Open Up Resources 40 min(s)

The purpose of this lesson is to start the unit with an engaging activity where these arise naturally, in the scaling of flags and in questions about what percentage of the flag is taken up by a particular part of the design. In this unit students will be applying proportional relationships to solve problems with fractional ratios, rates, percents, and constants of proportionality. Learning targets: students remember how to compute percentages.
