Grade Levels: 3-5, K-3

In this lesson plan, which is adaptable for grades 3-5, students use BrainPOP resources to learn to how to calculate the area of rectangles. Students will then make a real-world connection and show their understanding of finding area in differentiated activities including BrainPOP’s Make-A-Map tool.

Students will:

  1. Students will be able to use a formula to find the area of a rectangle.
  2. Students will apply their knowledge of finding area to a real-world situation.


  • Computers with internet access for BrainPOP and an interactive whiteboard


Area Multiply Length Width Square Units


Students should have an understanding of how to use the Make-A-Map tool

Lesson Procedure:

  1. At the start of a lesson, ask students: If we needed to buy tiles to cover the floor of our classroom, how would we need the amount to buy? What about wallpaper for the wall?
  2. Pre-teach key vocabulary words by using the Area of Rectangles. Pose the following focus question before watching the video: Why do we need to know how to find area?
  3. After playing the video, discuss why Ben and Moby need to find area and the steps they took to find it.
  4. To show their understanding, students have a choice to different activities base on various learning styles. Students can write a "How To" guide for finding the area of wall with a door. After describing the steps, students will need to create their own wallpaper scenario and solve it. Or, students can Make-a-Map and explain how to find area of a rectangle by inserting a video clip and explaining it. Then, they will explain how the area is changed if this rectangle was a wall with a door. Students will need to create their own wallpaper scenario and solve it.
  5. Have students share their work with each other.
