###### Topic Notes

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

Notes:

• 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
