Hi Slate,

Our mastery challenges are designed to prevent users from doing too much at a time, which helps ensure retention of the skills they have learned. Otherwise, Khan Academy is meant to be used at your own pace.

Let me know if you have any further questions!

So our class does 20 minutes at least  if you want to you can do more of khan academy!

We are also new to Homeshooling & Khan Academy.  Right now, my daughter is doing 7th grade Language Arts.  How do we know how much time she should be spending per day on this subject?  Right now she has only been concentrating on Language Arts.  Definitely need to also start Math!! 

HELP!!! 

In youtube, if you have watched for an hour, there is a reminder to take a break. Would be good to have something of that nature on this site too. Can the site provide Mediation and yoga after an hour or so, as an option?

We ask our student to attain 200 "up arrows" in a day. We count them by going to progress for World of Math and counting them. A bit tedious to count them up, but that's what we do. Our student spends 1- 3 hours attaining this depending on if focus is placed on fundamentals already surpassed, or facing new material and learning new methods.
