- Counts or computes (row by column by height) the number of cubes in one row, and then uses addition or skip counting to determine the totals.
- Computes (row times column times height) the number of cubes in one row, and then multiplies by the number of layers to determine the total.
Help your student become a(n) 3D Row and Column Structurer
Activities help children continue to develop spatial structuring–organizing objects in space such as cubes into rows, columns, and layers. Here, children might make one row of cubes in the bottom of a container, then skip count or multiply to figure how many rows will make one layer on the bottom. They then can skip count to figure out how many layers. Such thinking leads to, but is just as or more important than, learning a formula such as V = l * w * h.
