This is how I introduce a person to dozens:

I first count to 20-z for them and have them repeat. One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve (they always find this first part simple) followed by twelve-one, twelve-two... twelve-ten, twelve-eleven, twent-ze. (most people can do this, if they can't I have them repeat me one number at a time)

Then I show them how to write the numbers and introduce what other bases are while giving the examples of computers using base 2.

The next step is the count all the way to gross.

What input is there from others here?

How did you come up with that method? Did you try several ways and this one was the best? How did you measure that?richard.chasen wrote: This is how I introduce a person to dozens:
