First Connect Three

This interactive Flash game provides an opportunity for a player to make decisions and develop strategic thinking by analyzing the uncovered number choices on a game board that includes the integers from -5 to 12. Each player rolls the dice, chooses which number to begin with and whether to add or subtract the other number to produce either a negative or positive result shown on the board. The goal is to be first player to complete a row of three counters either horizontally, vertically or diagonally on the game board. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for support, printable instructions and game board, and a link to a more advanced version of the game (Connect Three, cataloged separately).

      Good game

    • This game mixes student choices and the "luck of the dice" well. A nice soft intro to negative integers, sums and differences. Reinforces the commutative property (and its lack in subtraction). Good teacher support here also.
