Measurement is more than just grabbing a ruler and measuring the length of an object. There’s width, weight, circumference, area, perimeter, and more, so much more.
I love measurement activities because they’re so often hands-on activities, and this idea is no exception. This perimeter activity is a fun invitation you can quickly set-up so your child can practice measuring and calculating. So, grab a few items and let’s create a Perimeter Lab.

Set-up is easy.
It’s very easy to set up this hands-on perimeter activity.
First, you’ll need some measurement tools: a ruler, pencil, and your perimeter lab recording sheet.
You’ll also need a variety of things to measure. Choose items of various sizes that are rectangular or square. Look for books, boxes, board or card games. You could also cut pieces of paper into different sized squares or rectangles.
How to find the perimeter of an object.
Does your child already know how to find the perimeter or are they just learning?
If they already know, set them loose with this math invitation for a fun way to review perimeter.
But, if they need a little help, use the recording sheet to walk them through the process. First, record the name of the object you’re measuring. Then grab the ruler. You’ll want to measure side A, side B, side C, and side D. (See the picture above for reference.) Record all the measurements on the sheet. Add all the sides together to find the perimeter of the object.
Since we’re just grabbing random objects to measure, you may want to alter this project just a bit to fit with your child’s ability.
Depending on your child’s ability, you may want to have them round their measurements to the nearest inch or half-inch. If they’re comfortable with fractions or decimals, they can use more specific measurements.
If all you want to do is get comfortable with calculating perimeter, then getting exact measurements aren’t necessary.
Check your work.
There’s no answer key to this project. You can pre-measure all the items (if you really want to), look over the process and the answers to see if your child is correctly figuring perimeter, or have your child double-check their work.
Correct answers are important in math, but so is learning the process. Know the process first and then focus on finding the correct measurement.
A Perimeter Lab is a fun way to learn the process behind calculating perimeter. You’re doing real-life measurements and not just looking at a drawing on a piece of paper. It’s fun, it’s hands-on, and it’s a great way to extend learning at home.
