Lesson objective: Analyze and compare 3D shapes based on measurable attributes.

This lesson helps to build fluency with comparing 3D shapes based on measurable attributes. 3D shapes are used here because it highlights the main idea of analyzing and comparing them based on attributes. This work develops students' understanding that 3D shapes can be compared based on their number of sides, vertices/corners and other measurable attributes.

Students engage in Mathematical Practice 3 and 7: Students look for similarities and differences between each 3D shape and also being able to present their argument and respond to arguments of others as they explore the students lunch and decide which shapes are 2D and 3D and explain why.
