This lesson accompanies the BrainPOP topic Perimeter of Polygons, and supports the standard of solving real world and mathematical problems involving perimeters of polygons. Students demonstrate understanding through a variety of projects.

Step 1: ACTIVATE PRIOR KNOWLEDGE

Prompt students to imagine they’re using a map to plan a run. Display this image:

Ask students:

  • How can you calculate the total distance you’d run if you follow the red path? 

Step 2: BUILD KNOWLEDGE

Step 3: APPLY and ASSESS 

Assign Perimeter of Polygons Challenge and Quiz, prompting students to apply essential literacy skills while demonstrating what they learned about this topic.

Step 4: DEEPEN and EXTEND

Students express what they learned about finding the perimeter of polygons while practicing essential literacy skills with one or more of the following activities. Differentiate by assigning ones that meet individual student needs.

  • Make-a-Movie: Produce a tutorial explaining how to determine the perimeter of your classroom.
  • Make-a-Map: Create a concept map sequencing the steps to determine the perimeter of a playground.
  • Creative Coding: Code a math problem about finding the perimeter of a polygon. Challenge a classmate to solve.
