Essential Understandings
Concrete:
- Use unit cubes to fill one layer (base) of the rectangular prism.
- Use the unit cubes to find the area of the base layer.
- Determine the number of layers needed to fill the rectangular prism.
- Use the area of the base and the number of layers (height) to find the volume of the rectangular prism by multiplying or using repeated addition.
- Recognize the formula for finding volume: V= l × w × h.
- Relate the concrete model to the formula V= B × h; where B = area of the base.

Cluster:
Geometric measurement: understand concepts of volume and relate volume to multiplication and to addition. (Major Cluster) : Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters. |
