# Unit 1: My Reflections

## Lesson 1: What are Scaled Copies?

- I can describe some characteristics of a scaled copy.
- I can tell whether or not a figure is a scaled copy of another figure.

## Lesson 2: Corresponding Parts and Scale Factors

- In a pair of figures, I can identify corresponding points, corresponding segments, and corresponding angles.
- I can describe what the scale factor has to do with a figure and its scaled copy.

## Lesson 3: Making Scaled Copies

- I know what operation to use on the side lengths of a figure to produce a scaled copy.
- I can draw a scaled copy of a figure using a given scale factor.

## Lesson 4: Scaled Relationships

- I can use corresponding distances and corresponding angles to tell whether one figure is a scaled copy of another.
- When I see a figure and its scaled copy, I can explain what is true about corresponding angles.
- When I see a figure and its scaled copy, I can explain what is true about corresponding distances.

## Lesson 5: The Size of the Scale Factor

- I can describe the effect on a scaled copy when I use a scale factor that is greater than 1, less than 1, or equal to 1.
- I can explain how the scale factor that takes Figure A to its copy Figure B is related to the scale factor that takes Figure B to Figure A.

## Lesson 6: Scaling and Area

- I can describe how the area of a scaled copy is related to the area of the original figure and the scale factor that was used.

## Lesson 7: Scale Drawings

- I can explain what a scale drawing is, and I can explain what its scale means.
- I can use a scale drawing and its scale to find actual distances.
- I can use actual distances and a scale to find scaled distances.

## Lesson 8: Scale Drawings and Maps

- I can use a map and its scale to solve problems about traveling.

## Lesson 9: Creating Scale Drawings

- When I know the actual measurements, I can create a scale drawing at a given scale.
- I know how different scales affect the lengths in the scale drawing.
- I can determine the scale of a scale drawing when I know lengths on the drawing and corresponding actual lengths.

## Lesson 10: Changing Scales in Scale Drawings

- Given a scale drawing, I can create another scale drawing that shows the same thing at a different scale.
- I can use a scale drawing to find actual areas.

## Lesson 11: Scales without Units

- I can use scales without units to find scaled distances or actual distances.
- I can explain the meaning of scales expressed without units.

## Lesson 12: Units in Scale Drawings

- I can write scales with units as scales without units.
- I can tell whether two scales are equivalent.

## Lesson 13: Draw It to Scale

- When given requirements on drawing size, I can choose an appropriate scale to represent an actual object.
- I can create a scale drawing of my classroom.
