Add and subtract mixed numbers
When to use this goal
For students who add and subtract simple fractions but drop the whole number, forget to regroup a whole, or subtract the smaller fraction from the larger regardless of order. Present levels in fraction addition and in mixed number conversion should be secure.
- Baseline
- Score problems that need regrouping (3 1/4 minus 1 3/4) separately from those that do not; the regrouping case is the usual failure. Decide whether answers must be simplified and apply the rule consistently.
- Tips
- Accept either method (improper fractions throughout, or whole numbers and fractions separately) unless the class requires one. Recipe and measurement contexts fit this skill well.
- Limits
- Multi-step problems mean several places to err; keep error notes with the score. Does not measure multiplication or division of mixed numbers.

Goal
By the annual IEP review date, given 10 addition and subtraction problems with mixed numbers and like denominators, including subtraction that requires regrouping a whole, the student will write the correct sum or difference for each problem independently with at least 80% accuracy on mixed number problems, on 3 of 4 consecutive weekly work samples, as measured by work-sample analysis collected weekly.
Baseline: 25% accuracy.

- Score only items the student attempted unless the goal defines a fixed set of items. Use the same denominator every session.
- Percent = numerator ÷ denominator × 100. Round to one decimal place.
- Record the support actually provided, even if the goal is independent performance.
