Lesson 19Drawing on a Coordinate Plane

Learning Goal

Let’s draw on the coordinate plane.

Learning Targets

I can use ordered pairs to draw a picture.

Activity 1: Cat Pictures

Problem 1

Use graphing technology to recreate this image. If graphing technology is not available, list the ordered pairs that make up this image. Then compare your list with a partner.

A picture of a cat face on a coordinate grid drawn only with straight lines.

Problem 2

If you have time, consider adding more details to your image such as whiskers, the inside of the ears, a bow, or a body.

Are you ready for more?

If you are using graphing technology, add these statements to the list of things being graphed:

$x > 6$
$y > 5$
$x < - 4$
$y < - 6$

Describe the result. Why do you think that happened?

Activity 2: Design Your Own Image

Use graphing technology to create an image of your own design. You could draw a different animal, a vehicle, a building, or something else. Make sure your image includes at least 4 points in each quadrant of the coordinate plane.

If graphing technology is not available, create your image on graph paper, and then list the ordered pairs that make up your image. Trade lists with a partner but do not show them your image. Graph your partner’s ordered pairs and see if your images match.
