It’s got the word “rim” in it- so that’s what we measure and add!!

We’re learning the basics of perimeter this week.┬áThis is a vocabulary word we’ve used in class all year (example: “sit around the perimeter of the rug…”), but now we’re connecting it to our math lessons. We’re practicing different procedures for figuring out the perimeter of polygons. Sometimes we “walk” around the whole figure, counting as we go, but most of the time we measure each side and then just add them up- like the video here says. Finally, we’re connecting it to real life by thinking about why we would ever need this. We certainly want to get the correct size fence so Zippy doesn’t get out, right?!
