Objective and Summary:
SWBAT determine whether a scale drawing is an enlargement or a reduction by computing the scale factor

Designs--An architect is drafting a design for her new building. She drew a set of original blueprints, then used computer software to change the size of her design.

a) What is the scale factor? (Enter a number)

CFS:
#1: Accurately computes the scale factor

b) Explain why this is an enlargement or reduction.

"This is an (enlargement / reduction) because..."

CFS:
#2: Uses mathematical evidence to explain an enlargement or reduction

Downsize--A large portrait is being resized to fit on regular copy paper.

a) What is the scale factor?

CFS:
#1: Accurately computes the scale factor

b) Explain why this is an enlargement or reduction.

"This is an (enlargement / reduction) because..."

CFS:
#2: Uses mathematical evidence to explain an enlargement or reduction

MEDIUM Problems

Art Project--Ms. Zermeno needs to cut out paper shapes for students to glue onto collages today. She wants to change the shapes so that they are easier to work with.

a) What is the scale factor?

CFS:
#1: Accurately computes the scale factor

b) Is this an enlargement or a reduction?

Notes--Ms. Ixcot-Nario often has kids draw scale shapes in 8th grade. Hugo took his original rectangle and made it smaller.

a) What was the scale factor that he used?

b) Can you find the missing side of the scale drawing? Explain or show calculations for how you know

"The missing side is _________ because..."

SPICY Problems (Only try if you have time)

Flag--Marcos wants to paint a Colombian flag for his school’s Flag Day. He prints out a small version of the flag and wants to enlarge it.

a) Each of the measurements are labeled with a letter. What would their new measurements be if Marcos draws the scale drawing 3 times larger? You can fill in the table directly on formative.

b) Draw and label your new scale drawing.

Class Prep--Mr. Espinoza is trying to get his classwork ready for next week's lesson. He's not sure if the rectangle he has is being enlarged or reduced.

a) What is the scale factor?

CFS:
#1: Accurately computes the scale factor

b) Explain why this is an enlargement or reduction.

"This is an (enlargement / reduction) because..."

CFS:
#2: Uses mathematical evidence to explain an enlargement or reduction

Nice work! Push yourself ahead by...

1) Practicing your lowest diagnostic skills

2) Working ahead on more advanced topics (equations, algebra, etc.)
