Angle-a-trons (2:04)  Measure angles without a protractor!  A little too fast to show in class without support.  Try teaching the concept yourself, presenting it with supports, or sharing it in a place where students can repeatedly view it.

Surface Area of a Rectangular Prism  (4:42)  A visual explanation.  Great use of vocabulary; plenty of opportunities to add discussion about mathematical properties, algebraic thinking, and alternate solution pathways.

Area of a Circle Formula Explained(2:47)  A visual explanation.

Surface Area of a Cylinder (3:08)  A visual explanation.  Could your class use the rules of algebra to connect this explanation to the formula given on the GED formula sheet?

Pythagorean Theorem (2:37)  An interesting explanation a little beyond others that I have seen.
