If you find yourself around kids on a regular basis, consider putting math problems in front of them. Consider collecting those math problems, and taking a picture* of the ones that they mess up. If you do all that, and send it in to me, we’ll help build a database of student work that is unparalleled. It will be of immense use to students and teachers.

Send the messages to mathmistakes@gmail.com. We’ll send you a thank you note, and a free subscription to the Math Mistakes website.**

 

*If you don’t feel comfortable taking pictures of student work, or if your district has rules forbidding it, then consider taking a second to copy down their work and sending it in. 

** That’s a joke.
