Similar Shapes

For Students K - 1st Standards
In geometry, similar and congruent shapes are often confused. Shapes that are similar are the same shape, but a different size. This activity gives young learners some practice in identifying similar shapes. There are five polygons...

What Does Congruent Mean?

For Teachers 6th - 12th
Two figures are congruent if they have the same size and shape. Line segments can also be congruent if they are of the same length. Vertical angles created by intersecting lines are always congruent. Polygons that have matching angles...

Congruent Polygons: Copying Stretchy Shapes

For Teachers 3rd
Third graders investigate congruent polygons through dance. In this congruency lesson, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Tiling the Classroom

For Teachers 5th - 7th
Students see how to identify regular polygons, how to slide, turn and flip polygons, and why certain polygons tessellate better than others. Groups create a one foot square design to be used to tile the classroom. Great lesson!

Transformations - Rotations in the Coordinate Plane

For Teachers 8th - 11th Standards
In this geometry lesson, math scholars brainstorm examples of rotations.  Using the SMARTboard, learners observe a rotation. They create their own rotation using graph paper. Finally, pupils complete a worksheet and graph rotations.
Lesson Planet

Visual Patterns in Tessellations

For Teachers 7th - 10th Standards
Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.
Lesson Planet

The Shape Show

For Teachers 1st - 2nd
Define plane shapes by their properties, then use this game to reinforce those skills. Learners use given properties as clues to determine each shape. They work to name ten different shapes, six of which are polygons.
Lesson Planet

Geometry and Measurement

For Teachers 8th - 10th
Scholars explore relationships between units of measure and objects to be measured. They develop an understanding of length, area, and volume. Finally, students identify and develop their spatial sense and apply appropriate techniques,...
