One source of free and inexpensive materials to support the study of mathematics can be found at the local hardware store or lumberyard. Many common objects can provide numerous opportunities for students to develop mathematical concepts and skills (Olson and Olson 1998). A pound of nails, washers, or other small inexpensive hardware items can be purchased for a reasonable cost and used as markers, counting devices, or items to measure.
