Lesson 1 Solving Problems Involving Scale

What is 'scale'?

• the relationship between a length in a model or map to the actual length

• a drawing that shows a real object changed to a larger or smaller size

• the space inside a shape

• the length of one direction in a figure

what is a drawing that shows a real object changed to a smaller or larger size?

• scale

• scale drawing

• area

• unit rate

What is the 'scale factor'?

• existing in real life; not a model

• how much something weighs

• the amount by which you multiply all the side lengths to make a scale drawing

• the length of one direcction of a figure

Define 'area'.

• a drawing that shows a real object chaned to a smaller or larger size

• the length of one direction in a figure

• show how your answer is correct using proof and examples.

• the space inside a shape; measured in square units

What is a dimension?

• the length of on direction of a figure

• the space inside a shape

• the part of a rate comparison that is represented by a number

• the amount by which you multiply all the side lengths to make a scale drawing

Unit rate is...

• the space inside a shape

• the part of a rate comparison that is represented by a number

• the relationship between a length in a model or map to the actual length

• the length of one direction in a figure

what does 'actual' mean?
