## Sorting

A Venn Diagram is a diagram using circles or other shapes, to show the relationship between sets.

## Types of Graphs

**Circle Graph**

A circle graph is shaped like a circle. It is divided into fractions that look like pieces of pie, so sometimes a circle graph is called a pie graph. Many times the fractional parts are different colors and a key explains the colors.

**Pictograph**

A pictograph uses pictures or symbols to show the value of the data.

**Bar Graph**

A graph drawn using rectangular bars to show how large each value is. The bars can be horizontal or vertical.

**Double Bar Graph**
