Stokes Publishing Company started publishing teacher resource books in 1972. Our founder, William Stokes, developed and patented the unique Overhead Calculator in 1979. This technology supplies teachers the capability, by using any standard overhead projector, to project both the calculator display and the whole calculator keyboard for ease of instruction. In association with Texas Instruments, Casio, Sharp and other producers of educational calculators, we produce a whole spectrum of overhead calculators that perfectly emulate a huge range of non-graphing and graphing.
