Lesson 11

Comparemos y clasifiquemos figuras sólidas

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.
