Match Fishtank 50 min(s)

In this lesson, students will multiply mixed numbers by whole numbers. Multiply a mixed number by a whole number using area models, tape diagrams, and/or number lines. Solve word problems that involve the multiplication of a mixed number by a whole number. Students learned how to multiply a mixed number by a whole number in Grade 4. However, this lesson is included to serve as a review before moving on to more advanced types of multiplication involving mixed numbers. This lesson includes various representations that students can use to multiply fractions. Because the area model is the best one for more complex computations like a mixed number times a mixed number, you should make sure students at least understand and can make use of that strategy.
