Lesson details
Key learning points
- A logic statement is a statement that evaluates to either True or False.
- You can write a logic statement to represent an outcome where the result is dependent on Boolean variables.
- Boolean logic combines multiple logic statements into an expression that is either True or False.
Keywords
Boolean - a data type that can have one of two possible values, 0 (False) or 1 (True)
Logic statement - an expression that is either True or False
Logic expression - a combination of logical operators and variables that is either True or False
Common misconception
Boolean logic statements should be processed in the order they are read (from left to right).
Boolean operators have an order of precedence that affects the which operator applies to which variable. If a different order is required, brackets should be used.

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.
