Comparing and Ordering Fractions with Benchmark Fractions

The video tutorial introduces the concept of benchmark fractions and demonstrates how to use them to compare and order fractions. It explains the use of number lines as a visual tool for comparing fractions and ordering them from least to greatest. The lesson includes interactive practice where students draw number lines and compare fractions themselves. The tutorial concludes with independent exercises for students to complete on their own.

What is a benchmark fraction?

• A common fraction used to compare other fractions
