Applications of Ratios and Rates

Length 10 days

· Use various strategies to determine whether two quantities are proportional (e.g., by constructing a rate table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin).

· Solve problems involving scale drawings of geometric figures.

· Reproduce a scale drawing at a different scale.

· Compute unit rates with ratios of fractions including ratios of lengths, areas, and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.

· Identify the unit rate (constant of proportionality) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

· Explain what a point (
