How do you find the perimeter of a figure?

Day 1: Exploring Perimeter with a Geoboard

PRE-ASSESSMENT TOOL

Today we will be exploring perimeter using a type of measurement called units. We will measure the perimeter of several different figures on a geoboard.

Use the following websites to practice finding perimeter.

***Remember: The distance from one point to another point on the geoboard is one unit.

1) Make a figure with the perimeter of 8 units.

2) Make a figure with the perimeter of 14 units.

3) Figure out how many figures you can make with the perimter of 12.

Day 2: Roll a Polygon Game (Finding Perimeter)

You will be given two colored number cubes. The red cube will represent the width of the figure and the blue cube will represent the length of the figure. After each roll, record the length and width numbers on your record sheet. Construct the figure using snap cubes. Then, find the perimeter and draw a diagram of the figure.

***This game requires you to measure in units.

Activity: Odd Shapes? What is the perimeter? Use square tile shapes to find the perimeter in this activity.

Activity: Further Investigations of Perimeter (Around the Classroom)

Day 3: Exploring Ways to Measure and Find Perimeter of a Figure

Today we will be looking at the many different ways you can measure and find perimeter.

Questions to consider:

1) Can different shaped figures have the same perimeter?

2) Are there different forms of measurement you could use to find perimeter?

We will be using inches today as a form of measurement to find perimeter.

Activity: Fantasy Playground Perimeter Challenge

***There is more than one way to find perimeter!

Day 4 and 5: Create a Fantasy Playground

Students will be given a blank centimeter grid paper to create a fantasy playground. They will have to select three equipment items from the fantasy equipment list and properly place them on the paper. They must include the measurements of two sides of the equipment, one for the length and one for the width. Upon completion of the fantasy playground students will respond to the Journal prompt related to the new fantasy playground creation.
