Plotting on a plane coordinate system is an important prerequisite to graphing algebraic equations. Help your fourth grader better understand this concept by playing a game of Tic-Tac-Toe! Take turns rolling dice and creating coordinates. The first player to claim three coordinates in a row, wins! Use important vocabulary terms while playing, such as "x-axis," "y-axis," and "coordinates" in order to help reinforce these concepts.
Terms to Know:
x-axis: the horizontal axis in a plane coordinate system
y-axis: the vertical axis in a plane coordinate system
What You Need:
What You Do:
- Each player selects a simple shape (e.g. square, circle, triangle) they will use to mark their locations on the grid.
- Players take turns rolling the dice, then translating the dice into ordered pairs. For example, if a player rolled a 3 and a 5, they could create the ordered pair ( 3 , 5 ) or ( 5 , 3 ).
- Players plot their coordinates on the grid, using their selected shapes to claim each location. Only one player may claim each location.
- A player wins when they have claimed three coordinates in any row, column, or diagonal.
Use custom dice and/or a different grid.
Remember, when reading an ordered pair, the x-coordinate always comes first. In the example
( 5 , 3 ), the x-coordinate is 5. Find this by moving along the x-axis to where "5" is marked. Then move up 3 spaces to find the y-coordinate. In the picture shown, ( 5 , 3 ) is marked with a circle.
