Perimeter
Draw a square.
One side is 6cm.
What is the perimeter?
Give an equation and label.
6 + 6 + 6 + 6 = 24cm
Draw a square.
One side is 3ft.
What is the area?
Give an equation and label.
A = L x W
3 x 3 = 9 square ft
0 x 4 = 0
What property is shown?
Zero Property
Draw a rectangle.
The length is 7in. The width is 3in.
What is the perimeter? Give an equation and label.
7 + 3 + 7 + 3 = 20in
Draw a rectangle.
The length is 4cm. The width is 3cm.
What is the area? Give an equation and label.
A = L x W
4 x 3 = 12 square cm
7 x 1 = 7
What property is shown?
Identity Property
Draw a rectangle.
The length is 9ft. The width is 3 ft.
What is the perimeter AND area? Give equations for both and labels!
Perimeter: 9 + 3 + 9 + 3 = 24ft
Area: 9 x 3 = 27 square ft
Draw a rectangle.
The area is 18 square ft.
The length is 9 ft.
What is the missing side?
Give an equation and label.
A = L x W
18 = 9 x ?
18 divided by 9 = 2
? = 2 ft
5 x 4 = 20, 4 x 5 = 20
What property is shown?
Commutative Property
Draw a rectangle.
The area is 30 square in. The length is 6in. What is the other side?
What is the perimeter?
Give equations and labels for both!
A = L x W
30 = 6 x ?
30 divided by 6 = 5, so the missing side is 5in.
Perimeter:
6 + 5 + 6 + 5 = 22in
Draw a rectangle.
The area is 28in.
The width is 4in.
What is the length?
Give an equation and label.
A = L x W
28 = ? x 4
28 divided by 4 is 7
? = 7in
3 x 2 x 5
6 x 5 = 30, or 3 x 10 = 30

Associative Property
Draw a rectangle.
The area is 42 square m. One side is 7m.
What is the perimeter? Give equations for all steps and label!
Find the missing side first- 42 divided by 7 = 6m
So the perimeter is 7 + 6 + 7 + 6= 26m
Draw a rectangle.
The perimeter of the rectangle is 24m.
One side is 8m.
What is the area? Solve giving all the steps needed!
First solve for the missing side:
Opposite sides are the same, so two sides are 8m;
8 + 8 = 16m
24 - 16 = 8, divide 8 in half and you get 4
so the missing side is 4m, now you have length and width
8 x 4 = 32 square m
7 x 9 = ?
5 x 9 = 45
2 x 9 = 18
45 + 18 = 63
