Lesson objective: Practice rewriting mixed numbers as equivalent fractions to create flexibility when adding and subtracting. 

This lesson helps build procedural skill with adding and subtracting mixed numbers. Deliberate use of vocabulary is used here because it supports the connection between a whole and the equivalent fraction. This work develops students' understanding that replacing a mixed number with an equivalent fraction and using the relationship between addition and subtraction provides flexibility when adding and subtracting fractions with like denominators.

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they write equivalent forms of mixed numbers. Students will practice using fraction forms of mixed numbers to add and subtract mixed numbers. 

Key vocabulary:

  • fraction
  • mixed number
