Computational thinking

Computational thinking

1. Abstraction

   • The act of removing unneccesary detail from a problem
     • This simplifies it
   • Example
     • A London Underground map
     • Diagrams and models
   • It makes it easier to solve a problem

2. Decomposition

   • Breaking down a problem into smaller problems
     • It makes it more manageable
   • You can make a decomposition diagram to show the breakdown

3. Pattern Recognition

   • Identifying repeating elements to simplify a solution
     • Create loops
   • Example
     • You can use things like: Repeat 3 times
       • Then move forward 2 steps then move up 4 steps

4. Algorithms

   • A set of step by step instructions to solve a problem
   • Flow charts can be created for an algorithm
     • Terminator
     • Process
     • Decision
   • Structured english
