Most mathematics teachers agree that the incorporation of mathematics history into their instructional process would enrich the lessons. The one most common objection to this innovation is the expenditure of teaching time. Compatible but nonintrusive ways must be found to overcome this objection. One such method, which has proved successful, is the use of historical images in the classroom: both during the instructional process and as passive reminders of the human involvement with mathematics. This presentation introduces the concept, supplies illustrative examples and renders advice on the securing of appropriate images. In particular, the historical archive, « Mathematical Treasures » maintained by the Mathematical
Association of America in its e-journal Convergence is recommended.
