This Grade 3 worksheet introduces fractions on a number line using eighths and tenths. Students measure distance from 0, name unit fractions, and decide which tick matches a given fraction. Sentence-correction items fix mislabeled partitions, fill-ins reinforce unit fractions like 1/8 and 1/10, and true or false statements check understanding of denominators for Grade 3 learners. This printable is perfect for classroom warm-ups, homework, or math center rotations for Grade 3 fraction practice.

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 Grade 3 number line partitioned into 8 equal parts, the third tick from 0 is 3/10.
Rewrite: On a Grade 3 number line partitioned into 8 equal parts, the third tick from 0 is 3/8.
2. Fix the sentence:
A Grade 3 number line split into 10 equal parts shows the first tick is 1/8 from 0.
Rewrite: A Grade 3 number line split into 10 equal parts shows the first tick is 1/10 from 0.
3. Fix the sentence:
For Grade 3, the point 5/8 sits the same distance from 0 as 5/10.
Rewrite: For Grade 3, the point 5/8 sits farther from 0 than 5/10 on the same number line.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. On a Grade 3 number line from 0 to 1 split into eighths, the tick just before 1 is labeled 7/8.
2. A Grade 3 student partitions 0 to 1 into 10 equal parts; the point at the fourth tick is 4/10.
3. In Grade 3, the unit fraction used to partition a number line into eighths is 1/8.
4. On a Grade 3 number line in tenths, the point 6/10 is 6/10 units from 0.
Part C: True or False?
Read each statement. Circle True or False.
1. A Grade 3 number line partitioned into 8 equal parts uses the unit fraction 1/8.
True False
2. On a Grade 3 number line, 3/10 is farther from 0 than 7/10.
True False
3. In Grade 3, partitioning 0 to 1 into tenths creates 10 equal intervals.
True False
