Solve a Graph Puzzle

What You Need:

• Graph paper
• Pencil
• Ruler

What You Do:

1. Using graph paper, help your child draw a four quadrant plane. Label the x-axis (the horizontal line) and the y-axis (the vertical line). Label the intersecting of both lines 0. Label each point to the right on the x-axis 1 to 7. Label each point to the left on the x-axis -1 to -7. On the y-axis label the points up with positive numbers, 1-7, and then label the points down with negative numbers, -1 to -7. If using the printable Coordinate Plane worksheet, print out and review the x-axis and y-axis
2. Give your child these ordered pairs and ask him to plot them on the coordinate plane:

3. Remind your child to plot the first number of the ordered pair on the x-axis and the second number of the ordered pair on the y-axis.
4. Next, have your child take a ruler and connect the 5 points. Ask him what geometric shape he created (a pentagon).
5. Give your child another set of ordered pairs to graph:

6. Have him connect the 9 points and describe the shape he has created (a tulip)
7. Here's a challenging puzzle for your child to solve. Have him plot this set of ordered pairs:

This time it is important to connect the points in the order shown. If each ordered pair is graphed accurately and each point is connected in the given order, he will have created a five-pointed star!
