Lesson details
Key learning points
- A variable is used to store a value in a program.
- A variable can be updated with a new value which replaces the initial value it was assigned.
- The value of a variable can be tracked throughout a program.
Keywords
Variable - a named piece of data, stored in a memory location in a computer
Value - the data a variable holds at a particular time
Trace - to track the value a variable holds at any time during a program
Common misconception
The value a variable holds cannot be updated and a computer remembers the previous values of variables.
A variable can be updated during a program. Once the value of a variable is updated in a program, the previous value is overwritten.

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.
