Perimeter Worksheets: Perimeter of Regular & Irregular Polygons Game

Perimeter of Regular and Irregular Polygons: Math Game

• Here’s a fun math game that incorporates critical thinking and math strategy.

• It could be a great addition to your geometry or measurement unit in grades 4-6.

• Students will practice drawing regular and irregular polygons with given perimeters. They will need to use math skills including addition, division, or knowledge of factors to determine how to make a specific kind of shape with a provided perimeter.

• This game is ready-to-go! Simply show the two sample rounds to your students to teach them how to play.

• Then each student needs a six-sided die and the three-page game.

• Students can play on their own or in small groups where they can share ideas. There are three rounds to play!

• A question to help students notice the strategy of the game is included. Students should notice that it is easier to make a regular shape if the perimeter is divisible by the number of sides of the shape. For example, to make a regular pentagon with the digits 5 and 1, I would make the perimeter 15 units, so each side could be 3 units long.

• A bonus question for early finishers is also included. ANSWER: A decagon has 10 sides. So, a regular decagon could easily have a perimeter of 10, 20, 30, 40 units. That could be hard in this game because the die does not have a zero.

Grades to Use With:

This game is designed for students in grades 4-6 who are learning about perimeter of polygons, regular vs irregular polygons, factors, and division. It's also a great way to practice critical thinking and strategy.
