This is a complete lesson for learning how to teach your students how to add, subtract, multiply and divide mixed numbers. These problems combine skills your students should already know; converting between mixed numbers and improper fractions and adding, subtracting, multiplying and dividing fractions.

For example, consider the problem 3 3⁄4 + 2 2⁄5. That looks pretty challenging! The first step is to convert the mixed numbers to improper fractions, so that the problem becomes 15⁄4 + 12⁄5. Next, since this is an addition problem, convert the fractions to have a common denominator: 75⁄20 + 48⁄20. Add the fractions: 75⁄20 + 48⁄20 = 123/20. Convert that back to a mixed number: 123/20 = 6 3⁄20.

This lesson includes a set of Guided Notes for understanding mixed numbers and improper fractions, two check-ins using Google Forms, a review package, and a matching activity.

The review package can be used for in-class practice or for homework. I recommend using the Guided Notes first to show students how to do these problems. The students can then use the check-ins and the review package to practice. The review package includes several different tools for practicing these problems.

For the Guided Notes, the students will use copies without the terms filled in, and you can teach using the Answers/Completed Work document. The matching activity is useful for enrichment or as an extra opportunity to practice.

Everything but the check-ins and part of the review package can be used as printouts or online through Google Classroom. The check-ins are only online. Part of the review package is only usable through print.
