In this lesson, your students will become familiar with shapes by identifying them in real life. Your students will love identifying how many sides shapes have by drawing and counting them!

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.

Students sketch base-ten blocks in this lesson that builds both number sense and fluency adding to 20!

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.

It's time-telling time with this fun lesson featuring Trudy Harris' 'The Clock Struck One.' Students will learning about time with a short story and hands-on practice with analog clocks.
