of strategy to help control this game of chance, and you could come out the winner.

What You Need:

• Two standard dice (Make your own.)
• Scratch paper and pencil (optional)

What You Do:

1. Start with a running total of zero.
2. Players take turns rolling the dice and adding their score to the running total. The goal is to not go over 99. Players are able to control the game when they roll a 9 or a 10. A score of 9 or 10 may be added or subtracted, and it's up to the player who rolls it what operation will be used.
3. The player who causes the score to go over 99 has lost.

Variations:

• Use a different goal and starting value. For example, start at 1895 and stop at 2000.
• Use customized dice. (Print out a template.)
• Use a calculator. This allows you to focus on the skill and not the computation.
