As I indicated in the email, the following "assignment" is completely optional. You can do as little or as much as you'd like (or none at all), but I really think it is worth your time as you begin your high school years. These work best if the parent(s) and student watch/read/discuss them together, at the same time. I've structured these into multiple sessions to try to divide it up (perhaps do one, then wait a day or two, and then do the next), but you are welcome to proceed through it however you'd like. I think you would find this the most valuable if you completed this before school starts on August 18th, but it's great to refer to it at any time.
Session 1: Fixed Versus Growth Mindset (~20 minutes, plus any discussion time you might have)
Session 2: I Want You To Make Mistakes (Really) (~20 minutes, plus discussion time)
Session 3: Failure is not an option; it's a requirement (~20-40 minutes, plus discussion time)
Bonus Session: If you want to learn even more
