Detailed Product Description

A twelve-sided die with the numerals 1-12.

Ideas for Use

Easy Class Review--Substitute for Flash Card Drill

Divide the class into groups. Give each group a pair of numbered dice. Have them roll the dice and practice one of the operations as many times as possible until time is called. This can be made harder or easier by the dice selected.

Brain Bender

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

Game Board Upgrade

Dice needed: 2 numbered dice
Other equipment: game board and movers

1. Select one die to be the movement die. Decide whether the dice will be added, subtracted, multiplied, or divided.
2. Roll the dice and state the correct problem and answer. Then, move the number shown on the movement die.
3. If the problem or answer is incorrect, the turn is forfeited.
4. Other rules may apply depending upon the board game used.

Example: A red and a blue dice are rolled. The
red die is the movement die.
Roll: 3(r), 5(b)
Addition: Say “3+5=8” or “5+3=8”
and move 3.
Subtraction: Say “5-3=2” or “8-3=5”
and move 3.
Multiplication: Say “3x5=15” or
“5x3=15” and move 3.
Division: Say “15÷3=5” or “15÷5=3”
or “5÷3=1 with a remainder of 2”
and move 3.

Other equipment: pencil and paper for score keeping

4. The first person to twenty wins.
