Mistakes aren't just okay, they are gifts!
Six years ago, I was attending some amazing professional development as part of the West Cook Math Initiative- now called Metro Chicago Math Initiative. We had a frequent guest facilitator, David Foster, leading us in a math talk and then discussing re-engagement lessons. I will never forget the day that he said, "Mistakes are gifts." In fact, I believe he said he had heard this from a teacher in Japan that was explaining the role that mistakes can play in helping students understanding mathematical concepts.
Bottom line, I don't know who to give credit to for this quote, but it certainly has had an impact on me. It is something that I repeat to students that I teach, teachers that I coach, and participants in professional development that I lead. I just can't say it enough!
Here's my vlog of my reflections on this idea:
If you like the idea of using mistakes in your classroom, consider re-engagement lessons as an alternative to "reteaching." You can read more here!
