1. Decomposition

   • Definition- breaking down problems into smaller, more manageable problems.
   • Example- to create a decomposition diagram for a problem.

2. Abstraction

   • Example

3. Pattern Recognition

   • Definition
   • Example-

4. Algorithms

   • Definition
   • Example

5. Decomposition

   • Definition
     • Breaking down a problem into smaller, more manageable problems.
   • Example
     • To create a decomposition diagram for a problem
   • When could we use this
     • We can use decomposition to break a crime down into small clues to find evidence and make it easier to find the criminal

6. Abstraction

   • Definition
     • Removing unnecessary detail from a problem to create a simpler problem
   • Example
     • Identifying what aspects of a problem are necessary for the solution
     • London Underground map, diagrams, models..
   • When could we use this
     • We could use this when looking on a map, trying to find where you may be.

7. Pattern Recognition

   • Definition
     • Identifying repeating elements to simplify a solution
   • Example
     • To be able to spot repetition and follow instructions with loops
     • Repeat 3 times Move forward (2) Turn Left
   • When could we use this
     • We could use pattern recognition whilst baking
     • We could use it when getting given directions

8. Algorithms

   • Definition
     • A set of step-by-step instructions to solve a problem
   • Example
     • follow and create Structured English algorithms and Flow charts.
   • When could we use this
     • We can use Algorithms in an airport to test if the bags are light enough to go onto the airplane, for example it cant be more than 50 pounds, if it is less it gets accepted if it is more it gets rejected.
