About this resource
Description
Perimeter is the total distance around the outside of a two-dimensional shape, and learning to add up the lengths of every side is an essential third grade measurement skill. This Perimeter Shape Problems Worksheet gives students focused practice finding the perimeter of squares, rectangles, triangles, pentagons, hexagons, and trapezoids when the length of each side is labeled. By counting and adding the sides, children build a concrete understanding of what perimeter really measures.
This perimeter of shapes worksheet presents eight clearly drawn figures, each with its side lengths marked, and a solid line where students write the total perimeter with its correct unit. To use it, have students work down the page one shape at a time, adding the side lengths and labeling each answer in centimeters, inches, meters, or feet. The included answer key makes checking quick for teachers, parents, and homeschoolers.
What’s Included
- 1 print-ready PDF worksheet
- 8 labeled shape problems covering a variety of polygons
- Complete answer key
This resource helps kids learn perimeter in three important ways. First, it connects the abstract idea of perimeter to real, visible shapes, so students see exactly which lengths they are adding. Second, the mix of triangles, quadrilaterals, pentagons, and hexagons strengthens addition fluency while reinforcing that perimeter is found the same way for every polygon. Third, the variety of units encourages students to read carefully and attach the correct label to each answer, a habit that supports accurate measurement work all year long.
Teachers and parents can extend this perimeter shape problems worksheet in many fun ways. Hand students a ruler and ask them to measure and find the perimeter of classroom objects like books, desks, or tablets. Use painter’s tape to outline shapes on the floor and have children walk and count the perimeter step by step. Challenge students to draw their own polygon, label the sides, and trade papers to solve, or connect the skill to area by comparing two different shapes that share the same perimeter.
