This Grade 3 practice worksheet focuses on denominators and equivalent fractions on number lines, aligned to CCSS 3.NF.2. Students identify unit fractions from partition counts, find equivalent points on different denominators, and plot fractions on unmarked lines. Fill-in and matching questions help Grade 3 learners see how 2/6 equals 1/3, 2/8 equals 1/4, and 4/4 equals 1 on the number line.

Fractions on a Number Line
Part A: Fill in the Blank
Write the missing word or number on each line.
1. In Grade 3, a number line from 0 to 1 with 3 equal parts has unit fraction 1/3.
2. In Grade 3, on a sixths number line, a fraction equivalent to 1/3 is 2/6.
3. In Grade 3, a number line with 8 equal parts from 0 to 1 has 1/8 as its unit fraction.
4. In Grade 3, on a fourths line, a fraction equivalent to 1 is 4/4.
5. In Grade 3, on a sixths line, the fraction 3/6 is the same point as 1/2.
6. In Grade 3, to plot 3/5 on an unmarked line, first split 0 to 1 into 5 equal parts.
7. In Grade 3, the fraction at the third tick after 0 on a sixths line is 3/6.
8. In Grade 3, on an eighths line, a fraction equivalent to 1/4 is 2/8.
9. In Grade 3, the fraction at the second tick after 0 on a thirds line is 2/3.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Equivalent to 1/2 on a sixths line
→ 3/6
3/6
Equivalent to 1/4 on an eighths line
→ 2/8
2/8
Equivalent to 1/3 on a sixths line
→ 2/6
2/6
Equivalent to 1 on a fourths line
→ 4/4
4/4
