The use of computers to solve problems.

Development of algorithms to solve problems.

Using abstraction, decomposition and algorithmic thinking.

Representing 'real world' problems in a computer using variables and symbols and removing / hiding unnecessary elements from the problem.

Breaking down a large problem into smaller sub-problems.

• Smaller problems are easier to solve

• They can be solved independently of the other problems

• They can be tested independently then combined to produce the full solution.

There is not always one right answer.

A problem could decomposed in several valid ways.

Identifying the steps involved in solving a problem.

What are the steps involved in the calculation 200 ÷ 12?
