Controlling with conditions
Lesson details
Learning outcome
I can write a program which contains a conditional loop.
Key learning points
- Conditions are either True or False.
- A conditional loop repeats a chunk of code until a condition is met.
- Microcontrollers can be programmed to respond to inputs.
Keywords
Condition - a statement that can be either True or False
Conditional loop - a chunk of code that repeatedly runs a section of the program until a condition is met
Common misconception
A condition can have multiple possible answers.
A condition must always be either True or False in a program.
Teacher tip
Model how to connect and use a push button switch with the Crumble controller, as this is key to enabling pupils to use inputs in their programs.
Equipment
Pupils will need access to a microcontroller, crocodile clips, battery packs, Sparkle LEDs and push button switches. Examples in this lesson use Crumble https://oak.link/crumble

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.
