This activity is intended to assess your 3rd grade students' ability to find area and perimeter of rectangles and squares. Students will be creating a robot using Google Drawing. They will then find the area and perimeter of each piece of the robot. Once they have found the area and perimeter for each shape in their robot, students will calculate the total area and perimeter of the robot. Photo by Eric Krull on Unsplash
