Introduction/Definitions: Teacher introduces the topic early counting device to the students as follows:
What are Early Counting Devices?
Early Counting devices were the means of counting and calculation used in the early ages. They include the use of fingers, feet, toes, pebbles, grains, sticks, cowries, etc. for different counting needs. The major problem with these devices is that they cannot be used for counting large numbers efficiently, they also occupy large space, and they waste time. The computer was developed as a result of the efforts of scientists who wanted to reduce the problems encountered while counting and calculating using early counting devices.
Early Counting Devices
- Fingers and toes: the ten fingers and ten toes were used for giving account of days, trading and children. The early people also used feet to measure land.
- Pebbles and grains: pebbles are small round stones that were used for counting. Grains from the farm such as corn, beans and rice were also used for counting.
