In Topic D, students compare volume in the same progression as that of weight in Topic C. In Lesson 13, they see that one container holds more rice than another by pouring the rice from the first container into a smaller empty one. “It is overflowing! The bowl holds more rice than the cup.” In Lesson 14, students explore how volume is conserved by pouring rice from a cup to a bowl, then to a tall container, and then back into the original cup. They discover that while the quantity of rice may look very different when poured into different size and shape containers, it remains the same amount. In Lesson 15, students count the number of small cups of rice within a larger amount. “The bowl holds 10 little cups of rice. I wonder how many little cups of rice this mug holds?” Before the Mid-Module Assessment, students consider the different measurable attributes of single items such as a water bottle, dropper, and juice box. They consider what tools they might use to compare those attributes.
