Dividing Fractions and Visual Models

This video tutorial introduces Module 2, which focuses on division by fractions using visual models. The instructor explains the concept of dividing whole numbers by fractions and provides examples, such as dividing trail mix and frosting among groups. The video emphasizes understanding the meaning behind division rather than just following steps. Students are encouraged to use visual models and practice problems to reinforce their learning.
