Make or purchase an apron with pockets. You can use a carpenter’s apron or craft aprons. Carson-Dellosa also sells a 3-pocket teacher apron made of durable material. Keep those supplies that you use frequently during the day in your apron. In mine I keep: a red, blue, black, and green pen; a dry erase marker; an overhead marker; a piece of chalk; blue strips; post-it notes; and a ring of cards with students names on them (Ring of Student Names).
