Lesson 11
Compare and Sort Solid Shapes
Lesson Purpose
The purpose of this lesson is for students to compare solid shapes.
Lesson Narrative
In previous lessons, students identified, described, and built solid shapes. In this lesson, students describe and compare the attributes of solid shapes. When describing and comparing shapes, students are not required to know or use language such as “faces”, “edges”, or “vertices”. Students may use their own language to describe these attributes, such as “sides,” “points,” or “corners.” If it is unclear what part of a shape a student is referring to, consider asking them to point to which part of the shape they are describing.
