Understanding Fractions and Equivalents

Mrs. Smith teaches third graders about equivalent fractions using number lines. She explains how to divide number lines into fractions and create equivalence chains. The lesson covers why unit fractions get smaller as denominators increase and identifies fractions equivalent to one-half, one-third, two-thirds, one-fourth, and three-fourths. The video concludes with problem-solving exercises comparing fractions.
