Add-em Up
Materials: 2 players, 2 dice, counters and a game board for each pair of students.
Players place the counters below each number. Player #1 rolls the dice and adds the 2 numbers. He/she removes the counter that is under that sum.
Example: Player #1 rolls a 3 and a 4. He/she removes the counters under the 7.
Players take turns rolling the dice and removing counters. When a player cannot remove counters that match the sum they lose that turn. Play until neither player can remove counters. The player with the most counters removed wins.
Subtraction
*Use a 12 sided dice. Players roll the dice and subtract the 2 numbers rolled. He/she removes the counter that is under that difference.
Probability
Players get 11 counters and can place them anywhere on their board. The players then play either add/sub game removing the counters under the numbers as they play.
Example: Player #1 places 3 counters under 7, 4 counters under 6, and 2 counters under 3 and 2 counters under 8.
They will soon see that 5, 6, 7, and 8 are rolled more often than the other sums.
