A post on Fawn Nguyen’s site reminded me that in one of my other lives I was just a middle school **computer** teacher! And then following those few years when I only taught computers, I taught math in a computer lab. Even though it’s pretty much ancient history, I thought it might be fun to share some of the ideas — if you are a math teacher with access to a lab (portable or another room you can use) or if you are a computer lab teacher who wants to support math teachers maybe you can adapt some of these ideas to 2012!

**Tessellation Tutorials**

I developed this idea (namely, this HyperCard tutorial: http://mathforum.org/sum95/suzanne/tess.html ) for my computer elective students. At that time (1995) HyperCard was the only software on the Macs in my lab! Between 1995 and 2000 I added other tutorials for other software programs. I’ve not added anything lately but there’s probably enough there to figure out how to adapt the idea to a paint program that your students have access to on their computers.

CCSSM: developing understanding of transformations (translation, reflection, rotation) in middle school would support what’s expected of students in High School: Geometry

**Traffic Jam Activity**

(includes a link to Mike Morton’s applet – he wrote for me in 1996 and amazingly it still works!)

**Ask Dr. Math “Link” pages**

I used to write web pages with a focused number of Ask Dr. Math threads. I had students work in pairs and take “Cornell Notes”

These are the pages I wrote:

But you could also use some of the
