Learners use Geometer's Sketchpad to draw triangles and explore the classificaiton of each using the mearsures of interior angles and the lengths of the sides.

Students explore geometry by drawing various shapes in class. In this triangle characteristics lesson, students identify the attributes that classify a shape as a triangle and practice using their bodies to create triangles in class....

Fourth graders use dancing methodology in a polygon and shape activity. In this shape and dance lesson, 4th graders discuss shapes in dance, math, and everyday life. Students use dancing activities to recognize and analyze shapes.

Young scholars discover three lettered postulates that prove triangles congruent.

Third graders investigate congruent polygons through dance. In this congruency activity, 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...
