Children need to move from the manipulative expressions of the distributive property into the mathematical equations eventually. This lesson is the first step in leading them to that goal.

The children have been practicing decomposing areas and now digits in order to understand and use the distributive property.

Students develop their understanding of the importance of different 2-dimensional shapes by finding real world examples.

Creating their own building is a hands-on, minds-on way for students to explore how polygons create 3D solids.

Hexagons are tricky! So close to stop-sign octagons, yet far less common. Plenty of practice is provided here.

This lesson is a real world task that combines many skills the students have learned throughout the school year.

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 the attributes of a square.

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 the attributes of a cone.

First graders begin to learn about plane shapes in Kindergarten. This lesson will serve as review of plane shapes' characteristics and extend into practice in categorizing shapes by defining attributes.

A big word for a big idea! After being introduced to the term quadrilateral, the students will learn the characteristics of them and have an opportunity to create various quadrilaterals.

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 the attributes of a square.

My first graders have been studying the defining attributes of 2D shapes. They are going to love using toothpicks and marshmallows to present their knowledge of 2D and create 3D shapes.

Students will get plenty of experience with hands-on practice and an opportunity to create an example of something shaped like an oval.

Interacting with polygons and testing the definitions can be engaging, fun and build a powerful, individualized understanding.

Practicing math problems to prepare for a geometry assessment involving volume and surface area.

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