In this Illuminations lesson, students identify and classify polygons according to various attributes. They then sort the polygons in Venn Diagrams, according to these attributes.
Students will:
- precisely describe, classify, and understand relationships among types of two-dimensional objects using their defining properties
- use Venn Diagrams to sort polygons according to certain attributes
- understand and apply basic concepts of probability
