Area or Perimeter?

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!

  3. I also tell my kids that the word perimeter has the word RIM in it. Then I draw the basketball hoop and show them the RIM and a tire and show them the RIM and they notice that they both go around. Then we make the connection of RIM in peRIMeter. . . it goes around.
    You can also sing. . .
    Perimeter goes around,
    Perimeter goes around,
    OH OH don't cha know,
    Perimeter goes around. . . .

    sing to the toon of the farmer in the dell

      This is great! I've got a couple of huge basketball fans in my class. I showed them this today, and it clicked!
