Why this why now
Having already encountered logic gates when studying computer systems, pupils are now ready to deepen their understanding of how Boolean logic underpins the operation of modern processors. This unit helps them see how simple logical operations can be combined to solve problems, linking abstract logic to practical computing. Learning Boolean logic develops pupils’ ability to think critically, structure arguments, and apply systematic reasoning, which is valuable in everyday decision-making.
Prior knowledge requirements
- Pupils recognise the Boolean operators AND, OR, NOT and the associated logic gate symbols.
- Pupils can read a trace table for a logic gate.
- Pupils will have used Boolean operators as part of conditions in text-based programming.
- Pupils understand that a binary bit has two states, 1 and 0, and this can represent true and false.

Boolean logic
In this unit pupils will discover that Boolean logic is a way of describing circuits inside a computer. They will recognise logic gates as the building blocks of processors. They will be able to construct logic diagrams, truth tables and simplify Boolean expressions.
