Lesson details
Key learning points
- Boolean logic is a form of algebra where all logical relations can be expressed as a combination of AND, OR and NOT.
- A logic gate is a fundamental component of a digital circuit.
- Each logic gate has a symbol, which is used in circuit diagrams.
- Each logic gate has a unique truth table that shows how the output changes with different inputs.
Keywords
Boolean - an expression that evaluates to either True or False
Logic gate - an electronic component that carries out a logical operation
Truth table - a table showing the outputs for all possible combinations of inputs to a logic gate
Common misconception
All logic gates have two inputs and one output.
The number of inputs depends on the logic gate. The NOT gate is different in that it only has one input.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
