A great hands on activity with NO PREP time that reinforces the drawing and identifying of three-dimensional shapes. This lesson also brings to life a real world link with geometry. This resource is wonderful for middle school and high school and can even be a great lesson for those days you do not have time for a sub plan!

Beginning Geometry, Identifying 3D Shapes, Using a ruler
to see state-specific standards (only available in the US).
Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
