'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.
