If you do not have your own document camera, here is a way that was shared by Kristina Holzweiss - thank you Kristina!
Basically, you will need the following:
- Headband to stretch over the top of your screen
- A mirror of some sort (I used my wife's old compact mirror)
Once the headband (or some sort of stretchy material) is set and the camera is placed over the camera, open Flipgrid, go into the Shorts section and start your video.
I recommend mirroring your video (under options) and then place your whiteboard over top of your keyboard and you have the ability to explain on the whiteboard for your students.
Embedded below is a 1 minute and 52 second YouTube tutorial I created.
