Starting with Sketchpad Activities on Day One in Grades 5-8

In the Dynamic Number project, one of our goals has been to create activities in which students actually experience mathematical objects by creating them, manipulating them, and investigating them. (George Lakoff and Rafael Núñez describe, in Where Mathematics Comes From, how students' abstract mathematical concepts are grounded in … Continue Reading ››

Revisiting a Childhood Addition Code with Sketchpad

As a fourth-grader in 1977, I had a love-hate relationship with my Addison-Wesley 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: Each appeared in a box set aside from the main text and featured a bespectacled … 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 offers a new option for teachers to help students learn about proportional … 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 came up about whether Sketchpad had a … Continue Reading ››

Functions Come Alive in a Precalculus Classroom

He has been using The Geometer’s Sketchpad since first seeing it at an NCTM conference in 2004. … Continue Reading ››

What’s the Appropriate Role for the Teacher when using Computer Games?

I had the privilege this year of participating in the CADRE Fellows Program of NSF's Community for Advancing Discovery Research in Education, and met a number of colleagues in the program whose projects, like our Data Games project, are exploring the classroom benefits of computer-game- or simulation-based-learning. (In this post, I’ll refer to technology-oriented … Continue Reading ››
