Teaching Math Counts ~ Trenton ~ 2005-2006 Quest Home | Trenton Home | The Math Forum @ Drexel Games for Developing Computational Fluency But Who’s Adding? A game for two players or teams. Click here to download a pdf game board. Each player/team needs nine chips of one color. Object of the game: to get four of your chips in a row, horizontally, vertically, or diagonally. Player A places a chip on a number circle at the bottom. Player B puts a chip on another number circle at the bottom, adds the two circle numbers, and places a new chip on the square on the grid that contains the sum. From then on each player in turn moves her/his circle number chip to a new circle and places a new chip on the sum on the grid. A player may only cover a circle number if the corresponding sum is available on the grid. Play continues until one player gets four in a row, or there is no move left. A player may place a chip on top of another player's chip to make a sum in the square. There can only two two chips at the bottom at any time. Face the Facts A game for four players You need a standard deck of playing cards with Jokers and face cards removed. Players A and B sit facing each other. Each has half the deck. A third person, the Caller, sits to the side facing the middle. When this person says "Go," the two players with the cards each take the top card with out looking at it, and place it on their own foreheads so that the others can see it. The Caller says "The sum is ___." (or product) Players A and B each try to figure out the number they are holding. The player who correctly names their own addend/factor first gets to keep both cards and add them to the bottom of the deck. A fourth player, the Checker, has a calculator to check the sums/products. After a specified amount of time, the person with the most cards wins. Ace cards have a value of one. Destination Zero A game for 2 to 5 players, or teams You need a set of dominoes, scratch paper and pencil Object: To reach a number as close to zero as possible without going below it. Spread dominoes face down on the table. Each team chooses any 5 of the unexposed dominoes. They should be aligned vertically, face down. Each team begins a round with 100 points. Each team must use 4 of the 5 dominoes. One of the pieces becomes an optional domino. Players take turns exposing one domino at a time. The domino at the right may be used as either 34 or 43, or discarded. Players subtract the selected value from 100, or from the previous remainder. Play continues until each player has use at least four of the five dominoes. The winner is the player whose remainder is closest to zero without going below.
