Setting the Stage With Geometry
Get your class thinking about geometry in their own bedrooms! Solving geometry challenges, individuals match words and definitions, find perimeter and area in their homes (rectangular, circular, and triangular), find circumference and area of welcome mats, use formulas to find surface areas and volumes of 3D shapes, and use a calculator to calculate the height of a can using the cylinder formula.

Carrying a Figure onto Itself
Your geometry learners will be pros at transforming figures using rotations and reflections after this hands-on lesson. Collaborative groups, with access to geometric construction tools, analyze and report the series of reflections and rotations that were used to produce an image from its pre-image.

Garden Variety Geometry
A home improvement plan can help adult learners preparation for the GED exam. They review vocabulary, prepare diagrams, complete a worksheet, calculate perimeters and analyze how to approach a story problem. They identify many geometry concepts used in solving GED problems.
9th - Higher Ed Math
Working in pairs, geometry students will construct a dilation and consider the properties associated with the similar figures that are created to verify the properties of dilation. This activity can be done using dot or graph paper and rulers, compasses, and protractors, geoboards, or dynamic geometry software.
