Tiling the Plane
Students use pattern blocks and triangular grid paper to review shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked: "Have you ever seen a floor or a wall...

Geometric Shapes at the OK Corral
Students explore geometric shapes. In this math lesson plan, students identify geometric and non-geometric shapes using the computer. Students research geometric shapes in art and architecture.

Geometric Shapes at the OK Corral
Students explore regular geometric shapes. In this shapes lesson, students investigate geometric shapes in the world around them. Students differentiate between regular and irregular shapes.

Angle Action
Students measure and label specified angles. In this angles lesson plan, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This...
