π What is a Bar Graph?
A bar graph uses bars of different lengths to represent data. The length of each bar corresponds to the value it represents. Think of it like building towers β the taller the tower, the bigger the number! π
- π Uses rectangular bars to show amounts.
- π The bars can be vertical (up and down) or horizontal (side to side).
- π’ The length of each bar shows the amount of something.
πΌοΈ What is a Pictograph?
A pictograph uses pictures or symbols to represent data. Each picture stands for a certain number of items. Itβs like using emojis to tell a story! π§Έ
- π§Έ Uses pictures or symbols to show amounts.
- π Each picture stands for a specific number of items.
- π¨ Makes data fun and easy to understand, especially for young learners.
