In the context of growth mindset, this post is about teachers also having a growth mindset about their students. I frequently hear something along the lines of, "How intelligent are my students?" I propose to permute the words.

If you don't know specifically what your students are good at, then it's time to start giving them more opportunities to do math in a way that let's you see how they think. Perhaps try a think-pair-share or get students to work in groups on a couple of problems, and go and visit.
