Tally marks are a quick way of keeping track of numbers in groups of five.
One vertical line is made for each of the first four numbers; the fifth
number is represented by a diagonal line across the previous four.
Thank you very much for the Tally font and especially the formula to translate regular numbers into tally marks. I am a 4th grade teacher and needed to both demonstrate the tally marks as a ways of collecting and recording data and the actual value of the tally marks to create charts.
