Well, no more.
For my conic sections notes sessions in Precalculus, I'm using Desmos-created graphs with all their equational and slider glory.
Here's how I ensure kids have readable, meaningful examples in their INBs:
I've created some modified graphs of the Desmos parabola graphs — one with a vertical axis and one with a horizontal axis.
I take a screen shot of the equation drawer PLUS the graph and paste it into an Omni Graffle document. For those of you playing our home game on the Mac, that's:
- Press Cmd-Shift-4 to enter screen grab mode
- Select the region of the Desmos window that you want to use as your graphic (this pastes it directly onto the Mac OS X clipboard)
- Paste into a blank Omni Graffle document (from omnigroup.com )
- Resize to fit your needs, then
- Select, copy, and paste as many times as you need to create the master for your tiny handout
Here are the files for my photocopy masters:
I recognize this is totally old school, but everything old is new again.
