RP. 3) Given a proportional relationship represent it a variety of ways: . A table. Plotting points on a coordinate graph. . Tape diagrams. Double number line diagrams. 6. RP. 3 –Use ratios and rate reasoning to solve (single step)real world mathematical problems using the representations above and Using the unit rate c. See % as a rate 7. RP. 2. Using the representations from 6 th grade a. Decide whether two quantities are in a proportional relationship. b. Identify the constant of proportionality 7. RP. 3 Use proportional relationships to solve (multi-step) ratios and percent problems. d. Ratio reasoning and manipulating units by multiplying and dividing 7. RP. 2 c. Represent proportional 6 th graders are not asked to express proportional relationships algebraically relationships by equations. d. Understanding the proportional relationship on a graph most importantly (0, 0) and (1. r)
