This Grade 3 worksheet builds plotting skills on unmarked number lines using CCSS 3.NF.2. Students figure out the denominator from the partition count, plot fractions like 2/5 and 3/4 by counting unit fraction jumps, and identify equivalent fractions. Fill-in and matching questions help Grade 3 learners connect 2/4 to 1/2, 3/6 to 1/2, and 3/3 to the whole, strengthening their fluency with fractions on a 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, if a number line from 0 to 1 has 5 equal parts, the denominator of each unit fraction is 5.
2. In Grade 3, to plot 2/5 on a number line, count 2 equal jumps of 1/5 from 0.
3. In Grade 3, a fraction equivalent to 1/2 on a line split into 4 equal parts is 2/4.
4. In Grade 3, a fraction equivalent to 1/2 on a line split into 6 equal parts is 3/6.
5. In Grade 3, the unit fraction on a number line partitioned into 8 equal parts from 0 to 1 is 1/8.
6. In Grade 3, to plot 3/4 on an unmarked number line, first partition 0 to 1 into 4 equal parts.
7. In Grade 3, a fraction equivalent to 1 on a line split into thirds is 3/3.
8. In Grade 3, on a number line split into 8 equal parts, the fraction 4/8 equals 1/2.
9. In Grade 3, to plot 2/3 on an unmarked line, split 0 to 1 into 3 equal parts, then count 2 jumps.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
