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. Students 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.

This lesson has a Student Section Summary.

As you finish up this section, reflect on the norms and activities that have supported each student in learning math. List ways you have seen each student grow as a young mathematician throughout this work. List ways you have seen yourself grow as a teacher. What will you continue to do and what will you improve on in the next unit?
