Interpret tally charts
Key Notes:
What is a Tally Chart?
- A simple way to collect and record data (information) about things.
- Uses marks (usually straight lines) to show how many times something happens or how many people choose something.
Making Tally Marks:
- One item is shown by one straight line:
/ - When you reach five items, you draw a diagonal line across the previous four:
\//(This makes it easy to count in groups of five).
Counting Tallies:
- Count each group of
\//as five. - Count any single lines after the group of five as ones.
