PDN  Complete your note card as shown:

Due Friday 9/11  Parent and student signature paper You and your parent must agree to the terms in the syllabus  By the numbers: Pick 8 numbers that are significant to you Color your wheel Create an equation that completes your circle (use all numbers on your paper, and check at least 10 times, or until your equation is correct) For a bonus: have a correct equation, and/or make it creative, unique, or pretty

Four-Step Problem Solving PDN  *Write the ENTIRE question down in your notebook before you begin

EXPLORE: UNDERSTANDING THE PROBLEM  Can you state the problem in your own words?  What are you trying to find or do?  What are the unknowns?  What information do you obtain from the problem?  What information, if any, is missing or not needed?

PLAN:  The following list of strategies, although not exhaustive, is very useful.  Look for a pattern.  Examine related problems, and determine if the same technique can be applied.  Examine a simpler or special case of the problem to gain insight into the solution of the original problem.  Make a table.  Make a diagram.  Write an equation.  Use guess and check.  Work backward.

Solve:

Examine: LOOKING BACK  Check the results in the original problem. (In some cases this will require a proof.)  Interpret the solution in terms of the original problem. Does your answer make sense? Is it reasonable?
