Allow practices to be printable

I wanted to say THANK YOU so much for all this, because this was so helpful during OLSD, or Online Learning while Social Distancing. I love, love, LOVE it! So helpful!

 Now I have a few suggestions. There should be some parts where you can do printable sheets and stuff because so much screen time is bad for your eyes, and if we need help explaining stuff, there can be a printable answers sheet to for parents. 

Also, I believe that there should be a little parental lock or moderation for friending other users because this could lead to scams and possibly cyber bullying. Honestly I have no idea if you can do this or above yet because I just got the app, so...

THANKS SO MUCH KAHN ACADEMY!
