Students learn the definition of a polygon, as well as the definitions
of concave and convex polygons. Students also learn the following
polygon classifications: triangle (3 sides), quadrilateral (4 sides),
pentagon (5 sides), hexagon (6 sides), h...eptagon (7 sides), octagon (8
sides), nonagon (9 sides), decagon (10 sides), dodecagon (12 sides).[more]

The Polygon Song Video is a Shape Song Video that teaches the Polygons:
Triangle, Quadrilateral, Pentagon, Hexagon, Heptagon, Octagon, Nonagon,
and Decagon. These Shape Videos teach the Shape Names, Geometry Skills,
Math Vocabulary, Shape Recog...nition, and use Audio, Visual, and
Kinesthetic Learning. (04:03)[more]

This catchy tune from They Might Be Giants is about many sided polygons. It shows images of polygon shapes and how many side they have. Key vocabulary words include: pentagon, triangle, nonagon, and octagon. (01:22)

This short video is a great resource to teach polygons to your students. Pentagons (5 sides), Hexagon (6 sides), Hectagons (7 sides), Octagons (8 sides), Nonogans (9 sides), and Decagons (10 sides) are discussed in this video. Visuals accompany the ...song that shows the numbered sides. This catchy song will help students master this skill. (3:18)[more]

In this video, the instructor shows the viewer the different types of polygons based on the number of sides and angle measurement. The instructor uses computer software for instruction. Clear, step-by-step instruction.

A computer-generated animation, with lively musical
accompaniment. It whimsically explores the geometric relationship
between two regular polyhedrons, a cube and a dodecahedron.

Tim Bedley, veteran teacher, gives a mini lesson to remind students how to recognize a polygon. He uses an interactive board to illustrate how to recognize polygons. This is a great resource to introduce and/or to review polygons in the elementary cl...assroom. (1:40)[more]

This is a portion of a song by Obie Leff from his CD "Do Re Mi Geometry". The first few bars are sung to the tune of 'Mary Had a Little Lamb'. There are various shapes moving about on the screen as the song is sung. Lyrics scroll across the screen. (...1:15)[more]
