Abstract
Simply put, anything that can be counted may be
considered to be counters. So, pebbles, chalk pieces,
bottle caps, seeds, buttons – all these are familiar
objects which can be utilised as counters. Square counters
can be made easily from (corrugated) cardboard boxes by
drawing a square grid with squares of side at least 2cm and
then cutting it up. Cutters (with steel scales) work much
faster for corrugated cardboard than scissors. Making round
counters from cardboard is more tedious but not impossible
(with difficulty decreasing as size increases). Carrom coins,
bottle caps (ideally of the same size), tooth paste caps are
great as round counters. It is advisable to paint the counters
in bright colours especially for younger children.
