Lesson 3

Attributes that Define Shapes

Lesson Purpose

The purpose of this lesson is for students to describe geometric attributes of shapes.

Lesson Narrative

Students ask yes or no questions about geometric attributes to identify a “mystery quadrilateral.” Students will need their quadrilateral cards from the previous lesson to hide in the mystery quadrilateral folder and will have access to the quadrilaterals in their workbook to support them in questioning, guessing, and ruling out quadrilaterals in the table. Also, it may be helpful to provide counters that students can use to cover quadrilaterals that they rule out with their questioning.
