How to Play 1. Draw a number card from the shuffled stack and turn it face up. 2. Set timer, if using. Have players or teams begin decomposing the number, writing each combination on their paper. 3. W hen time is up, or players have made as many combinations as they can, have players show their decompositions. A point is earned for each correct combination. 4. Repeat the process until all numbers have been decomposed or until time runs out. The player or team with the most points wins. Increase access: Start with the number 5 and give players counting items to help them decompose. Increase challenge: Use larger numbers, negative numbers, or decimals. Total Roll Ideal for children in grades 2 and up who have practiced addition and subtraction. Object Players roll dice and use counting or addition and subtraction to find totals. Encourage players to share their strategies for finding a total. Skill Review Counting on. Begin with the larger of the two numbers shown on the dice (or, if doubles are rolled, count from the number on one die). “Count on” the smaller number from the larger number until you reach the total. For example, if you roll a 2 and 3, count on 2 more from 3 by counting, “4, 5, the total is 5.” Materials Needed • Pair of dice • Paper and pencils for players to record totals How to Play 1. Player or Team A rolls two dice and adds the numbers, recording the sum. 2. Player or Team A can keep rolling as many times as they like. They record the sum each time. 3. B ut, if Player or Team A rolls a 1 on either die, their turn ends, and they lose all points from that turn.
