Teacher required graph paper for math class and this fit the requirements. Student loved having holes prepunched for easy addition to binders and ability to rearrange as needed. The color of squares is bright enough to easily see without being overwhelming when looking at diagrams/designs. Paper is strong enough to withstand several erasings in same spot for errors/accidents. Paper is heavy enough weight to not tear easily when added to or rearranged in binder. Counters on margins would be helpful for some projects but not always necessary.
