Perimeter of a Rectangle Poster

Support Student Learning with our Perimeter Anchor Chart 

Use this poster to supplement your mathematics and perimeter lessons.

As students begin to understand the concept of perimeter, different formulas will be introduced. It can be difficult for students to remember which formula is used for a specific shape. This poster provides a visual display to remember the formulas for finding the perimeter of a rectangle. 

How to Make the Most of Your Perimeter Anchor Chart

1. Print the poster on paper or cardstock and display it in your classroom for students to reference when doing independent work.
2. Print the poster on letter-size paper, slip it into a clear sleeve, and use it in your guided groups as a reminder.
3. Print the poster on letter-size paper, slide it into a clear sleeve, and hang it on a ring as a reference tool for a learning center.
