In this activity, students create an image of their own design in a coordinate plane. While determining the ordered pairs needed to make their image, they have opportunities to think about distances in the coordinate plane, signs in ordered pairs, reflections across an axis, and distances from zero. When listing the ordered pairs that make up the vertices of their image, students must attend to precision so that their image can be recreated by another student. 

In the digital version of the activity, students use an applet or other graphing technology to also create an image of their own design in the coordinate plane. The applet allows students to enter ordered pairs and connect points.

The purpose of this discussion is for students to share their thinking about the decisions they made when creating their image. Invite students to share about choices they made when they were determining the ordered pairs for their image. Here are some possible questions for discussion:

• “How did you decide what image to create?”
• “Did you use any symmetry in your image?”
• “How did you incorporate all 4 quadrants?”
• “Did you make any changes to your image after you started?”
• If time allows, consider doing a gallery walk so students can see each other’s designs.
