Finding the Perimeter of Shapes Grid Worksheet – 3rd Grade Measurement

Build strong perimeter skills with the Finding the Perimeter of Shapes Grid Worksheet. This third grade math printable keeps the focus on one skill so students can practice it with confidence.

Learning objective: Students will build accuracy and confidence with perimeter through short, focused practice that reinforces what was taught in class.

Why it works: Each page targets one skill, so students get meaningful repetition without feeling overwhelmed. The layout is clean and uncluttered, which helps young learners focus on the task instead of the decorations.

How it's organized: The page opens with these directions: "Find the perimeter of each shape. Each square on the grid is 1 centimeter (cm)." Students then complete the practice items in order and check their work before turning it in.

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: Use it for whole-group practice, small-group instruction, independent work, centers, morning work, homework, or an emergency sub plan.
