Exploring Fractions on the Number Line

In this video, Mrs. Fredette introduces benchmark fractions, explaining their frequent use in everyday life. She guides students through plotting these fractions on a number line, demonstrating how to divide the line for fractions like 1/2, 1/3, 1/4, 1/5, 1/8, 1/10, and 1/100. The tutorial emphasizes understanding the relative sizes of these fractions and provides a hands-on activity for students to practice in their math journals.
