How to approach this skill

Problem: 2 2/3 + 1 1/3 = ___

Answer: 4

Strategy: Treat the denominator as the number of equal parts and the numerator as the number of those parts being used. This example supports the page objective: Add and subtract fractions and mixed numbers that share a denominator.

How to use this worksheet

  • Use fraction strips or number lines to connect symbols with quantities. For this add and subtract fractions with like denominators set, begin without a timer.
  • Have the learner state what the numerator and denominator mean in each problem. Regenerate only when the learner is ready for another arrangement of the same objective.

Begin with the easy setting when the strategy is new, use standard for independent practice, and reserve challenge for a learner who can explain the method accurately.

Common mistakes to watch

  • Comparing denominators as if a larger denominator always means a larger fraction. Watch for this specifically during add and subtract fractions with like denominators practice.
  • Adding or multiplying numerators and denominators with the wrong operation rule. Use the worked correction as the next teaching example.

Use the answer key to find a pattern, then ask the learner to explain one corrected example rather than repeating an entire set immediately.
