Shape up your students' understanding of geometrical attributes with this hands-on math lesson. Students will gain a better understanding of how to describe a shape by the number of edges and vertices it has, rather than by its name.

Use this lesson to review three-digit addition strategies including base-ten drawings, number lines, and the standard algorithm.

Get out the measuring tape and head outside! In this lesson, students gather measurement data and build a model of the school playground.

Give your students a conceptual understanding of three-digit addition with this lesson focused on base-ten blocks and drawings.
