Common mistakes
Misconceptions students bring to percentages
Specific errors to watch for when reviewing student work — pulled from classroom research and teacher reports.
Confusing 'increase by 50%' with 'multiply by 50%'.
What to teach instead: An increase of 50% means multiply by 1.5; multiplying by 0.5 halves the value.
$100 increased by 50% is $150, not $50.
Thinking percentages can't exceed 100%.
What to teach instead: Percentages can be greater than 100 — they describe ratios, not just parts of a whole.
150% of 20 = 30.
Adding successive percentage changes directly.
What to teach instead: A 10% increase followed by a 10% decrease is not 0% — it's a 1% net decrease.
100 → 110 → 99.
