Talk Math How do tally marks help you organize data?
Answer: Tally marks represent numbers they can count and say, but may not yet be able to write, and they are useful for keeping track of data collected by counting.

The tally marks are important as we mainly use them to keep the record of a running or continuous count. These marks are so useful for recording and maintaining the scores in a game or a sport.

Tally charts are used to collect data quickly and efficiently. Filling in a chart with marks representing numbers is faster than writing out words or figures and the data is collected into sub-groups immediately, making it easy to analyze.
