Learning goals: Learning Goals • Explain what equivalent ratios mean in the context of paint mixtures. (Lesson 1) • Identify patterns in tables that represent proportional relationships. (Lesson 2) • Use a table to calculate unknown quantities in a proportional relationship. (Lesson 2) • Determine the constant of proportionality for a proportional relationship represented in a table and explain what it means. (Lesson 3) • Use the constant of proportionality to calculate unknown information in a table. (Lesson 3) • Justify whether a table represents a proportional relationship or not. (Lesson 3) • Explain that when the value of one quantity in a proportional relationship is 1, the other quantity is the constant of proportionality. (Lesson 4) • Write equations to represent proportional relationships. (Lesson 4) • Use an equation to solve problems involving a proportional relationship. (Lesson 5) • Write two equations that represent the same proportional relationship (`y=kx` and `x=\frac{1}{k}y`). (Lesson 6) • Justify whether a relationship is proportional or not by looking at the structure of an equation. (Lesson 7) Materials • Calculators
