Our elementary school measured the perimeter around the school and then discussed how many times they would have to go around the school to make it to Disney Land or NYC or Canada etc.... My daughter would come home and tell me when her class had made it to many different locations! They were incorporated landmarks and wellness with perimeter.

u can make them cover something with a thing like fabric but dont let use a ruler...
Maybe they can only look it on hand then they try to cover...

Ask them where they have seen fences in their neighborhood, and how the builders knew how much fencing to order. Most school playgrounds are fenced, so make a quick sketch of the playground, or separate Kindergarten playground, and ask the question again. Most students will begin to discuss the need to know how far "around" the playground the fence will extend.

This is a cool idea for teaching perimeter, though it is meant for 6th graders I think you could modify for 3rd graders.

well let's not ignore the obvious - measuring your waistline, neckline, arm width so you can get suited up. We don't want some apparel that doesn't fit well now do we?

If you have a decorative border around one of your display boards, ask kids how they would figure out how much border you needed to buy. Make it a project. Tell them borders come in packages of x feet. How many packages would you need to put a border around a bulletin board. If you classroom has windows, ask them how a carpenter would know how much wood is needed to frame the window. Let it get messy, What do you do with overlaps? What do you measure to find the distance around a shape?
