Design a game that uses variables
Lesson details
Learning outcome
I can design a project that builds on a given example.
Key learning points
- You can choose or create you own artwork for a project.
- You can create an algorithm which describes your project.
- You should be able to explain your design choices.
Keywords
Design - a plan that shows how a program should work
Algorithm - a precise set of ordered steps which can be followed by a human or a computer to do a task
Common misconception
I want to start coding my game right away! Why do I need to draw pictures and write descriptions first?
By designing first, you're planning out exactly what you want your game to do and how it will work before you write any code.
Teacher tip
In this lesson, learners use elements of an existing coding project and consider how they could modify it. In the next lesson, they will create their own project. You will need a clear understanding of the definition of the term "algorithm".
Equipment
Pupils will need access to a device with block-based programming software. Examples in this lesson use Scratch https://oak.link/scratch

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.
