Virginia Glatzer asked me to post the replies to my list serv posting on this topic. Here they are:
I have a calculus teacher who has some good ideas.

I also work with Junior High, and right now a teacher is doing a Micorsoft Publisher project with her math students during PSSA week/s. They created a flyer, developed a company name and decided what products to sell. They listed original price, then gave a % discount, figured out the new total and added 6% sales tax to their item. I like how the teacher allowed them to collaborate together and complete this project with a partner. The teacher created a nice outline for the project that I could get for you if you're interested.

We use Geo Sketchpad, Fathom, and Carnegie Learning with our CFF laptops. Fathom works well with statistics classes and we have used it with a trig class. It also is useful for science. We use Carnegie with our Geometry classes and some Algebra classes. Carnegie is more of a whole curriculum choice, though.

I have a teacher here that is using Geogebra with her students. What she did was created a list of equations that that students input into the program and then see the graph. After to this a couple of problems she has a section in the assignment where they are supposed to predict based on the information they got from the previous exercise. If there prediction is right they can move on if the prediction is wrong, they need to explain what happened. It worked pretty well, the students really seemed to get it. Something else is Moodle. There is a chat function on Moodle which makes the room secure to users. Some teachers are using this to discuss information about a topic and having students ask questions by either raising their hands or typing it into Moodle chat. I don't know how that one went because that was the idea...

Look at dgoshorn.com/video for a streaming video of a math lesson that I taped where the teachers uses a graphic app called Geometer's SketchPad along with photos from the internet to talk about triangle congruence. It's about 45 minutes long, so fast forward to the good parts - there's even a part where I zoom in on a kid's screen to show the graphics.

There are all kinds of math applets online that I used with my students in the math classroom. Try searching under “mathlets” I also have many applets bookmarked in my delicious account: del.icio.us/kmshurley

Our math teachers use the software that comes with their texts. They also use Geometer's SketchPad. One of them, our Geometry teacher, has even done podcasts where students used self-made clinometers and measured objects in and around the building to then determine their heights through equations.
They documented their work with digital picts and then put the picts in their podcasts and explained the math they did to arrive at their solutions.
They also included pictures of their hand-made clinometers in the podcast.

Using www.skrbl.com, (which is down right now ??) or http://www.scriblink.com you could have the teacher have a problem on the shared whiteboard and then allow a different student do each step of the problem interactively using the shared whiteboard. There are some classroom mgmt issues of how to identify students, b/c you can have an anonymous session.
If you are allowed, you could have the teacher and students create accounts then their shared whiteboard can be private and users would be identified. If anonymous session is in use, the teacher would be assigned as the “Host” and any student as “guest1”, guest2”, etc. If the session is anonymous you could have the students join the session in some order so you would know who guest1 is and guest2, etc.
These tools could be used in any discipline in a similar manner.

It'll take you a while to work through this laundry list of math sites, but I have found these useful. I teach lower level math, so the sites favor Algebra, but there are some sites with Trig & Calculus.
