Adding Fractions Using Area Models

The video tutorial explains how to use area models to add fractions. It starts with adding fractions with the same denominator by shading parts of identical figures. Then, it covers adding fractions with different denominators by adjusting the models to have the same number of parts. The tutorial concludes with a summary of the method using visual models.

What does it mean for two area models to be equivalent when adding fractions?

Describe the process of shading the parts in the new model after adjusting the area models.
