computational thinking

1. decomposition

   • definition
     • breaking down a problem into smaller and more manageable problems.
   • example
     • find tallest yr8 class
       • find average height of each class
         • ask students for their height and form
         • calculate averages for each class
           • group forms together
           • add heights together and divide by number of heights
       • select maximum of average heights

2. abstraction

   • definition
     • removing unnecessary details from a problem to create a simpler problem
   • example
     • London, underground map,diagrams,models
   • skill
     • identifying what aspects of a problem are necessary for the solution

3. pattern recognition

   • definition
     • identifying repeating elements to simplify a solution
   • skill
     • to be able to spot repetition and follow instructions with loops
   • example
     • repeat 3 times
       • move forward(2)
         • turn left
