3
**Ten 1-cubes make a 10-stick.**

Start with a 1-cube. 10 Ten 1-cubes make a 10-stick. 1

4
**Ten 10-sticks make a 100-slab.**

5
100 10 Ten 100-slabs make a cube. 1 1000

6
**So there are a thousand 1-cubes in the 1000-cube!**

Ten 100-slabs make a cube. 1 So there are a thousand 1-cubes in the 1000-cube! 1000

7
**...then a thousand is this big…**

Watch how it builds up. × 10 10,000 100,000 If one is just this big… × 10 × 10 10 × 10 1 ...then a thousand is this big… 1,000,000 100 1,000 × 10 × 10 …and how big is a million?

8
One was just this big…. ….but a million won’t fit on the screen!

9
**× 10 × 10 × 10 First the one-cube builds up to …. …a thousand-cube.**

10-stick 1-cube × 10 × 10 100-slab

10
**Then the thousand-cube builds up to…**

…a million-cube. 1,000 1,000,000 × 10 × 10 1,000 1,000 10,000 1,000 1,000 1,000 Imagine the thousand-cube moving away, so it looks smaller and smaller…. × 10 × 10 100,000

11
**Then the million–cube builds up to…**

…a thousand million-cube. 1,000,000 1,000,000,000 × 10 × 10 1,000,000 1,000,000 10,000,000 1,000,000 1,000,000 1,000,000 × 10 × 10 100,000,000

12
**…a million million-cube!**

Then the thousand million-cube builds up to … 1,000,000,000 1,000,000,000,000 × 10 × 10 1,000,000,000 1,000,000,000 10,000,000,000 1,000,000,000 1,000,000,000 1,000,000,000 × 10 × 10 100,000,000,000

13
**× 10 × 10 × 10 × 10 And so on… …from cube… …to stick… …to cube…**

…to slab…

14
× 10 × 10 …to stick… …to cube… × 10 × 10 × 10 …to slab…

15
…to stick… Will it ever stop? …to cube… …to slab…

16
**The cycle goes on to infinity!**

…to stick… The cycle goes on to infinity! …to cube… …to slab…
