Using Fraction Models to Represent Products of Whole Numbers and Fractions

The video tutorial covers the basics of fractions, explaining how they represent parts of a whole and can be visualized in various ways. It introduces multiplication, highlighting its properties and how it can be seen as repeated addition. The tutorial then explores multiplying fractions by whole numbers, using models and number lines to illustrate the process. Finally, it provides practice exercises using area models and number lines to reinforce the concepts learned.
