Topic_D_Ratios_of_scale_drawings

Topic D includes lessons 16-22 and covers relating scale drawings to ratios and rates, the unit rate as the scale factor, computing actual lengths from a scale drawing, computing actual areas from a scale drawing, an exercise in creating a scale drawing, and an exercise in changing scales.

Topic_B_Unit_rate_and_constant_of_proportionality

Topic B includes lessons 7-10 and covers unit rate as the constant of proportionality, representing proportional relationships with equations, and interpreting graphs of proportional relationships. (Currently, we do not have content for Lesson 10.)

Topic_A_Proportional_relationships

Topic A includes lessons 1-6 and covers an experience in relationships as measuring rate, proportional relationships, identifying proportional and non-proportional relationships in tables, and identifying proportional and non-proportional relationships in graphs.

Topic_C_Ratios_and_rates_involving_fractions

Topic C includes lessons 11-15 and covers ratios of fractions and their unit rates, finding equivalent ratios given the total quantity, multi-step ratio problems, and equations and graphs of proportional relationships involving fractions. (Currently, we do not have content for Lessons 11 and 14.)
