Introducing the Dynamic Number Project
Four years ago, my colleague Scott Steketee and I began brainstorming new Sketchpad activities for a National Science Foundation grant called Dynamic Number. Our goal was to use Sketchpad to make ideas from number, operation, early algebra, and algebra come … Continue reading
Revisiting a Childhood Addition Code with Sketchpad
As a fourthgrader in 1977, I had a lovehate relationship with my AddisonWesley textbook. Its contents overflowed with arithmetic problems, but every so often an entertaining brainteaser appeared to break the monotony of drill practice. These puzzles were clearly marked: … Continue reading

Exponential Harmony with Sketchpad
Last week was the fourth session of my spring Advanced Secondary Math Methods class at the University of Pennsylvania. Each year I assign a semester project in which groups of three students use lessonstudy techniques—on a small scale—to create, test, … Continue reading

Beat a Path to the Museum of Math
http://www.youtube.com/watch?v=jK7xPo1YXzY”>video
As a New Yorker, I have no lack of museums to suit my every viewing whim. Matisse? Just head to the Metropolitan. Edvard Munch? The Scream is at the Museum of Modern Art. But where should I go when I’m … Continue reading
Sketchpad––Yes, It Can!
Last week I ended my fall math conference touring schedule. It’s been a funfilled road trip—in the span of two months I’ve been to all three NCTM regionals in Dallas, TX, Hartford, CT, and Chicago, IL, not to mention AMTNYS … Continue reading

Understanding Proportional Relationships with the Proximity Data Game
In the Fall as Middle School and Algebra 1 teachers look for activities to develop students’ understandings of proportional relationships, they may turn to measuring scale diagrams or using springs. One of KCP Technologies’ new online Data Games called Proximity … Continue reading
Edtech Tools are NOT Just for Students
I wanted to share a couple experiences I had in the last two weeks that have reminded me that even adults can benefit from dynamic mathematics software that we typically only associate with students learning math. My experiences relate to … Continue reading
“Figuring It Out” Is Where the Learning Happens
I often get asked the question when doing webinars, workshops, or professional development training, “is there a quick way to do that” with Sketchpad, TinkerPlots or Fathom? For example, last week we had a webinar on functions, and the question … Continue reading
CrossCurricular Teaching of Data and Probability
We here at Key really love our TinkerPlots software. And we’re always talking about the power of using it crosscurricularly—using data to enhance understanding of, say, science or social science topics, as well as using these contexts to motivate the … Continue reading
