Do This and Grumpy Cat Smiles
Because Grumpy Cat knows how wrong this is, and yet it still works. He's so evil.
Can you develop your own version of this error?
.DoThis posters are a mildly humorous collection of common errors in the math classroom. The first ones -- the handwritten ones -- were by Bowman Dickson (@bowmanimal). I created some new ones and showed them to my classes and those classes created even more. Later ones were contributed by the #MTBoS.
We cleaned up the original images a bit and tried to keep it sensible, but between the kids' and my evil senses of humor, this project grew out of control. We ultimately decided that we might as well enjoy it.
Some middle school teachers thought the humor was too dark, so many of these now have less final outcomes.
