Connect Three

This problem offers students an opportunity to analyze an interactive Flash game similar to "First Connect Three" (cataloged separately) which involves adding and subtracting positive and negative numbers. This advanced version includes a game board with the integers from -12 to 12. Each player rolls the dice, (one with the numbers 1, 2, 3, −4, −5, −6 and the other with the numbers −1, −2, −3, 4, 5, 6), 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. There a link to a resource, "Playing Connect Three" (cataloged separately).

      Good game

    • After the rules for +/– integers are introduced and practiced, this game puts some strategy and decision making in the students' hands. The applet works well whether playing the computer or a partner. There is some luck involved (the dice) and so it is not too hard to beat the computer. Hooray!
