Our counting system is based on groups of 10.

Numbers under 10, we call units.

When we reach 10 and more, we count how many groups of 10 there are, and what is left over will be our units.

If we have 10 groups of 10, we call that a hundred.

In the Deans counting system, we have a little cube to represent a unit. We have a rod the same length as 10 units, to represent the number 10, and we have large squares the same size as 10 rods side by side to represent the number 100.

If we have 2 large squares, 3 rods and 6 small cubes, this would represent the number 236. as displayed below.
