keep her as busy as you can.

Allowing the child to get water or go to the bathroom may help so that she can move around a bit. Also if you had a random time each day that everyone in your class room stood up and stretched or something for just a minute (like they do for long tests) might be beneficial. Hope this helps!

Get her a standing desk Direct questions toward her to keep her “on her toes”.

I'm on the same page as some others. If possible keep the student moving and active physically & mentally. Sitting / any form of relaxing (for myself anyway) has always been extremely difficult for me to do without falling asleep, with or without meds doesn't matter. Once I get out of bed I try to stay on my feet so long as I need to be awake, productive, etc. Hope the student gets the help they need soon. God bless you for caring about your students!!

Have her do something active. Instead of just sitting and listening, have her write or play with a stim toy or read out loud I have no idea what the subject is but if she’s just sitting still and listening then give her something to do. Or let her sleep? If she’s that deprived of sleep she’s not going to learn anything anyway, so she could still make use of the time by getting some much needed sleep in. I have no idea how feasible any of that is within a classroom.
