1. decomposition

   • breaking a problem down into smaller more manageable parts
     • we use this when the problem is to big to solve at once so we break down and solve smaller problems to get the answer to the main question

2. abstraction

   • removing unnecessary detail from a problem to create a simpler problem
   • this is useful because we can identify what parts of the problem are helpful for the solution
   • examples of this would be the London underground map, diagrams or models

3. pattern recognition

   • identifying repeating patterns to simplify the solution
   • be able to spot repetition and follow instructions for a loop

4. algorithms

   • a set of step by step instructions to solve a problem
