Comparing and Scaling
Make comparisons using ratios, fractions, decimals and more

In Comparing and Scaling, students learn to make comparisons through real-life situational problems. The main focus of this unit is to develop students’ abilities to make useful comparisons of information using ratios, fractions, decimals, rates, unit rates, and percents. An example of this would be “Which is less expensive, three roses for five dollars or seven roses for nine dollars?” Students will also learn different ways to reason in proportional situations and to recognize when such reasoning is appropriate.

For an in-depth explanation of goals, specific questions to ask your students and examples of core concepts from the unit go to Comparing and Scaling.
