Objective and Summary:
SWBAT compute actual areas from a scale drawing

Question 1

1.

G3--A scale drawing of the 7th grade math room is below. 1 inch on the drawing corresponds to 3 feet in the actual classroom.

What is the actual area of Mr. Espinoza's classroom?

"The actual area of Mr. Espinoza's classroom..."

CFS:
#1: Accurately computes actual measurements using the scale factor
#2: Accurately computes actual area using the correct area formula

Question 2

2.

Mural--Mr. Hernandez wants to paint a giant portrait of our mascot Prizer on the cafeteria wall. He sketches an image that is 10 inches by 8 inches. He wants every 1 inch in the sketch to represent 5 feet in the actual painting.

What is the area Coach needs to paint over on the cafeteria?

"Coach needs to paint over..."

CFS:
#1: Accurately computes actual measurements using the scale factor
#2: Accurately computes actual area using the correct area formula

MEDIUM Problems

Question 3

3.

Math Problem--Ms. Ixcot-Nario asks a student to take her drawing of a triangle and enlarge it. If she wants every inch on her drawing to be 2.5 feet on the larger poster, what will the area of the poster be?

"Ms. Ixcot-Nario's poster will be..."

CFS:
#1: Accurately computes actual measurements using the scale factor
#2: Accurately computes actual area using the correct area formula

Question 4

4.

Floor Plan--1 inch in the blueprint corresponds to an actual length of 12 feet.

What is the area of the kitchen?

"The area of the kitchen is..."

CFS:
#1: Accurately computes actual measurements using the scale factor
#2: Accurately computes actual area using the correct area formula

Question 5

5.

SPICY--Try if you have time

Floor Plan 2--1 inch in the blueprint corresponds to an actual length of 12 feet.

What is the area of the dining room? (The L-shaped area)

"The area of the dining room is..."

CFS:
#1: Accurately computes actual measurements using the scale factor
#2: Accurately computes actual area using the correct area formula

Question 6

6.

SPICY--Try if you have time

Park Place--A scale drawing of a local park is drawn using a scale of \frac{2}{3} inch corresponding to 10 feet in real life.

What is the actual area of the park?

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

Question 7

7.

Blueprints--Jasmine decides to make a scale drawing of her room to practice for math class. 1 inch in the scale drawing below represents 4 feet in the actual room.

How many square feet is Jasmine's actual room?

CFS:
#1: Accurately computes actual measurements using the scale factor
#2: Accurately computes actual area using the correct area formula
