This Instructional Activity is a part of the Lesson 4, Unit 3, Grade 6. This optional activity is an opportunity to practice the methods in this lesson to convert between cups and tablespoons. The conversion factor is given in the form of a unit rate, so students only need to decide whether to multiply or divide. They might, however, choose to create a double number line diagram or a table to support their reasoning. Several of the measurements include fractions, giving students an opportunity to practice multiplying mixed numbers by whole numbers and dividing whole numbers that result in fractions.
