Relate volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume.
Students will learn how to find the volume of right rectangular prisms by multiplying. You should also relay that volume is a generalization of area. Next, students will learn that volume is additive. That is, we can decompose solids, find their isolated volumes, then add to find the total volume. After that, students should learn how to find the volume of other solids, such as a ring, by dropping the object into a right rectangular prism partially filled with liquid, then computing the change in volume. Here's a video on that. Finally, give your students this challenge.
