 Lesson Plan ID: 23976 Title: Comparing Fuel Economy (adapted from CMP "Comparing and Scaling" Investigation 4.1) Overview/Annotation: In this lesson students will explore rates. They will use the concept of rates to compute and compare fuel economy.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2019 (2019) Grade: 4 3. Determine and justify solutions for multi-step word problems, including problems where remainders must be interpreted. a. Write equations to show solutions for multi-step word problems with a letter standing for the unknown quantity. b. Determine reasonableness of answers for multi-step word problems, using mental computation and estimation strategies including rounding. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.1 Solve one-step word problems involving real-life situations using the four operations within 100 without regrouping and select the appropriate method of computation when problem solving. Mathematics MA2019 (2019) Grade: 7 1. Calculate unit rates of length, area, and other quantities measured in like or different units that include ratios or fractions. Alabama Alternate Achievement Standards AAS Standard: M.AAS.7.1 Calculate a unit rate (limited to whole numbers under 100). Mathematics MA2019 (2019) Grade: 7 2. Represent a relationship between two quantities and determine whether the two quantities are related proportionally. a. Use equivalent ratios displayed in a table or in a graph of the relationship in the coordinate plane to determine whether a relationship between two quantities is proportional. b. Identify the constant of proportionality (unit rate) and express the proportional relationship using multiple representations including tables, graphs, equations, diagrams, and verbal descriptions. c. Explain in context the meaning of a point (x,y) on the graph of a proportional relationship, with special attention to the points (0,0) and (1, r) where r is the unit rate. Alabama Alternate Achievement Standards AAS Standard: M.AAS.7.2 Use a ratio to model or describe a real-world relationship.
