Here is s fully tested and developed book club lesson plan.
It consists of 5-6 days, depending on how fast your group moves. I like to teach this as a summer camp over one week with 8-10 kids, but I have taught this to up to 12 successfully. I run it in the mornings during the summers as a "camp" for 90 minutes.
The best experience I had with this was holding the camp at a city park under the trees. It was a great break from the classroom and kids LOVED it.
I charge $60/per kid + book fees. It is a good bargain for parents compared to the cost of other camps.
This has also been used as an after school program.
Included are detailed lessons for 6 sessions and a flyer that you can customize for advertising. If you want a Microsoft word doc of the flyer, just let me know, I am happy to email.
