Common Core For Grade 4

Examples, solutions, and videos to help Grade 4 students learn how to reason using benchmarks to compare two fractions on the number line.

Common Core Standards: 4.NF.2

Lesson 12 Concept Development

Problem 1: Reason about the size of a fraction compared to 1/2.

Problem 2: Plot points on a number line by thinking about fractions in relation to 0, 1/2, or 1. Compare the fractions.

Problem 3: Use the benchmarks 0, 1/2, and 1 to compare two fractions without using a number line.

Lesson 12 Benchmarks

What is a “benchmark” in learning about fractions?

Lesson 12 Problem Set 1

- a. Plot the following points on the number line without measuring.

i. 1/3

ii. 5/6

iii. 7/12

b. Use the number line in Part (a) to compare the fractions by writing <, > or = on the lines:

i. 7/12 ____ 1/2

ii. 7/12 ____ 5/6 - a. Plot the following points on the number line without measuring.

i. 11/12

ii. 1/4

iii. 3/8

b. Select two fractions from Part (a), and use the given number line to compare them by writing <, > or =. - Compare the fractions given below by writing < or > on the lines.

Give a brief explanation for each answer referring to benchmark fractions 0, 1/2, and 1.

a. 1/2 ___ 3/4

b. 1/2 ___ 7/8

c. 2/3 ___ 2/5

d. 9/10 ___ 3/5

Lesson 12 Homework

- a. Plot the following points on the number line without measuring.

i. 5/12

ii. 3/4

iii. 2/6

b. Select two fractions from Part (a), and use the given number line to compare them by writing > ˂ or =.

c. Explain how you plotted the points in Part (a). - Compare the fractions given below by writing > or < on the lines.

Give a brief explanation for each answer referring to benchmark fractions of 0, 1/2, and 1.
