Perimeter and Area Fun!


Perimeter is the distance around a two-dimensional shape.

Example 1: the perimeter of this rectangle is 7+3+7+3 = 20

perimeter of rectangle

Example 2: the perimeter of this regular pentagon is 3+3+3+3+3 = 5×3 = 15

We are working on multiplication in class!

An array is a rectangular pattern of items arranged in columns and rows.

When we describe arrays, we write the number of columns first.

Therefore, this array would read 6 x 3!

Try the array activities posted here for additional practice.

A Game to Print and Try at Home: Racing Rectangles….click link below to print out the grid for playing.

Racing Rectangles is a game that can help reinforce arrays and multiplication.  Students, working in pairs, take turns rolling two dice.  Each student must choose a different colored marker or crayon to use.  The student outlines and fills in a rectangle that matches what they rolled.
For example, if the student rolled a 4 and 3, that student would fill in a 4×3 rectangle on the grid.  The player then writes the total number of squares inside the rectangle.
A player loses a turn when his or her rectangle cannot fit on the game board.  Play continues back and forth until neither player can’t draw a rectangle.
Students count up their total of squares they colored.
The winner is the one with the highest number of squares filled in.
Here is an example of what a game board might look like…

Here’s an online lesson explaining how multiplication and division are related.


We are currently working on identifying number patterns using a hundreds chart. These two activities online may help students review at home.
