I needed extra on hand for when my students need addittional visual aid, we don't spend time looking for it nor spend time drawing on blank paper as I keep this in a tray within reach for all to use. I found this option more cost effective than single 20-30 sheet packages.

I just purchased the 1" graphing paper for creating graphs. Those squares are larger and provide more space for coloring and labeling. This paper, however, is more suited for creating arrays for multiplication for my beginners. They can figure out problems with addends up to 12, and also work on area and perimeter. Also, the double-sided format allows for practice (draft) and final copies.
