In this game activity students practice comparing shapes and naming something that is alike or different about them.

These activities will allow students to discover the concepts of geometry through shape exploration and the creation of choreographic sequences.

In this lesson, students will explore self-portraiture by looking at classical portrait paintings, such as Diego Velazquez's La Infanta Margarita or Raphael's Portrait of Baldassare Castiglione. A close look at these works reveals mathematical relationships and proper proportions that students can incorporate into their own self-portraits.

What do students love more than building? Building with marshmallows! In this lesson, students get to build shapes with marshmallows and toothpicks. Included are an extensive lesson plan, a video showing examples, a worksheet, and ideas for centers.

Rhombus, the mathematically correct term for "diamond" is the focus of this interactive lesson.

Kindergartners love making things, and this activity allows them to create a unique shape monster and practice numbers recording the shapes used.

Clean Up this Mess! The classroom shapes are in one big heap. Students will work in teams to come up with a way to sort the shapes by attributes and create a visual representation to model their thinking. Pictures and videos of the lesson in action are included.

Identifying 2D shapes in common objects and sorting according to shapes connects the real world to learning shape names and attributes.

Kindergarteners love to identify shapes in their environment. In order effectively do that, they must be able to recognize different shapes by their specific attributes. In this lesson kindergartners learn about different types of triangles.

In this lesson students will explore shape sorting by attributes using a variety of media.

You will enjoy this shape game. It tells you the name of a shape and all you have to do is click on the correct shape. If you get confused you can have another try.

Practice comparing shapes based on their number of sides, number of corners, and side-lengths. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
