- Take out the hundred square, place it to the left of the ten bar, with the wires vertical. "This is a hundred."
- Using the ten bar, count over the tens in the hundred square. "Let's see how many tens there are in a hundred. One ten, two tens, three tens... There are ten tens in a hundred."
- Take out the thousand cube, place it to the left of the hundred square with the wires vertical to the mat. "This is a thousand."
- Take the hundred square and count the hundreds in the thousand cube. Go from bottom to top. "Let's see how many hundreds there are in a thousand. One hundred, two hundreds, three hundreds... There are ten hundreds in a thousand."
