__Common Core Standards for this Unit:__- 7.RP.A.2 Recognize and represent proportional relationships between quantities.
- 7.RP.A.2a Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
- 7.RP.A.2b Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
- 7.RP.A.3 Use proportional relationships to solve multistep ratio and percent problems.

__Goals for this Unit:__- Similar Figures Understand what it means for figures to be similar

- Identify similar figures by comparing corresponding sides and angles

- Use scale factors and ratios to describe relationships among the side lengths, perimeters, and areas of similar figures

- Use algebraic rules to produce similar figures

- Recognize when a rule shrinks or enlarges a figure

- Reasoning With Similar Figures Develop strategies for using similar figures to solve problems

- Predict the ways that stretching or shrinking a figure will affect side lengths, angle measures, perimeters, and areas

- Use scale factors or ratios to find missing side lengths in a pair of similar figures

- Use similarity to solve real-world problems
