Back from a few days in Minneapolis at Twitter Math Camp and thinking about getting ready for next year. Twitter Math Camp is a grassroots conference organized by mathematics teachers and draws a pretty neat group of teachers from across the country (apparently, it was supposed to be a cruise at first).

Here’s what I’m thinking about now:

**1. Addressing knowledge gaps through differentiation:** I attended a morning session that ran over 3 days run by Park Star about how to address gaps in students’ existing mathematics knowledge. My big takeaway was that I need to figure out exactly what my goals are for my kiddos. Once those are established, I need to go back and figure out what they should have learned beforehand in order to access that content. Rather than pre-assessing the material we’re going to teach (but, um, haven’t), we should pre-assess the material kiddos should have learned and then differentiate support before the unit begins so that all students have access to what we’re learning. This feels especially relevant since so many of our kiddos come to us with gaps and different understandings from their home countries. Park Star also did a great job setting up the session – there were a ton of interactive strategies that also gave people think time. Probably stealing most of them for my class.

**2. Mathematics identities:** I went to a session by Nicole Bridge about students’ mathematical identities, which is something I’ve been finding myself pondering lately.

Big takeaways:

- Identity is COMPLEX (sorry, but not really, for the all caps).

2. One can have multiple identities at once.

3. A mathematics identity comes from what a person thinks of their ability to do mathematics as well as how others perceive and treat them

(*these are largely paraphrases of a quote from Danny Martin, link to citation, albeit not to actual paper here). I’m still mulling 0ver how to talk about this with my students, but I think even talking about these 3 ideas could be both new and productive to them.

3. **How do we revise the Common Core State Standards?**: I attended a session with Henri Picciotto about changes to the Common Core. Something I’m taking away from other conferences I’ve attended is to think about the Common Core State Standards and how they progress from kindergarten to 12 grade (this also ties in nicely to Tracy Johnston Zager’s keynote about elementary and secondary teachers collaborating). I’m planning to think more about which standards to focus on (we rarely get through all of them). Henri points out that we don’t currently have a plan to revise the standards (Henri’s thoughts are here, which seem like a great starting point). They are a great starting point, but, like all things, they can be better. There seems to be consensus that the standards need to be revised (although this is an assumption, perhaps a big one), but by who, when, and how all seem to be more nebulous. Wondering if anyone else has any ideas or insights here…

4. **Social Justice and Mathematics have similar themes**. I loved Jose Vilson’s keynote, which pointed out that many of the expectations that mathematics teachers have for their students are similar. We ask our students to solve complicated, real world problems that don’t have one single clear answer. Why can’t we do the same when tackling difficult issues?

There’s some good conversations still happening on Twitter now (look for #TMC16 and #1TMCthing). And, like all conferences, even if you weren’t there, you can still catch videos of quite a few of the keynotes and My Favorites presentations where teachers share their favorite aspect of their classroom (Go to #3 on I Speak Math‘s blog). There’s also a lot of good stuff on the Twitter Math Camp wiki.
