Timeline

Problem-solving techniques like algorithms and flowcharts help solve problems step by step.
An algorithm is a list of clear instructions to solve a problem. Good algorithms are precise, unique,
finite, and effective.
Computational thinking involves breaking problems into smaller parts (decomposition), focusing on
key details (abstraction), recognising patterns, and designing step-by-step solutions (algorithms).
A flowchart is a diagram that shows an algorithm using symbols like ovals (Start/End), rectangles
(Process), diamonds (Decision), and arrows (Flow).
Rules for flowcharts keep them neat, use correct symbols, and ensure a logical flow from start to end.
