Dividing Whole Numbers by Fractions

This lesson teaches how to divide whole numbers by fractions using models. It starts with unit fractions, explaining the concept with examples like dividing five by one-third. The lesson then progresses to non-unit fractions, using real-life scenarios such as Keith's bicycle race and Sabrina's pizza party to illustrate the process. By the end, students learn to apply these concepts to solve practical problems.
