Teacher has internet access, but students do not.

I am a 6th Grade Math Teacher and would like to use Khan Academy as my primary curriculum for the year. I would like to present the lesson with the Khan video and of course review with the class. I do have internet access at the school via a desktop computer on the teacher’s desk. I can even show the videos/PDF on a smart board. The problem is that the school does not allow the students to have internet access. Therefore I can present the Khan lesson but from then on I would need to print worksheets for classroom practice, homework, and exams.

Can you please tell me the best way to run the classroom for the year using your program with the above parameters/restrictions.
