You can make your own planner if you have office management software. We did this using a weekly calendar. I printed August through December in advance and bound the whole document with a spiral binding. If you do not have a binder, a printing shop will do this for a small price. This makes a portable planner that is easily adapted.
Binders can hold all the necessary supplies.
This is much like an attach case for a student. A binder should be large and should have a 3-ring holder. Another great feature is the pencil container. We found a binder with two sections so it could contain index cards and a planner. Search for a good one.
