An Introduction to the Abacus (Extra 9)

What is an Abacus and why would you use one? In this session, led by James Bowden, participants learnt about the various features of the Abacus and why it is ideal for use as a blind person.

The session covered:

  • Physical description and orientation
  • The beads and their meaning
  • Setting numbers
  • Basic addition

If you have an Abacus, you might find it helpful to have it with you so that you can follow along.
