problem_activity: Narrative
The purpose of this activity is for students to identify and name shapes in the environment. The shape walk can take place in the playground, library, or another area of the school. It may be easier for students to use their recording sheet if it is on a clipboard.
When students recognize mathematical features of objects in the real world, they model with mathematics (MP4).
Engagement: Develop Effort and Persistence.
Students may benefit from chunking this task into smaller parts. Invite students to look for one shape at a time. Check in with students to provide feedback and encouragement after recording each shape.

“We are going to take a walk around the playground. Look for examples of triangles, rectangles, and circles around the playground. Tell your partner about the shapes you find and draw pictures or write words to record what you find.”
Activity
10 minutes: shape walk
“Write a number to show how many of each shape you found.”

“Han found this swing on the playground. Where should he draw this on the recording sheet?” (The swing looks like a rectangle so he could draw it with the rectangles. The sides of the swing look like triangles.)
