This Grade 3 worksheet introduces fractions on a number line using CCSS 3.NF.2. Students partition 0 to 1 into halves, thirds, fourths, and sixths, then identify each labeled tick as a unit fraction. Spot-the-mistake, fill-in, and true or false questions help Grade 3 learners build confident vocabulary around partitioning, equal parts, numerator, denominator, and unit fractions before plotting more advanced 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:
A number line from 0 to 1 cut into 4 equal parts shows thirds in Grade 3.
Rewrite: A number line from 0 to 1 cut into 4 equal parts shows fourths in Grade 3.
2. Fix the sentence:
The first tick after 0 on a line split into 6 equal parts is 1/3 in Grade 3.
Rewrite: The first tick after 0 on a line split into 6 equal parts is 1/6 in Grade 3.
3. Fix the sentence:
In Grade 3, cutting 0 to 1 into 2 equal parts gives fourths on the number line.
Rewrite: In Grade 3, cutting 0 to 1 into 2 equal parts gives halves on the number line.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. In Grade 3, a number line from 0 to 1 split into 3 equal parts shows thirds.
2. In Grade 3, the first tick after 0 on a line partitioned into 4 equal parts is 1/4.
3. In Grade 3, a number line split into 6 equal parts between 0 and 1 shows sixths.
4. In Grade 3, the unit fraction on a number line split into 2 equal parts is 1/2.
Part C: True or False?
Read each statement. Circle True or False.
1. In Grade 3, a number line from 0 to 1 cut into 4 equal parts shows fourths.
True False
2. In Grade 3, the second tick after 0 on a line split into 6 parts is labeled 2/3.
True False
3. In Grade 3, the unit fraction 1/3 sits one-third of the way from 0 to 1 on a line split into thirds.
True False
