Here are some resources for you to get to know your Chromebook a bit better.
Your new Stylus Chromebook Video (some Chromebooks don't have the stylus but you can still use the tools)
Taking notes and using a scratch pad can be easy on the Chromebook!
Kami App - sign in with Google - open docs to write over them or start with a fresh page
Jamboard.google.com - easy whiteboard app (saves to Drive)
The 1:1 Agreement/Contract - make sure you know what is expected of you and what you are being held to. Most of it is common sense but you should be aware.
You are responsible for this Chromebook until you leave high school so please take care of it.
