Area and Perimeter

I just started teaching area and perimeter and the students understand how to find the answer if they are told to find either the area or perimeter. However, they don't understand how to figure out which to choose when they are given word problems. Does anyone have any suggestions for me?

In ancient times - when I went to school - we were told to think, "Am I going to walk it (perimeter/distance) or paint it (area/cover).?"

I used that the few times I had to teach math and the kids seemed to get the idea.

MY Clue

The clue I use in my classroom is--think about the cop shows and how they say someone needs to "search the perimeter"...this means the cops walk ALL the WAY AROUND the property looking for the criminal....so perimeter is the distance around...

I tell the kids to think of area as an "area rug" which we would buy to cover a carpet or floor in a room, the area rug covers the entire area...

To go along with all of this I also throw in volume, I write the word volume on the board and then draw a little stem and base on the V in volume to make it looks like a fancy glass (wine glass to us adults), I tell the kids, "here is your glass, you FILL up your Glass, therefore volume is how much something will hold"

I have also used the idea of a swimming pool to cover all three concepts, perimeter would be to "walk around the pool", area would be the entire bottom of the pool, and volume would be the amount of water to fill the pool

On teacher tube, there is a video by Mrs. Burke about perimeter and area. It is actually a rap that teaches the difference between the two things. You can print off the lyrics and have the students follow along with the hand motions. My students love this!
