Day 17: Why we WhiteboardPosted: September 19, 2013
My colleague Ben shared this awesome mistake with me today. This is why we Whiteboard; I don’t know that a single person would have guessed a student would make this mistake without the significant formative assessment that is whiteboarding.
Note that the problem was a written description, as shown at the top of the note, and the mistake is everything below that. Consistent!
