| Question | Answer |
| Computational thinking | Thinking about how you can use computers to solve a problem or complete a task, NOT thinking like computers (computers can't think!) or computer programming |
| Three steps that computational thinking involves | 1. Defining and analysing problems 2. Designing structured solutions (an algorithm) 3. Implementing the solution (computer program) |
| Three techniques to solve problem | 1. Algorithmic thinking 2. Decomposition 3. Abstraction |
| Algorithmic thinking | The planning and thought process that goes into designing algorithms, e.g. |
| Algorithm | A set of instructions that can be followed to complete a task |
| Decomposition | Breaking down a complex problem into smaller, more manageable parts, e.g. the problem of revising for an English EoY exam can be broken down into literature and language |
| Abstraction | The process of removing unnecessary detail from a problem, e.g. the metro map is a simplified map, with only the stations and a rough outline of their locations; the buildings and roads are removed |

| What is this called and what is its function? | Input/output, asks for user input or outputs something |
| What is this called and what is its function? | Decision, a yes/no/true/false decision, like an if statement |
