Finding the Perimeter Worksheet – 3rd Grade Geometry & Measurement

The Finding the Perimeter Worksheet gives third grade students focused, no-prep practice with perimeter. It is a print-and-go math page that fits easily into a mini-lesson, a center rotation, or a quick review day.

Learning objective: Students will practice perimeter and apply the skill independently by completing each task on the page.

Why it works: Practice like this gives students a chance to try perimeter on their own after you teach it. Because the page is quick to complete and easy to review, it fits into almost any part of the school day.

What's included:

• 1 printable worksheet page

• Clear, student-friendly directions

• 2 practice sections (Part A to Part B)

• Answer key (1 page)

• Cover page

How it's organized: The page opens with these directions: "Explain how you solved this problem." The practice is split into 2 parts, so students can work through it in clear steps.

Grade level: Designed for third grade students. It also works well for second grade and fourth grade students who need extra practice or a fresh review.

How to use it: It works well for whole-class lessons, small groups, early finishers, homework, review days, intervention time, and sub tubs.

Answer key: An answer key is included, so you can check work quickly or let students self-correct.

Teaching tips and variations:
