Grade 4 - Fractions - Subtracting Unlike Denominators with Modeling

In this video, the focus is on subtracting fractions with unlike denominators. The process begins by visually modeling the fractions using fraction bars. The demonstration highlights the necessity of finding a common denominator before performing the subtraction. By converting the fractions to have the same denominator, students can easily subtract and understand the process. The example provided shows how three-fourths minus one-half, once converted to have the same denominator, results in one-fourth.

This visual approach helps students grasp the concept of equivalent fractions and ensures they understand the need for common denominators when subtracting fractions.
