Creating games
Lesson details
Learning outcome
I can create a project that includes repetition.
Key learning points
- A program can be built by implementing a design and algorithm into code.
- The order of blocks inside a loop affects the outcome.
- Testing and debugging are necessary steps when building and refining a program.
Keywords
Algorithm - a sequence of steps that can be followed to do a task
Debug - the process of finding and correcting errors in code
Common misconception
The order of the blocks inside a 'forever' loop doesn't really matter, as long as they are all in there.
The order of the blocks inside a loop can matter, and running them in a different sequence may affect the game.
Teacher tip
If pupils haven�t completed their own game design sheet, use the included Bat Catching Game design sheet. Having a ready-made plan helps pupils focus on practising the coding skill (repetition) rather than increasing pupils' cognitive loads by getting them to do too much within a single lesson.
Equipment
Pupils will need access to a device with block-based programming software. Examples in this lesson use Scratch https://oak.link/scratch
Licence

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.
