Snyder, C9, Consumption and creation with youtube and screencastomatic

For consumption of information I showed my students a clip from Khan Academy http://www.youtube.com/watch?v=kqqmJiJez6o on area of rectangles and triangles as an intro to the unit. For creation I made a Screencast-o-matic for my sub to use during my absence today. http://www.screencast-o-matic.com/watch/clehnMA1w
