About the Pictograph and Tally Marks Calculator
Tally marks count in fives: four strokes and a fifth across them, so totals are quick to add. A pictograph uses a symbol for a fixed number of items (the key); half or a quarter of a symbol shows a remainder.
For bar graphs and pie charts, use the pie chart and bar graph calculator.
The formula
number of symbols = count ÷ key
Worked example
Mangoes 15, key ● = 5
- 15 ÷ 5 = 3
- ●●● and tally 卌 卌 卌
