Does chaos ensue when your students subtract like mixed numbers and the larger fraction has a lesser numerator? Using this lesson plan, teach your class how to overcome this tricky obstacle: When having like denominators isn’t enough!

Students will learn to model mixed number subtraction with manipulatives using this hands-on lesson plan.

Students will practice mental math and harness their discussion skills through addition problems of like mixed numbers. This lesson may be used on its own or as support for the lesson Adding Mixed Numbers Using the Decomposition Strategy.

Teach your students to add and subtract fractions with like denominators using a strategy that works for both operations: converting mixed numbers into improper fractions and back again!
