Evidence of Learning:
1. Compute unit rates involving rational numbers, fractions, and
    complex fractions (e.g., 1/4 of 1/2).
2. Compute ratios of length in like or different units.
3. Recognize, represent and explain proportional relationships using
    tables, graphs, diagrams and verbal descriptions.
4. Identify constant of proportionality (unit rate) in tables, graphs,
    diagrams, and verbal representations.
5. Create and solve equations to represent proportional relationships.
6. Represent constant of proportionality.
7. Reproduce a scale drawing at a different scale.
