You start with one as a vertical trait (top to bottom) I.
For two you go to the right (L).
For three you go up (U).
For four you go left (and you get a square).
For five you go diagonal from top left to bottom right (the final result is a crossed square).
It has the advantage that you never need to lift the pen from paper until you get to five and with a little of practice you don't even need to look at the sheet until you actually need to calculate the sum of more than one tally.
