**FOUR PHASES IN SOLVING A PROBLEM,**

From the book: *How To Solve It*, George Polya, 1945

**(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
