Objective and Summary:
SWBAT compute actual lengths when given a scale drawing

Gardening—Mr. V loves vegetables and has a kale garden in his backyard. Every 1/2 centimeter in the scale drawing corresponds to 3 meters in real life.
CFS:
#1: Accurately computes scale factor
#2: Accurately computes real measurements using the scale factor

Use the provided information to find the scale factor or scale ratio.

What are the actual dimensions (in meters) of the kale garden?

YouTube--Ms. Paul is doing an apartment tour on her YouTube channel. A blueprint shows that 4 inches in the drawing corresponds to 12 feet in the actual apartment.

CFS:
#1: Accurately computes scale factor
#2: Accurately computes real measurements using the scale factor

Use the provided information to find the scale factor or scale ratio.

What are the dimensions of Ms. Paul's apartment in real life?

"The actual dimensions of Ms. Paul's apartment are _ feet by feet"

MEDIUM Problems

Tablet--Jeeve Stobbs created an ad for his new tablet. The picture in the ad is a scale drawing of the actual iSquare. The legend he used states that every \frac{1}{4} inch in the ad represents 1 inch in real life.

What are the actual dimensions of the iSquare?

"The actual dimensions of the iSquare are by _"

CFS:
#1: Accurately computes scale factor
#2: Accurately computes real measurements using the scale factor

Backyard--A scale drawing of a rectangular backyard is drawn using a scale of \frac{3}{4} inch corresponding to 5 feet in real life.

What are the dimensions (in feet) of the backyard?

"The dimensions of the backyard are _ by ____"

CFS:
#1: Accurately computes scale factor
#2: Accurately computes real measurements using the scale factor

Tourism—The city of St. Louis wants to put the following image as a welcome sign on a
billboard for tourists. The picture will be enlarged so that each 1/2 inch on the drawing will represent 7 feet in real life.

a. Will the real-life image fit on a billboard that is 30 feet tall? Explain using mathematical evidence.

SPICY Problems

Airplane—In a scale drawing of an airplane, 1 inch equals 3 meters. The scale drawing of the
airplane shows a length of 10 2/3 inches.

a. Draw a sketch of the scale drawing and label with its length.

b. Use the scale to find the length of the airplane in real life.

Gundam—Mr. H used to build figurines from a popular TV show when he was growing up. Each 1/4 inch in the figurine is supposed to represent 5 meters in real life.

a. What is the actual height of the robot?

Gardening--Mr. Mancini loves vegetables and has a kale garden in his backyard. Every \frac{1}{2} centimeter in the scale drawing corresponds to 3 feet in real life.

What are the actual dimensions (in feet) of his kale garden?

"The actual dimensions of Mr. Mancini's garden are _ by __"

CFS:
#1: Accurately computes scale factor
#2: Accurately computes real measurements using the scale factor
