Mistakes: everybody makes them; the key is what happens next.

In his #CMCS15  session, Making Math Mistakes and Error Analysis: Diamonds in the Rough session, Andrew Stadel (@mr_stadel, Divisible by 3, and Estimation 180) challenges us to make our thinking visible and to seize opportunities to deepen understanding.

• Math mistakes are a valuable window into student thinking
• Analysis of mistakes can help drive instruction, curb student misconceptions, and strengthen formative assessment.

How might we strength formative assessment to spur action?  Knowing is not enough.  What if we bright spot work found in the mistake to show something was going well?

Do we practice?  How often do we reflect on our struggles? Knowing what went well and where we struggled, how might we consider taking new tack in what we do next?

Do something different… It’s what happens next.
