Home made Abacus
Materials : Wooden batten (lipping pattil), Pencils, Beads
Slipper can also be used instead of wooden batten
Using Slipper/Wooden batten :
- A simple abacus can be made from a used rubber slipper/wooden batten.
- Make three equidistant circular holes in a slipper with a shoemaker’s punch, Or drill in wooden batten. They should be just big enough so that a pencil can fit tightly in them.
- Stand three pencils in the slipper. Cut the pencils so that only nine beads can be fitted in one pencil.
- The pencils represent place value – the right one “units” the middle one “tens” and the left one “hundreds”.
