## Learning objective

- To use simple operations to calculate bit patterns

## National curriculum

Pupils should be taught to:

- Understand computer networks including the internet; how they can provide multiple services, such as the world-wide web; and the opportunities they offer for communication and collaboration

## Differentiation

**Pupils needing extra support: **Instead of adding the two numbers, they could try to work out the value of the numbers and calculate this way:

E.g. 111 + 101 = ?

111 = 7

101 = 5

So, 7 + 5 = 12

And 12 in binary would be 1100

**Pupils working at greater depth: **Once they have managed to successfully add two 3-bit numbers, they should then extend to these activities:

- Two 6-bit binary numbers.
- Two 8-bit binary numbers.
- Three 8-bit binary numbers.
