With the left hand/right hand rule I am always trying to keep all the written information on one side (left hand) but sometimes there is just too much information and I can't contain it to one small side of the book. In cases like this I adapt (see pictures above).
Picture 1 and 2 - I used Microsoft Publisher "catalog" template to create a mini booklet. I deleted all of the publisher information that pops up automatically with the template and replaced it with my own. I gave it a title page and wrote all my information on the inside and glued the back cover to the book. This gave me a lot more space to add information.
Pictures 3 and 4 - I just used the standard Word document (see my post on formatting word documents for composition notebooks) and folded it in half. I had students design a title for it and then we glued the back side to the book.
Picture 5 - I just typed in Word without formatting for the notebook and folded it in half and glued it in the book.
