A Classroom Workshop

A growing collection of tools, activities, and experiments shaped by the everyday work of teaching mathematics. Each project began with an idea about how a web-based resource might support my work as a teacher or my students’ work as learners, then took shape through real classroom use. The projects continue to evolve as I use them, learn from them, and reflect on the value they offer in practice.

Advanced Algebra
OpenStax Viewer
User-friendly presentation of OpenStax math textbooks, including detailed navigation, embedded Desmos interactive graphs, and a coordinated practice-panel view.

AP Statistics
Data Visualization Exploration
A final project asking students to engage with generative AI to produce interactive visuals that tell a story from data.
Open →
Which Test?
A quick in-class activity about choosing appropriate inference methods, hypotheses, and significance levels.
Open →
Inference Practice
AI-powered scenario practice using the State–Plan–Do–Conclude framework. Structured feedback at each step—you can't skip to the end.

Mathematics · Middlesex School, Concord MA · since 2012

I teach mathematics at Middlesex School, where I also chair the AI Advisory Council and head the Math and Computer Science departments. My classroom spans the full range of high school math—from introductory courses through AP and post-AP—and my ongoing studies keep me close to both the math itself and the evolving research on how students learn it.

I use this site as a workshop for ideas that emerge from teaching. Some projects help me manage the work more thoughtfully; others help students explore concepts, practice with purpose, or become more independent learners. Increasingly, that work also involves figuring out where technology and AI genuinely support learning—and where they do not.
