⚠️ Common Mistakes & Teacher Fixes

⚠️Adding the Whole Number to the Numerator First

Why students stumble: Students calculate (Whole + Numerator) × Denominator (e.g. for 2 3/4 doing (2+3)×4 = 20/4 = 5).

Teacher Fix: Remember PEMDAS: Multiplication comes before addition. Multiply the bottom by the whole first, then add the top: (2 × 4) + 3 = 8 + 3 = 11/4.

Example: Incorrect: 2 3/4 ➔ (2+3)×4 = 20/4. Correct: 2 3/4 ➔ (2 × 4 + 3)/4 = 11/4.

⚠️Dropping the Original Denominator

Why students stumble: Writing just the converted numerator (e.g. writing '11' instead of '11/4').

Teacher Fix: Remember an improper fraction is still a fraction with a numerator and a denominator. The denominator is preserved from the original fraction.

Example: 2 3/4 = 11/4.
