In this lesson, we will learn:

- How to describe common characteristics/attributes in groups of objects
- What the regions of the Venn Diagram mean in order to sort objects by their attributes
- The vocabulary "AND", "OR", and "NOT" within the context of Venn Diagrams

**Venn Diagrams**organize data by**sorting**by characteristics ("**attributes**")**Circles**are used to group objects by these characteristics- Objects
__inside__the circle have the attribute - Objects
__outside__the circle do NOT have the attribute - Objects with more than 1 attribute go into the
**overlapping**part of attribute circles they belong to - A large
**rectangle**surrounds all circles and objects, it represents all the objects

- Alphabet letters are given to objects to save space when sorting in the Venn diagram

- The vocabulary words "
**AND**", "**OR**", and "**NOT**" have special meanings for sorting: - AND = means must have both attributes
- OR = means having either attribute
- NOT = means not including
