## MSTAR Interventions

### Outcomes

• Students will connect equivalent ratios to proportionality. (See Lesson 1.)
• Students will determine whether 2 ratios are proportional by using simplification. (See Lesson 2.)
• Students will determine the difference between additive and multiplicative thinking by using a table. (See Lesson 3.)
• Students will find missing values in a table, given a scenario that reflects multiplicative thinking. (See Lesson 4.)
• Students will find a missing value of a proportion by multiplying by the scale factor. (See Lesson 5.)
• Students will find the missing value in a proportion by using a unit rate. (See Lesson 6.)
• Students will determine whether 2 ratios are proportional by using common denominators. (See Lesson 7.)
• Students will find missing values in a proportion by using a common denominator. (See Lesson 8.)
• Students will identify patterns in using common denominators to find missing values in proportions as a foundation for using cross products. (See Lesson 9.)
• Students will determine whether 2 ratios are proportional by using cross products. (See Lesson 10.)
• Students will find missing values in proportions by using cross products. (See Lesson 11.)
• Students will determine the most efficient strategy for finding the missing value in a proportion. (See Lesson 12.)
• Students will write proportions in multiple formats from word problems. (See Lesson 13.)
• Students will write and solve proportions with missing values from word problems. (See Lesson 14.)
• Students will set up and solve proportions in application problems involving percents, using percent bars. (See Lesson 15.)
• Students will set up and solve proportions in similar figure application problems involving missing lengths. (See Lesson 16.)
• Students will make connections between tables and graphing and recognize proportional relationships, using graphs. (See Lesson 17.)
