In this Grade 4 worksheet, learners use number-line jumps to multiply fractions by whole numbers. Each jump represents a unit fraction, so four jumps of 1/3 land on 4/3. Sentence completion, fill-in-the-blank, and short-answer tasks ask students to count thirds, halves, fifths, and eighths to confirm products. The set strengthens 4.NF.4 reasoning with engaging, clear models that connect counting jumps to multiplication clearly.

Multiplying Fractions by Whole Numbers
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Four jumps of 1/3 on a number line lands on 4/12.
Rewrite: Four jumps of 1/3 on a number line lands on 4/3.
2. Fix the sentence:
If we make 5 jumps of 1/4, we ends on the point 5/4.
Rewrite: If we make 5 jumps of 1/4, we end on the point 5/4.
3. Fix the sentence:
Two jump of 2/5 each lands on 4/5 of the number line.
Rewrite: Two jumps of 2/5 each land on 4/5 of the number line.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Starting at 0, four jumps of 1/3 land at 4/3.
2. Three jumps of 1/2 from zero finish at the point 3/2.
3. Six jumps of 1/8 along the number line end at 6/8.
4. Five jumps of 2/5 starting at 0 land on the number 2.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Describe the number-line picture for 4 x 1/3 and the final point.
I begin at 0 and make four equal jumps of 1/3. After the fourth jump I land on 4/3, which is 1 1/3.
2. How does a number line show that 3 x 2/4 equals 6/4?
From 0, I jump 2/4 three times. Each jump skips two fourths, so I land on 6/4, which equals 1 2/4.
