This lesson previews the work of Grade 4 of developing an algorithm for finding equivalent fractions, but it also recaps every case of equivalent fractions students have seen thus far in the unit. Therefore, this lesson is optional though highly encouraged since it serves to summarize their work thus far as well as connect to future work on the topic.

1.
Partition the following area model into thirds. Then write a fraction to represent the whole.
Partition the following area model into sixths. Then write a fraction to represent the whole.
Partition the following area model into ninths. Then write a fraction to represent the whole.
2. What do you notice about the number of parts and the size of each part in each model in #1? What do you wonder?
