FOUR PHASES IN SOLVING A PROBLEM,
From the book: How To Solve It, George Polya, 1945

how to

(1)    Understand the problem

  • What are the data?
  • What is the unknown?
  • Is there enough information to enable you to find a solution?
  • Can you restate the problem in your own words? 

(2)    Devise a plan.

  • Do you know a related problem?
  • Look for a pattern
  • Use a model
  • Work backwards
  • Use a formula
  • Use direct reasoning

(3)    Try It

  • Carrying out your plan of the solution.
  • Can you prove that it is correct? 

(4)    Look Back

  • Examine the solution obtained.
  • Does your answer make sense?
  • Is it reasonable?
  • Can you check the result?
  • If you missed something check your plan and try the problem again.

Sequence.  Is a set of numbers in which the numbers have a prescribed order.
                       10, 15, 20, 25, …
                       10, 20, 40, 80, …

Pattern.  A design (geometric) or sequence (numeric or algebraic) that is predictable because some aspect of it repeats
