- Pours one container into another to see which holds more.
- Pours one container into two others, concluding that one holds less because it overflows, and the other is not fully filled.
Help your student become a(n) Volume Filler
Activities develop early volume concepts by focusing on capacity–how much a container can hold–more than volume per se (the amount of space an object takes up). Filling a container with water can be understood initially as much as a one-dimensional measure (length–the water gets higher) than a three-dimensional measure, which is acceptable at this level, but discussions should emphasize capacity and volume language.
