Title: Grade 4 Mathematics Module 3, Topic A: Multiplicative Comparison Word Problems
URL: https://www.engageny.org/resource/grade-4-mathematics-module-3-topic-overview
Description:

Students begin Topic A by investigating the formulas for area and perimeter. In Lesson 1, they use those formulas to solve for area and perimeter and to find the measurements of unknown lengths and widths. In Lessons 2 and 3, students use their understanding of the area and perimeter formulas to solve multiplicative comparison problems including the language of times as much as with a focus on problems using area and perimeter as a context (e.g., A field is 9 feet wide. It is 4 times as long as it is wide. What is the perimeter of the
field?) (4.OA.2, 4.MD.3). Students create diagrams to represent these problems as well as write equations with symbols for the unknown quantities.

Description:

In this interactive activity, students will be led through steps to measure and calculate the perimeter of polygons. There are teaching activities as well as practice activities available. A handout that reviews the steps taught during the interactive is available to be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.
