Quick overview

This free fraction division worksheet for grades 5-6 teaches the keep-change-flip method with clear steps and practice problems.

Lesson plan snapshot

15-20 min
  • Warm-up (3 min): review reciprocals and fraction multiplication.
  • Model (5 min): solve the worked example using keep-change-flip.
  • Guided practice (5 min): complete problems 1-3 as a group.
  • Independent practice (7 min): finish the remaining problems.

Materials: fraction bars, pencil

Learning targets

  • Divide fractions by multiplying by the reciprocal.
  • Apply the 'keep-change-flip' method accurately.
  • Understand division as 'how many fit' or 'sharing equally.'

Step-by-step approach

  1. 1Keep the first fraction exactly as it is.
  2. 2Change the division sign to multiplication.
  3. 3Flip the second fraction (find its reciprocal).
  4. 4Multiply across and simplify.

Common mistakes

Mistake

Flipping the first fraction instead of the second.

Try instead

Only flip the divisor (the number after the ÷ sign).

Mistake

Flipping both fractions.

Try instead

Keep the first, flip only the second. Remember: Keep-Change-Flip.

Mistake

Dividing straight across like multiplication.

Try instead

Division requires the flip step. Dividing numerators and denominators separately doesn't work.

Worked example

Guided
Solve: 23÷14=?\frac{2}{3} \div \frac{1}{4} = ?
÷
  1. Keep: 2/3 stays the same.
  2. Change: ÷ becomes ×.
  3. Flip: 1/4 becomes 4/1.
  4. Multiply: 2/3 × 4/1 = 8/3.
  5. Convert if needed: 8/3 = 2 2/3.
Answer: 8/3 or 2 2/3

Teacher tips

  • TStart with 'how many fit' problems: How many 1/4s fit in 2?
  • TUse number lines to visualize division by unit fractions.
  • TConnect to real situations: cutting ribbon into 1/2 foot pieces.

Parent tips

  • PUse the phrase 'keep-change-flip' as a memory aid.
  • PPractice with simple cases first: 1 ÷ 1/2 = 2 (two halves in one whole).
  • PAsk 'does the answer make sense?' - dividing by a small fraction gives a big result.
