Note to Pupils:

HISTORY OF COMPUTER

Counting is the basis of early computers.

Counting devices are things that help us count and keep track of numbers. These can be everyday items like our fingers or special objects like pebbles, sticks, or shells. They make it easier for us to do math and keep count of things.

In the early days of computing, we used our fingers, toes, pebbles, stones, sticks, cowries, and seeds to count.

These early counting methods led to the development of computers.

The Concept of Early Computing

In the days of early counting devices, computing primarily meant performing mathematical operations manually or with the help of simple tools like pebbles, sticks, and fingers.

Evaluation:

What is the topic of our lesson today?
Name two objects people used for counting in the past.
Explain the importance of counting in computing.
Demonstrate counting using pebbles or stones.

Note to Teachers:
Customize the lesson to suit your teaching style and resources. Ensure pupils understand the historical development of computers from counting methods.
