How much paper do you use?

There has been a positive movement to reduce/recycle/reuse that I have seen taken to heart by the students I work with. However as students progress in math they need to let go of previous ideas held about fitting each homework assignment onto a single sheet of paper. I remember my 10th grade math teacher Mr. Saltzman who wouldn't accept any assignment unless there was a blank line between each problem, no writing in the margin, and two empty lines at the top and bottom of each page. Contrast that image with what I often see: students trying to do a 6 step problem all on one horizontal line, no space between problems and/or small illegible writing. When you go shopping for those notebooks at the beginning of the quarter, semester, or year pick up the 5 subject-perforated-college ruled ones. These hefty notebooks are not to be used for 5 different subjects but rather dedicated just for math. In this way you can stretch out and allow yourself plenty of physical and mental space to complete those assignments. Furthermore, you will have the space to be more organized and can see where you are making errors and correct them. Then at the end of the year if you choose not to save your notebooks you can always RECYCLE them!
