Comparing and Scaling the Next Unit

Dear Students and Parents,

The next unit in your child’s mathematics class this year is Comparing and
Scaling: Ratio, Proportion, and Percent. Students look at problems involving
many situations and learn to make comparisons using ratios, fractions, percents,
and rates.

UNIT GOALS

One goal of this unit is to develop students’ abilities to make useful comparisons
of quantitative information using ratios, fractions, decimals, rates, unit rates, and
percents. A second goal is to have students learn to use quantitative comparison
information to make larger or smaller scale models.  Students should also learn different ways to reason in proportional situations and to recognize when such reasoning is appropriate.
