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 came up about whether Sketchpad had a … Continue Reading ››
I heard a great radio interview on NPR this week with Tim Storms, who holds the Guinness Book of Records for the lowest note sung by a human. He sang a few low notes for the interview—so low that my non-bionic ears could barely distinguish a pitch.Continue Reading ››
Like other enthusiasts of mathematics, I’m captivated by the way that mathematical ideas can explain things in the physical world around me, and by the way that I can carry out mathematical thought experiments in my mind and then apply the results to control my external physical environment.
Ken Gordon has written our first in a series of guest blog posts from people working with Key Curriculum products in schools. Ken teaches Precalculus and Calculus in an accelerated program at Sisler High School in Winnipeg, Manitoba, Canada. He has been using The Geometer’s Sketchpad since first seeing it at an NCTM conference in 2004. … Continue Reading ››

"What do you like about working here?" I asked during my interview to work at KCP Tech. I was rather struck by Vishakha's response that she liked being able to help people learn math. She thought … Continue Reading ››
Functions are hard for students.
Students seem to master various families of functions – linear, polynomial, exponential, trigonometric, and so forth. They can graph them, evaluate them, transform them, and answer a variety of questions about them. But ask even our better students a question that’s out of the ordinary and we’re likely to be taken … Continue Reading ››
I just started taking two science classes, Biology and Chemistry, in the evenings. This week I participated in my first chemistry lab since 1988, complete with safety goggles and a Bunsen burner. It was so exciting! In the midst of all this chemistry, the neatest thing for me was helping another student with the math … Continue Reading ››
At a meeting of mathematics supervisors this week there was much discussion about how to meet the needs of struggling learners. I thought of the students I’d worked with over twenty years in the classroom, and of how my kids caused me to rethink my teaching. They asked me a lot of surprising questions.
Take this … Continue Reading ››
Over the weekend, I attended the CMC-North conference at the Asilomar conference grounds. It's my favorite math teacher event of the year.
When I was a teacher, the combination of the beautiful, … Continue Reading ››
