7th Math Unit 1 Day 18 - 9/28

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 ______________"

#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.

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 ____________"

#1: Accurately computes scale factor

#2: Accurately computes real measurements using the scale factor

Surfboard--An advertisement for a surfboard on Amazon shows its length as 4\frac{1}{2} inches. Find the actual length of the surfboard if 2 inches on the website corresponds to 4 feet in real life.

"The actual length of the surfboard is..."
