Ever notice how kids have a hard time keeping track of which meaning goes with the word "area" and which meaning goes with the word "perimeter"?
My kids used to, but then I made up a couple of tricks that helped the kids remember which one was which.
Area is measuring squares. Both words have the are in them, which I emphasize when I teach it. I also make a hand motion that reminds the children that we're talking about a full surface.
Perimeter measure around the sides. I emphasize that r in both words, and make a hand motion moving around.
You know, I'm kind of obnoxious about the way I repeat it over and over, making the same hand movements, and emphasize the are for area and the r in perimeter.
But I've had former students tell me they remembered the difference between area and perimeter and they repeated the movements I used to make when they were in my class.
I also made up this activity for the children to practice the differences between the two.
When my students do this activity, they repeat my gestures every time!
