Title: Grade 3 Mathematics Module 7, Topic E: Problem Solving With Perimeter and Area
URL: https://www.engageny.org/resource/grade-3-mathematics-module-7-topic-e-overview
Description:

In Topic E, students solve problems involving area and perimeter. After an initial lesson problem solving with perimeter, students apply this knowledge to create a robot composed of rectangles. Given specific perimeter measurements, they reason about the different side lengths that may be produced. Students compare and analyze their work, discussing how different choices for side lengths can affect area while conforming to the criteria for perimeter. Students synthesize their learning in the final lessons through solving word problems involving area and perimeter using all four operations.
