I believe that students need to take risks in the mathematics classroom: the risk to not know (yet), to make mistakes, to speak up when something doesn't make sense, to ask for support, etc. In my experience this creates the environment that allows students to learn. If we ask our students to take risks, shouldn’t we, the teachers and facilitators, do the same? I find it easier for my students to be vulnerable when I have modeled what that could look like.
