A wonderful, student centered reference tool for teaching geometry and measurement! Just create the booklet and copy!
To make the booklet, get 6 sheets of copy paper. Take one sheet, fold in half and make tiny cuts in the crease 1 inch from top and bottom. Begin at either cut and cut down the crease to the next cut and when you open the paper, you should have a rectangle-shaped hole in the center. Get the other 5 sheets, fold in half. Cut a litter over an inch from the top of the paper down the crease on each side. Fold the 5 pages in half the long way (do not crease them again) and slide them through the hole in the 1 sheet. Fold the 5 pages up and they will lock with the 1 sheet...a booklet that will stay secure with no staples!
