Question 1

1.

You Try--Rectangles A and B are scale drawings. The perimeter of Rectangle A is 6 centimeters.

What is the perimeter of Rectangle B?

"The perimeter of Rectangle B is..."

CFS:
#1: Accurately identifies the scale factor
#2: Accurately writes and solves equation to find new length

Question 2

2.

Right Way--The larger arrow is a scale drawing of the smaller one. If the distance around the smaller arrow is 25.66 units, what is the distance around the larger arrow?

a) Find the scale factor as a percent.

b) Write an equation to find the distance around the larger arrow.

"The distance around the larger arrow is..."

CFS:
#1: Accurately identifies the scale factor
#2: Accurately writes and solves equation to find new length

Question 3

3.

Missing--The smaller triangle is a scale drawing of the larger triangle.
What is the value of the missing side of the smaller triangle?

"The missing side of the smaller triangle is..."

CFS:
#1: Accurately identifies the scale factor
#2: Accurately writes and solves equation to find new length

Question 4

4.

Grid--The smaller drawing on the right side is a scale drawing of the larger one. The perimeter of the larger drawing is 39.4 units. Find the distance around the smaller drawing.

Hint: You can find the scale factor by first finding the vertical length of each shape.

Question 5

5.

SPICY--Try if you have time.

SpaceX--The figure is a diagram of a model rocket and is a 2-D scale drawing. The length of the model rocket is 2.5 feet and the wing span is 1.25 feet.

If the length of the actual rocket in real life is 184 feet, write an equation to find the wing span of the actual rocket.

BONUS: Write the scale factor as a percent (it will be a very, very large number)

CFS:
#1: Accurately identifies the scale factor
#2: Accurately writes and solves equation to find new length

Nice work! Please continue working on other skills on IXL. 

Wait for instructions to move onto the exit ticket.

Question 6

6.

Hot Wheels--Race Car #2 is a scale drawing of Race Car #1.

a) What is the scale factor as a percent?

b) Use an equation to find the height of Race Car #2.

"The height of Race Car #2 is..."
