Transform your math instruction.

We know two things: Teaching math is hard work.  And good mathematics teaching makes an enormous difference.  

So how do we grow our mathematics practice? the number lab offers a progressive professional development model that opens teachers up to possibilities and invites them to adopt and refine new practices in a lab setting.

Attend our Educators' Collaboratory.

Our Educators' Collaboratory is a summer workshop held in Austin, Texas at The AT&T Center at The University of Texas and involves teachers in an intensive 4-day experience that provides an introduction to the mathematical big ideas that promote Number Reasoning. The Advanced Collaboratory (for past participants) deepens teachers' understandings of the complex practices in a number lab classroom. 

Sign up for a Field Study Day.

Field Study Days (fall, winter, and spring) at our micro-school support teachers as they work to shift to new practices that scaffold deeper conceptual development. Field Study Days offer a unique opportunity to take part in a classroom experience, study student thinking, and reflect with colleagues.

Register for a One-Day Workshop.

One-Day Workshops during the school year are a great way to keep learning more about the number lab practices, content, and routines. We typically offer several of these throughout the year on Saturday morning.


Contact us to create a customized workshop @your school.

We travel to internationally and within the US to innovative schools interested in customized two or three day workshops. Contact us at for more information.

I knew I needed to encourage my students to explain and think about their thinking, but because of this lab-based professional development, now I know HOW.
My new understanding from our 3-day p.d. session is that we must make our math transferable: that is key!
“I learned so much! I loved the language and I now understand how to elicit understanding of a number as a unit, as this is an idea we can help kids grow to every other type of number.”
This was the best professional development I have ever attended!
