Tukey Tallying

(toc) #title=(Table of Content)

John Tukey invented it.

This is a method similar to Tally Marks, but it counts to 10 in one little diagram:

So, you start with one dot (for 1), then add dots as corners of a square until 4, then join the dots with lines until 8, then draw a diagonal each to make 9 and 10.

Then you can start another diagram for 11 onwards, like this:

Example: A dot tally of 12:

12

Example: A dot tally of 27:

27

The Traditional Tally Method

But most people use the traditional Tally Marks as they are a little quicker.
