There are four stages to computational thinking (smart problem solving).

Decomposition is when you break a problem down into smaller tasks so that it is easier to solve.

Pattern Recognition is the process of identifying similar patterns within a problem.

Abstraction is when you ignore unnecessary information and focus only on the important facts.

Algorithms are the final stage as step-by-step rules are created to solve the problem. An algorithm is usually written as psuedo-code or presented as a flowchart.
