Tally marks are a quick way to show numbers using lines. Every line represents one count. When we reach five, we draw four vertical lines and then a diagonal line across them.
Count each line one by one. Remember, a group of five is easier to spot quickly.
When numbers get bigger, we use groups of five to make counting faster. Each group of tally marks equals five, and then we add the extra marks if needed.
Say “five” for each group, then add the leftover marks.
Tally marks can show numbers all the way up to 20 and beyond. Each group of five helps us count quickly without needing to count each line one by one.
Group marks in fives to avoid mistakes. Count “5, 10, 15...” then add the rest.
Tally marks are used for keeping score, counting items, and recording quick notes. They help us organize numbers in an easy-to-read way.
Whenever you need to count quickly, use tally marks instead of writing the numbers every time.
