Layers of Cubes
See one layer as the area of the base, then stack the layers.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 4
- The bottom layer sits right on the base of the box. The number of cubes in that layer matches the base's area.
- Add another layer, and there are 2 groups of 15.
- With 4 layers, the box is full. That's 4 groups of 15.
- We can write that as one expression. The parentheses show the layer, which we find first. Then we multiply by the number of layers.
Georgia's K-12 Mathematics Standards:
- 5.GSR.8.3 — Investigate volume of right rectangular prisms by packing them with unit cubes without gaps or overlaps. Then, determine the total volume to solve problems.
- 5.GSR.8.4 — Discover and explain how the volume of a right rectangular prism can be found by multiplying the area of the base times the height to solve authentic, mathematical problems.
