This is a Gardening Calendar, dummy...

An efficient teacher creates a Gardening Calendar for every course she is going to teach, each academic year.  It contains only the most basic information, but it gives a kind-of-map which shows what is going to get taught in each term. Of course, unless there is a miracle, no-one actually keeps exactly to the schedule they draw up at the beginning of the year, but it has three really big advantages:

1. It helps you to be aware if you get a little bit (or even a lot) behind plan
2. It lets you plan important dates (eg trips, moderator appointments) way in advance
3. It allows you to specify what resources you need - like text books - just once, instead of repeating the same stuff on every scheme of work or lesson plan.
4. It makes you find out important stuff, like how many weeks there are in each term.

I know, that's four.
