Multiplying fractions by whole numbers: a worked example (3/8 × 2)

- Keep the denominator: 6/8.
- Simplify: 6/8 = 3/4.
How to use it at home and in class
At home
Ask your child to draw the first few as groups of bars: 3/8 × 2 is two bars with 3 eighths shaded on each. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Multiplying the denominator by the whole number as well.
- Leaving an improper answer like 15/4 instead of 3 3/4 when a mixed number is asked for.
What to practice before and after multiplying fractions by whole numbers
- Before: multiplying fractions. If this sheet is a struggle, go back a step.
- After: dividing fractions and whole numbers, once this one is mostly right.
- Learn it first: the multiplying fractions by whole numbers lesson and the fractions chart.
