problem_activity: Narrative
This warm-up prompts students to compare four representations. The reasoning here prepares students to connect the previous multiplication work to the division work of this lesson. It gives students an opportunity to use precise terms such as “factors,” “product,” and “quotient” in making comparisons (MP6). During the synthesis, ask students to explain the meaning of any terminology they use.

Activity Synthesis
“What equation can each diagram represent?” (The array represents
\(4\times6=24\)
because there are 4 rows of 6 dots, and there are 24 dots in the array. The area diagram could represent
\(4\times7=28\)
or
\(28\div4=7\)
since the sides are 4 and 7, and the area is 28. The tape diagram could represent
\(24\div3={?}\)
or
\(3\times{?}=24\)
because we know the total is 24 and there are 3 groups, but we don’t know how many are in each group.)
