Who is this website for?

This website is for teachers and has everything needed to lead a classroom exercise in which each child builds their own simple math machine.

For each machine you will find:

  • A list of parts needed to assemble the machine (including where to buy them and how much they cost)
  • Illustrated, step-by-step assembly instructions
  • A list of problems – each machine is a self-contained lesson

Simple Math Machines are the creations of Richard Freedman, an amateur inventor, lover of math and how to teach it.
