Schedule 30-60 mins to go over the pre-read material with the board. ideally you would spend that time discussing the pre-read and not presenting it as you should assume and expect everyone will have read it.
I would then spend the rest of the meeting on 1-2 key strategic topics that you are spending a lot of your time thinking about. use this time to get the board’s feedback and input on these topics.
This includes a great outline for running a board meeting (for most any organization).
