Since 1986, my writing has largely been devoted to textbooks and other resource materials for students and teachers grades 6 - 14. Included are

- a High School textbook and other materials on Advanced Quantative Reasoning
- a High School series on Integrated Mathematics,
- writing activities for "We All Use Math Every Day" - the outreach program for the NUMB3RS TV shows coordinated by Texas Instruments. [Texas Instruments and NCTM have been providing weekly activities based on the hit TV series, NUMB3RS. Before each new episode, a short, ready-to-use mathematics activity for teachers and students has been posted on the CBS Web site]
- many contributions to Figure This - a national Media Grant of the National Council of Teachers of Mathematics,
- serving three years on the NCTM [National Council of Teachers of Mathematics] Student Math Notes committee.

Speaking at various meetings is a way of interacting with teachers and/or students. Recent talks include :

- "Teaching Algebra and Geometry Through Problem Solving"
- "Art of Questioning: Twenty Questions [or More]"
- "Teaching Mathematics Through Problem Solving: A Personal Perspective"
- "Conversely Speaking: the Power of Thinking Backward
- "Using Mathematics: From Cryptography to Catching Criminals
