PSA9CT2 - Student-Facing Tasks---7.1 Lesson 7: Scale Drawings: Student Facing Tasks (7.G.A.1)

Here are some drawings of a school bus, a quarter, and the subway lines around Boston, Massachusetts. The first three drawings are scale drawings of these objects.

The next three drawings are not scale drawings of these objects.

Discuss with your partner what a scale drawing is.

Part A)

Your teacher will give you a scale drawing of a basketball court. The drawing does not have any measurements labeled, but it says that 1 centimeter represents 2 meters.

Measure the distances on the scale drawing that are labeled a–d to the nearest tenth of a centimeter. Record your results in the table.

Create and fill in the table using the table button

Part B)

The statement “1 cm represents 2 m” is the scale of the drawing. It can also be expressed as “1 cm to 2 m,” or “1 cm for every 2 m.” What do you think the scale tells us?

Part C)

How long would each measurement from the first question be on an actual basketball court? Explain or show your reasoning.

Part D)

On an actual basketball court, the bench area is typically 9 meters long.

Without measuring, determine how long the bench area should be on the scale drawing.

Type your answer below as a number (example: 5, 3.1, 4 1/2, or 3/2):
Part E)

Part A)

Here is a scale drawing of some of the world’s tallest structures.

About how tall is the actual Willis Tower? About how tall is the actual Great Pyramid? Be prepared to explain your reasoning.

Part B)

About how much taller is the Burj Khalifa than the Eiffel Tower?

Part C)

Part D)

Measure the line segment that shows the scale to the nearest tenth of a centimeter. Express the scale of the drawing using numbers and words.

Part A)

A scale drawing of a school bus has a scale of  inch to 5 feet. If the length of the school bus is 1/inches on the scale drawing, what is the actual length of the bus?

Type your answer below as a number (example: 5, 3.1, 4 1/2, or 3/2):
Part B)

Part C)

A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width of the lake is 1,000 m, what is the width of the lake on the scale drawing?
