Use this interactive video lesson to introduce or reinforce finding perimeter of a polygon, including when sides are missing and perimeter is given.

Video lessons are great for math stations, sub work, homework, and review!

Video on TPT is streaming. That means the video is embedded for playback ON Teachers Pay Teachers. As long as you have an account and are able to access TPT, you’ll be able to watch your video anywhere.

I have also included the link to the video on the Student Video Sheet so that you can watch it on multiple devices OUTSIDE of Teachers Pay Teachers.

In this lesson you will determine the perimeter of a polygon. You will determine a missing length when given the perimeter and remaining side lengths.

The video lesson is about 11 minutes long. Students work alongside me on their Video Recording Sheet as they watch the video.

After watching the video, they will show what they have learned from the lesson as they complete the independent questions on the back of their video sheet.


The video is embedded for playback ON Teachers Pay Teachers. The video link is also listed on the student Video Recording Sheet.
