A fraction of a number, in two steps

Finding a fraction of a number combines dividing and multiplying. To find 2/3 of 9: divide by the denominator (9 / 3 = 3, the unit fraction), then multiply by the numerator (3 x 2 = 6). The most common error is stopping after the first step, so non-unit fractions need both moves.

How to use it

Teach it as divide by the bottom, multiply by the top. For a unit fraction like 1/4, only the divide step is needed. This builds on naming fractions of a shape and supports word problems involving parts of a group.

👩‍🏫 Teacher note

Two steps: divide by the denominator to find the unit fraction, then multiply by the numerator. For 2/3 of 9: 9 / 3 = 3, then 3 x 2 = 6.

🏠 Parent note

To find 2/3 of 9: divide 9 by 3 (that's 3), then multiply by 2 (that's 6).

Common Mistakes to Watch For

  • Multiplying by the denominator instead of dividing
  • Stopping after the unit fraction for a non-unit fraction
