JANUARY 16, 2008: LESSON #8: AREA AND PERIMETER
Two of the most confused terms in elementary school math for students are the terms area and perimeter.
We have 2 easy chants to share with kids to help them remember these terms.
Perimeter means...
All the way around...you add up the lengths!
A-R-E-A
You count the squares inside, hey!
There are so many activities that parents can be doing at home to help reinforce these words/terms.
Here are some activities:
- Quickly cut out 1 inch squares out of paper. This is done at a fast pace if you first cut the paper into strips, and then cut the squares. Have children pretend the squares are tiles. Ask them to make a 2 X 3 rectangle. Then, try various shapes. Ask, can you make a 5 inch X 3 inch rectangle?
- Use the squares to make a rectangle (for example, a 3 inch X 4 inch rectangle). Ask your child for the dimensions and see if they can say that it is a 3 X 4.
- Make a book with your child. On each page, draw 1 shape. Have them outline the shape in one color (perimeter) and have them shade in the shape in the other color (area). Have them "read" the book to you. For example, if the first page is a picture of a square, pretend the child outlined it in blue and shaded it in red. They would say, "The square has a blue perimeter and a red area."
- Sometimes simply using the language of math in our everyday lives is important! For example, use the term "perimeter" when children are cleaning. For example, "Did you pick up your toys around the perimeter of
the room?" Or, "I am going to go pull the weeds around the perimeter of the yard."
