Area and Perimeter
One of the fourth grade standards in math is that students be able to find the area and perimeter of rectangles/squares and simple polygons. For the third year in a row students have a difficult time grasping this concept and being able to differentiate between the two. Does anyone have a really good saying or some type of device to help students remember the difference between area and perimeter? Thanks in advance!

I used to talk about the rim of a glass because the word "rim" is hiding inside of "perimeter." Otherwise, we would chant it over and over and over again. There was no rhyme or anything fancy.

ReplyDelete"Here we go round the perimeter fence, the perimeter fence, the perimeter fence, Here we go round the perimeter fence, add up all the sides"
or
Area = all
Perimeter = rim
or
A=SS (SidexSide)
P=SSSS (Side+Side+Side+Side)
Without commenting on it or acknowledging chuckles... maybe the class will remember that on their own.. :)
Love it guys! I am not much of a musical person, but I think I can try to sing the mulberry bush song. I really like the "rim" as well. Thanks for the help.
