"Do you know of any program (free) that lets us look at and manipulate 3d shapes."

Estimating Age

Here's the idea: take any older concept, say the ones on the left side of each slide, and assume classroom proficiency. Then throw a problem at your class that looks like it's assessing the old concept, but which is actually demonstrating the need for the new concepts on the right.



What can you do with this?



Geogebra is a powerful (free!) tool for playing with Algebra and Geometry. Go ahead and download it.

If we built a passenger airplane that could fly nonstop around the world, a) how long would that flight take? and b) how much would it cost?

Let's look at some patterns in airline flight data to figure it out.

  1. Go to United Airlines' website.
  2. Select ten non-stop, one-way flights from Dulles (IAD) to ten different destinations.
  3. Make a chart of:
