Understanding Fractions and Models

This video tutorial teaches how to identify whole numbers using models and number lines. It begins with a review of fractions, explaining the roles of numerators and denominators. The tutorial covers cases where the numerator is greater than the denominator, using models like groups, length models, and number lines to illustrate these concepts. By the end, viewers will understand how to represent whole numbers with fractions using various visual aids.

What is the main focus of this lesson?
