Frequently Asked Questions
Why do we draw a slanting line across four tally marks?
Drawing a slanting line across four vertical lines makes a group of five, which helps us count large numbers quickly in fives without making mistakes.
What is the key in a pictograph?
The key tells us the exact number of items that each picture or symbol represents, such as one apple drawing standing for 5 real apples.
How is a bar graph different from a pictograph?
A pictograph uses little pictures to show data, while a bar graph uses solid rectangular bars of different heights to compare the amounts.
