Why not block all ports except 80 and 443 for that host during certain
times during the day?

Avoid this approach. OK, this is a Linux list and the reasons for
avoiding this approach are probably off topic, but in essence you are
putting yourself in a position of controlling someone who is becoming an
adult and who needs to learn to control himself. By constraining what is
possible, you are teaching that anything which is possible is
permissible. That's a bad lesson, and you should be prepared to
sacrifice all the schoolwork in the world to avoid teaching it.

It's a familiar question, and you are a good deal more open about it
than many
- I have several times seen it, without a child being mentioned, and
someone replies and mentions 'your child' - at which other posters say
'what child' - and then it turns out to be a child who is being
controlled, sometimes a 17 year old. And then the thread goes sour, when
someone says 'perhaps you should not try to exercise control in this
way' and the original poster says 'who the hell are you to tell me how
to bring up my child?'

At 13, you might think it is appropriate to do control by technical
means, but then you will need an exit strategy over the next few years
during which you will be working through all the things you need to work
through now, only a few years late, with a more resentful son. Or you
could let him leave home, go to college at 19, never having exited from
this control at home, and he will not have learned self discipline, with
predictably bad consequences.
