This unit plan concentrates on the Ratios and Proportional Relationships domain of Common Core State Standards. Aspects of the Number System are also used in the study of ratios and proportional reasoning. Students will learn to analyze proportional relationships and use them to solve real-world and mathematical problems. Students will also apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers. This unit plan is designed to be completed in 10 days with 1-hour class sessions.

Use proportional relationships to solve multistep ratio and percent problems.
Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units.
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.
Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
Explain what a point (?, ?) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, ?) where ? is the unit rate.
