# Testing… 1, 2, 3… testing. This is a test. This is only a test.

Nothing like your back going out to make you feel old. Happens to me every few years, and comes out of the blue. Last time it was when I was brushing my teeth. This time it was tying my shoes. Anyway, after a hospital visit I was told to take a couple of days … Continue Reading ››

# When Factoring Gets Personal

As an author of Sketchpad activities, I like to think that I can pose good problems for students to solve. But as I visit elementary classrooms and watch students use Sketchpad, I realize that a large part of the enjoyment they derive from using our software comes from creating their own problems and sharing them … Continue Reading ››

# You Had Me at Click – TCEA 2012

It's our first time at the TCEA (Texas Computer Education Association) conference here in Austin, TX. Elizabeth DeCarli, Andres Marti, and I have been really impressed with the teachers who have stopped by the booth to play with Sketchpad, TinkerPlots, and Fathom. Andres pointed out that we have had a lot of conversations with middle school teachers … Continue Reading ››

# Touching the Math

Sketchpad has always been great for learning by doing. You can create a triangle and then manipulate the angles with your mouse and observe the results. There is something really primal, though, about using an iPad or a Smart Board, reaching in and grabbing the geometry with your bare hands. … Continue Reading ››

# What’s up with Key? A Response to Dan Meyer

The other week Dan Meyer sent out this tweet. While we appreciate the compliment (and the resulting increase in traffic), it's the first part of that sentence … Continue Reading ››

# Oh, the Fractions You’ll See!

A quick quiz: How many fractions are there? This may sound like an absurd question, but in the context of elementary mathematics curricula, it makes a lot of sense. Think about it: Children encounter fractions like 1/2, 3/4, and 2/6 all the time, but do they ever see 1/100, 31/90, or 499/500? Unlikely. No brave soul … Continue Reading ››

# Shelfware

I went to a workshop recently that mentioned the concept of "shelfware"--software you buy that ends up on a "shelf," not used. Of course, these days that shelf might be virtual. This got me to thinking about iPad apps I've purchased and then minimally or never used, and why. About a month ago, I bought a … Continue Reading ››

# Graffiti as Street Math?

Last night, Key and our sister company KCP Technologies had an outing to the California Academy of Sciences weekly "NightLife" event--every Thursday night, the Academy opens to adults only with a theme of the evening, as well as opportunity to explore all the … Continue Reading ››

# Resources en Español

At the recent NCTM regional conference in Albuquerque, a local teacher stopped by the booth to ask about new features of Sketchpad 5. He then shared with me his website of video lessons for Spanish-speaking students, LaracosMath.com. Some of these Continue Reading ››

# Math Conference Feedback – NCTM Atlantic City, NJ

I am here at the regional NCTM math conference in Atlantic City, so just wanted to share some things I have noted while talking with teachers at our booth today. Thanks to all of you who stopped by to play with Sketchpad, Fathom, or TinkerPlots on the computers, whiteboard, or even … Continue Reading ››
