Computional thinking

1. decomposion

   • Decomposition is the act of taking a large problem, and breaking it down into smaller, more manageable problems.
   • we decompose problems because it make it easer to solve
   • an example would be if you had a grpoup of people and you wanted to find the averge you would
     • Get all year 8 together
       • Ask them what their height is Collect the data and put it on the data spread sheet
         • Calculate the mean average

2. abstraction

   • Abstraction is the action of removing unnecessary details from a problem to simplify.
   • Abstraction allows us to create a general idea of what the problem is and how to solve it by gathering general characteristics we need and the filtering out of the details and characteristics that we do not need

3. pattern rocognition

   • Pattern recognition is the process of identifying repeated elements to avoid solving the same problem multiple times.

4. algorithms

   • flow charts
     • Terminator=start and end of flow chart= oval
     • Process=something that happens= rectangle
     • Decision=a question that can be yes or no= diamond
   • structure English
     • A structured English algorithm uses short, structured sentences to express the instructions
   • A algorithm is a set of step by step instruction for solving a problem
