Throughout this term Grade 6 have been studying the uses of the Abacus and its origins.  Using their knowledge they created their own abacus instruments.

One example of archaeological evidence of the Roman abacus dates to the 1st century AD. The normal method of calculation in ancient Rome, as in Greece, was by moving counters on a smooth table. Marked lines indicated units, fives, tens etc. as in the Roman numeral system. This system of 'counter casting' continued into the late Roman empire and in medieval Europe, and persisted in limited use into the nineteenth century.
