I believe that mathematics should be taught, not collaboratively explored; algebra and geometry are better than a vague course of Integrated Math; spiraling doesn't work nearly as well as learning it properly the first time; "I don't DO math" should be an incentive rather than an excuse. "I don't DO English" should be treated the same way.

Factor Diagrams
Factor diagrams have been making the rounds and I was struck by this one from Brent:
Is it just me or should the diagrams for 15 and 45 be a blue pentagon with surrounds?
Was thinking the same thing, but it appears we are working outward with smallest factors first.
ReplyDeletePretty awesome though. Missed it the first time so thanks for blogging about it!
