Tic-Tac-Toe Ordered Pairs

What You Do:

1. Decide which player will use Xs and which player will use Os.
2. Take turns selecting boxes and following the instructions written within them.
3. If a player gives a correct answer, they may claim the box by putting either an X or an O inside of it. For every correct answer, a player also receives 100 points.
4. When a player has attained four boxes in any row, column, or diagonal, they receive an additional 100 points.
5. Play until all of the squares have been claimed. The player with the most points, wins.

Math Review:

When reading an ordered pair (e.g. (-1, -2) ), the x-coordinate is always listed first, and the y-coordinate is always listed second. Find the location of the first number on the x-axis. (In this example, you'll move backward from zero, or the center, one space.) Move up (positive number) or down (negative number) to find the y-coordinate on the grid. Look at the picture on the right to see how we've graphed (-1, -2).
