Exploring Fractions on a Number Line

Miss Hazal reviews fractions with her third-grade class, explaining the concepts of numerators and denominators. She demonstrates how to find fractions on a number line, focusing on 1/4, 3/4, 1/3, and 2/3. The lesson includes interactive elements where students identify fractions on a number line. The session concludes with a brief preview of future lessons on more complex fractions.
