Comparing Fractions Using Benchmarks

This video tutorial for fourth-grade students covers Module 5, Lesson 12, focusing on using benchmarks to compare fractions. The lesson emphasizes understanding fractions through benchmarks like zero, one-half, and one, rather than relying solely on algorithms. Students learn to plot fractions on a number line and compare them by their relative positions. The tutorial includes examples of comparing fractions using these benchmarks and encourages students to develop reasoning skills. The lesson concludes with a summary of key concepts and a reminder that students will eventually use standard algorithms for comparison.

What is the primary focus of using benchmarks to compare fractions in this lesson?

• To develop an understanding of fractions

• To learn division

• To memorize algorithms

• To practice multiplication

Which benchmarks are used to compare fractions in this lesson?

• 0, 1/2, and 1

• 0, 1/4, and 1

• 0, 1/3, and 1

• 1/3, 1/2, and 1

If a fraction is close to 1, where would it be placed on the number line?

• Near 1/2

• In the middle

• Near 0

• Near 1

Where would 1/5 be placed on the number line using the benchmarks?

• Near 0

• Near 1/2

• Exactly at 1/2

• Near 1

How is 5/8 compared to 1/2 using benchmarks?

• 5/8 is less than 1/2

• 5/8 is equal to 1/2
