Module 7 Lesson 12Measure side lengths in whole number units
to determine the perimeter of polygons.
Perimeter: The distance around a two-dimensional shape.

Multiply by 7
7 x 7 = _____
Let’s skip-count up by Sevens to find the answer. Hold up a finger for each seven.
7 14 28 35
49
49 9 x 7 = _____63
Let’s see how we can skip-count start at 35. Start by holding up five fingers. Raise one more finger each time we count.
6 x 7 = _____42
21
56 63 7042
Let’s see how we can skip-count down from 70. Start by holding up 10 fingers. Put down one finger each time we count down.

First let’s skip count by three 10 times.
Now let’s count up to 10 groups of 3, or 10 threes.
And last, let’s say the multiplication sentences!

Concept Development
We have learned that the “boundary” of a shape is the shape’s perimeter. Discuss with your partner: What forms the boundary of this shape?
That’s right! The sides of the shape form the boundary.

Concept Development
What can we use to measure the perimeter of this shape? A ruler!

Concept Development
Let’s try it again!I will pass out the lesson template. Get out your ruler. Measure the sides and calculate the perimeter of each shape.We have already measured shape A.
Measure to the nearest centimeter.

Try it Out!
At lunch, Angela measure the sides of a square napkin. Each side measures 6 inches. What is the perimeter of the napkin?
6 inches
6 x 4 = 24.The perimeter of the napkin is 24 inches.
