About the Mathematics in This Unit
| Benchmarks/Goals | Examples |
|---|---|
| Use standard units to measure volume. |
What is the volume of the cube?
All the edges of the cube are the same length: 6 cm. The base of the cube is 6 × 6, so 36 centimeter cubes would fit on the bottom of the box. Since the cube is 6 centimeters high, there are 6 layers in the box. 6 × 36 = 216. The volume of the cube is 216 cubic centimeters (216 cm3). |
In our math class, students spend time discussing problems in depth and are asked to share their reasoning and solutions. It is important that children solve math problems in ways that make sense to them. At home, encourage your child to explain his or her math thinking to you. Please look for more information and activities about Prisms and Solids that will be sent home in the coming weeks.
