#### The identification of geometric shapes is an important kindergarten math skill. This math lesson allows students to see that shapes are all around us, even in our food!

#### What do students love more than building? Building with marshmallows! In this lesson, students get to build shapes with marshmallows and toothpicks.

#### When a Line Bends...A Shape Begins is a great book to use to introduce 2-dimensional shapes. The students will be introduced to all of the basic 2-dimensional shapes and learn about the attributes of a triangle.

#### What is Round? is a great book to use to look at examples of circles. The students will learn what is means to be round and learn about the attributes of a circle.
