Adding and Subtracting Fractions Challenge

In this video tutorial, the teacher introduces fifth-grade students to adding and subtracting fractions. The lesson is divided into sections, starting with an explanation of equivalent fractions and how to find them. The teacher then demonstrates how to add and subtract fractions with different denominators using equivalent fractions. Students are given practice problems to solve on their own, followed by a discussion of mixed numbers and an extension problem to be explored in the next class.

What is the first step when the denominators of two fractions are different?

• Find the least common multiple

• Add the numerators directly

• Convert them into equivalent fractions with a common denominator
