Recognizing Patterns on a Coordinate Plane

This lesson teaches students how to recognize patterns by graphing ordered pairs on a coordinate plane. It begins with a review of graphing techniques and then presents a problem involving movie ticket prices. Students learn to calculate the cost of tickets and graph these costs as ordered pairs. The lesson concludes by identifying patterns in the graph and addressing common misunderstandings about the x and y axes.

What is the first step in solving the problem about movie ticket prices?

How did Reggie and Cady's ticket purchases help determine the cost of one ticket?

Explain how to create a two-column chart for the movie ticket problem.

What pattern do you observe when graphing the ordered pairs of ticket prices?

Describe the relationship between the number of tickets bought and the total cost.

What mistake do students commonly make regarding the x-axis and y-axis?

How can you remember the order of the x-axis and y-axis when graphing?
