Need help on using Khan to help me teach a small group

I am getting ready to teach a small group of home-educated kids Geometry.   We'll only meet face-to-face for one session per week.  I plan to use Khan heavily to supplement our classtime.

I have lots of experience teaching Math in a classroom, but that was years ago before Khan came on the scene.   I am very unfamiliar with using Khan as a teacher.  I'd like to jumpstart my learning curve on using this tool by talking with  an experienced Math educator who is very familiar with Khan.

I'd pay $15 for a 30 minute Zoom or Skype meeting--is there anyone interested?
