## Read the story

How many cubes are in this building?

We count layer by layer, from the bottom up.

There are 4 cubes at the bottom and 2 on top. That makes 6.

**6 at the bottom, 3 in the middle, 1 on top: how many cubes?**

## Answer and working

Correct! 6 plus 3 plus 1 is 10 cubes.

`6 + 3 + 1 = 10`
