tally marks

Tally marks are a way to count things using lines. Each group of five lines is called a 'tally group.'

You draw one vertical line (|).

You draw four vertical lines (| | | |) and then cross them with a diagonal line (\) to make a group.

You have 3 (| | |).

You have 2 groups of five (| | | | \ | | | | \).

A diagonal line represents the end of a group of five tally marks.

You can count groups of five and then add the extra tally marks.

There are 13 tally marks (5 + 5 + 3 = 13).

Tally marks help us count and keep track of numbers easily.

You draw 1 group of five (| | | | \) and 2 extra tally marks (| |).
