After 10 years of teaching, I've personally found this to be the most successful weekly overview I've used. You can edit the template to adjust how many sessions you teach per week, and how many breaks you have. I include quite a bit of detail in my planner, but you can remove this to just include more basic information. I've also included two boxes at the top for reminders and jobs to complete, which I've found to be handy to keep me focussed and organised for the week.

I hope you find this resource useful too!
