In previous lessons, students developed an understanding of how to find products of fractions both with an area context and with no context. The purpose of this lesson is to use this knowledge to solve problems about different national flags. Students work with problems where the side lengths are given and they are finding the area in square units of a particular region. They also solve problems where they are determining what fraction of the flag a certain region is. The distinction between these two types of problems is subtle, but is important as the answer to the first problem involves square units but units are not needed for the second problem.
- Solve problems involving multiplication of fractions.
- Let’s solve problems about flags.
