30 minutes session
These sessions are primary for younger children. Usually children under the age of 6 or kindergartner grade level do not have the attention span for much more than 30 minutes. I recommend two sessions a week.

45-1 hour session
By 1st grade, children can usually sit and learn for 45 minutes. I try and keep these lessons entertaining so the child stays engaged and keep interest. I always end the lesson with a fun learning game.
One hour sessions are encourage by 4th grade and older. These lessons are little more involved with more reading and writing.
I recommend two sessions a week for both.
