Bats Triangular
 


Activity Overview

Students use manipulatives to construct a pyramid. The manipulative pyramid then becomes the basis students use to construct a pictorial representation of a pyramid. The TI-10 is used to show symbolic representation of students actions and also aids students in viewing the developing pattern.

Before the Activity
