This Grade 3 number line worksheet asks students to mark fractions like 2/4, 3/6, and 2/3 on lines already partitioned into equal parts. Using CCSS 3.NF.2, learners count numerator jumps from 0 to locate each fraction. Spot-the-mistake, fill-in, and true or false questions reinforce how 3/6 equals 1/2 and how 4/4 equals 1, helping Grade 3 students connect fractions to specific points on the number line.

Fractions on a Number Line
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
On a line split into 4 parts in Grade 3, the point 2/4 is at the first tick after 0.
Rewrite: On a line split into 4 parts in Grade 3, the point 2/4 is at the second tick after 0.
2. Fix the sentence:
On a line split into 6 parts in Grade 3, the point 3/6 is right at 1.
Rewrite: On a line split into 6 parts in Grade 3, the point 3/6 is right at 1/2.
3. Fix the sentence:
In Grade 3, marking 2/3 on a line split into thirds puts the point just before 1/3.
Rewrite: In Grade 3, marking 2/3 on a line split into thirds puts the point just before 1.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. In Grade 3, on a number line split into 4 equal parts, the point 2/4 is the second tick after 0.
2. In Grade 3, on a line split into 6 equal parts, the fraction 3/6 is the same point as 1/2.
3. In Grade 3, on a line split into 3 equal parts, the point 2/3 is the second tick after 0.
4. In Grade 3, on a line split into 4 equal parts, the point 4/4 is the same as the number 1.
Part C: True or False?
Read each statement. Circle True or False.
1. In Grade 3, on a line split into 6 parts, the point 3/6 lands exactly at 1/2.
True False
2. In Grade 3, on a line split into 4 parts, the point 3/4 sits closer to 0 than to 1.
True False
3. In Grade 3, on a line split into 3 parts, the tick labeled 3/3 is the same point as 1.
True False
