Playing the Fact Power Game 2 players, or small groups For each new game, use the game mat of one of the players. Directions: Players place their markers on START. They take turns rolling a die and moving their markers the correct number of spaces across the rows, as indicated by the arrows on the game mat. When a player lands on a space, he or she says the sum. The others check that the sum is correct. If correct, the player marks the space with his or her initials. If a player lands on a marked space, he or she moves to the next open space. A round is over when a player reaches or passes END. At that point, there will be some spaces marked and some not. Players then start again at the beginning. When time is up or all of the spaces have been marked, players count their marked spaces. The player with the greatest number of marked spaces wins the game. http://everydaymath.uchicago.edu/educators/em_games

Exploration B: Practicing Addition Using egg cartons as random number generators, partners add two numbers, record sums on their slates, and tally the number of odd and even sums. 1. Partners take turns shaking two small objects inside an egg carton. 2. They open the carton and note where the objects have landed. 3. Using the numbers as addends, children write the sums. 4. They keep a tally of how many odd sums and how many even sums they generate. even odd
