Free Printable Perimeter of a Rectangle Worksheets for Year 2

In 2nd grade, students move from counting units to using addition. They should be taught to find the perimeter by adding the lengths of all four sides (e.g., 5 + 3 + 5 + 3). This repeated addition reinforces their fluency with addition and connects it to a real-world geometric application.

Start with rectangles where all four side lengths are labeled. Progress to problems where only the length and width are given, requiring students to know that opposite sides are equal. Simple word problems with whole numbers, such as finding the perimeter of a rectangular playground, are also effective.

The most common mistake is for students to add only the two given numbers (the length and the width) and forget to include the other two sides. Reinforce that a rectangle has four sides that must all be included in the total.

This worksheet is available as a printable PDF and in a digital format, accommodating various teaching environments. You can print it for a whole-class activity or independent seatwork. After students complete the paper version, you can use the Wayground for Teachers app to scan and grade their submissions using the provided answer key.

As per Common Core, 2nd grade math focuses on solving problems involving length. Calculating perimeter directly applies students' ability to use addition to solve word problems involving lengths that are given in the same units. This skill is a direct bridge to understanding the properties of shapes in third grade.

Use a visual and kinesthetic approach. Have the student trace all four sides of a physical or drawn rectangle with their finger, saying the length of each side as they go. Then, have them write down the addition sentence with all four numbers before they calculate the sum.
