# Heuristics/Problem Solving

 'Heuristics' refers to strategies that we can adopt to solve unfamiliar problems. The following are some heuristics you may need  to use to solve non-routine problems: Guess-and-check  -> Useful for solving simple problems and together with as systematic listings, this strategy helps to narrow down to the correct guess in the shortest time possible. Make a list  -> Commonly used with 'Look for patterns' strategy as it accounts for all possibilities systematically. It organises, presents or generates information in a systematic manner. Look for patterns  -> As it involves active search from a sequence of figures or numbers, information can be expressed/viewed in an organised manner. Draw a model -> Suits pupils who need to see to understand and it translates words or information into pictorial representations. Work backwards -> Useful when the final result has already been given. Simplify the problem -> Separates the problem into sub-problems to be solved individually or in sequence. Before-after concept -> Compare information to find the unknown as it lists information given before and after the action. Model for Problem Solving
