MfA Muller Award for Professional Influence in Education

Published: Tuesday, October 18, 2022

I am the 2022 recipient of the Math for America Muller Award for Professional Influence in Education.  This award is given to two New York City public school teachers who, during their tenure as MƒA Master Teachers, have influenced the teaching profession in exceptional ways.

“ am deeply honored to receive the MƒA Muller Award. This award reflects not just my efforts but the work of a community that respects the professional expertise of educators so that we can work together to improve math education. Over the years, my colleagues have helped me realize that math should be taught as a language that all students can access. When we teach students how to read, write, and speak math, they strengthen their mathematical confidence and can use it to improve the world.

Here is the Math for America press release about the award:

Algebra I Calendar of Lessons

Published: Thursday, September 1, 2022

This year, I'll be teaching Algebra I for the first time since 2016. I've worked out a calendar of lessons based on the latest book that Larisa Bukalov and I wrote, Practical Algebra: A Self-Teaching Guide (3rd edition) (Jossey-Bass, 2020). I'll be teaching mostly in the order in which we presented them in our book.

My calendar includes days for tests, test review, and occasional catch-up days as well as other assessments and school events. The calendar is available in Google Calendar format at
