Scratch is a project of the Scratch Foundation, in collaboration with the Lifelong Kindergarten Group at the MIT Media Lab. It is available for free at https://scratch.mit.edu.
Unit outcomes
Pupils who are secure will be able to:
- Understand that problems can be solved more easily using computational thinking.
- Recognise decomposition, abstraction, algorithm design and pattern recognition as key computational thinking skills.
- Explain how decomposition and abstraction simplify problem-solving.
- Identify patterns in problems and use them to solve problems.
- Design clear algorithms and justify their choices.
- Create logical sequences of steps to complete a task or project.
- Use computational thinking skills to code, refine and evaluate their work.
