Dividing Whole Numbers by Unit Fractions with Visual Models

This video tutorial teaches how to divide whole numbers by unit fractions using models. It begins with a review of basic division concepts, using apples to illustrate dividing whole numbers into equal groups. The lesson then progresses to dividing whole numbers by unit fractions, such as halves and thirds, using apples and pizzas as examples. The video emphasizes understanding division vocabulary, including terms like dividend, divisor, and quotient, and demonstrates how to use models to visualize division problems.
