Common mistakes
Misconceptions students bring to fractions
Specific errors to watch for when reviewing student work — pulled from classroom research and teacher reports.
Adding numerators and denominators directly.
What to teach instead: Find a common denominator first; only the numerators add.
1/2 + 1/3 ≠ 2/5. Convert to sixths: 3/6 + 2/6 = 5/6.
Believing a fraction with a larger denominator is always larger.
What to teach instead: With the same numerator, a larger denominator means smaller pieces.
1/4 < 1/2, even though 4 > 2.
Forgetting that mixed numbers and improper fractions are equal in value.
What to teach instead: 1¾ and 7/4 are the same number written two ways.
Inverting only one fraction when dividing.
What to teach instead: Keep the first fraction, flip the second, change division to multiplication.
2/3 ÷ 1/4 = 2/3 × 4/1 = 8/3.
Multiplying always makes a number bigger.
What to teach instead: Multiplying by a fraction less than 1 makes the result smaller.
10 × 1/2 = 5, which is less than 10.
