New teacher... where to start??

Hi sruosh,

The Khan for Educators course is a great place for new teachers to start! This mini-course is meant to familiarize new teachers with Khan Academy, including how to use the assignment and reporting features.

The How to Get Started section in our Help Center may also be useful: https://support.khanacademy.org/hc/en-us/sections/4404531137293-How-to-Get-Started

Please let me know if there's anything I can assist you with or any questions I can help answer!
