Dice Needed: 6 numbered dice of any combination
(with one die being a unique color)
1. Select the die with the unique color to be the answer die.
2. Roll all the dice.
3. Set the answer die a few inches apart from the others and line up the remaining dice.
4. Add, subtract, multiply, or divide the remaining five dice (in any order) so that the answer
obtained equals the number shown on the answer die. All five remaining dice must be used
in the operations.
5. The first person with a correct solution wins.
Example: Answer die: 5
Remaining dice: 10, 7, 3, 2, 8
Solutions: 8  (10  7) x (3  2) = 5
(8 + 3  10) x (7  2) = 5
(10  3) ÷ 7 + (8 ÷ 2) = 5
