```Graphing GameLalagos, Thomas           Hyde Park Career Academy                          947-7180                           Objective:

To introduce the graphing of ordered pairs on the cartesian plane.

Materials:

A cartesian graph that goes from -4 to 4 on both axes.  The axes should
be thick lines with arrows facing in the positive direction.  The other lines on the graph should be lighter than the axes.  Horizontal lines should be a different color than the vertical lines, but it is not necessary.  Do not label anything.  No X-axis, no Y-axis, no numbers on the axes. Strategy:

Divide the class in teams (if possible no more than 4 teams with no
more than 7 students per team).  Assuming that you have 4 teams, take 4
sheets of paper write the group symbol assigned to each team on top of
their paper and ask them to list the names of their team on that
paper.  You may want to use X, O, /\, #, for the four different symbols.  After the students have written their names on their team paper, collect the papers, write the 4 symbols on the board and list the members of each team under their symbol.  Leave enough space between the team columns on the board so that you can insert checks to keep track of who is up next when you play the game.  Directions to
students: The object of this game is to get four of your symbols in a row, (next to each other) horizontally, vertically, or diagonally.  At the same time you may wish to prevent the other teams from getting four of their symbols in a row.  All teams start off with 20 points. When a team gets four in a row, 4 points are added to its score, but the other three teams get one point subtracted from their score.  To get your symbol on the graph choose a pair of numbers from the set that is on the board {-4,-3,-2,-1, 0, 1, 2, 3, 4, }. You may use any pair of numbers from this set including using the same number twice. Once I call on you and you give me a pair of numbers, you must watch
how I move on the graph.  I will not explain.   Once you give me both numbers of the pair you cannot change your mind, but it's O.K. to change your mind after saying the first number.  If the point described by the pair of numbers that you give me is already occupied, you lose your turn.  Remember, the pair of numbers that you give me are directions on how to move and I will follow those directions.  Team members may help each other, but only the person that I call on can give me the pair of numbers.  You cannot tell another team what to do. Teams and/or individuals will have points taken off if they don't play by the rules.  Further directions to the teacher: Put a check on the board after the student's name once they have taken their turn.  Since the number of students on each team will not always be the same, it will help you keep track of who is next on that team when it is that team's turn to play again.  Two possible ways to end the game:  A) Once a team has four symbols in a row erase everything and start     over.                        B) Once a team has 4 symbols in a row erase only those four symbols    and continue playing the game.Either way the game will end when the bell rings.There are several variations of this game and you may wish to develop your own.```
