Proportional Relationships

In this unit, students will be able to compute unit rates associated with ratios of fractions. Students will learn to analyze data to determine whether two quantities are proportionally related using a table, graph and an equation. They will be able to identify the constant of proportionality and generate an equation for proportional relationships. Using a graph, students will be able to identify and explain the unit rate (constant of proportionality) and what the points (0, 0) and (1, r) represent. Students will apply proportional relationships to solve multi-step ratio and percentage problems.
