- 6.D:
- Represent and analyze proportional relationships using tables, graphs, equations, diagrams, concrete and mathematical models, and verbal descriptions of proportional relationships
- 6.E:
- Compute the constant of proportionality (unit rate) associated with rational numbers
- 6.F:
- Recognize and connect proportional relationships to geometry, measurement, statistics, probability, and function
- 6.G:
- Use ratio reasoning to convert measurement units
- 6.H:
- Apply ratio and proportion concepts to model real world situations
