  2. Problem Solving in Chemistry 1.4 • Shape-sorter toys fascinate young children. Typically, the children try placing a shape in different holes until they find the right one. The trial-and-error approach is one method of problem solving, but it is usually not the best one.

  3. 1.4 Skills Used in Solving Problems • Skills Used in Solving Problems • What is a general approach to solving a problem?

  4. 1.4 Skills Used in Solving Problems • Effective problem solving always involves developing a plan and then implementing that plan.

  5. 1.4 Skills Used in Solving Problems Shopping involves problem solving skills.

  6. 1.4 Solving Numeric Problems • Solving Numeric Problems • What are the three steps for solving numeric problems?

  7. 1.4 Solving Numeric Problems • The steps for solving a numeric word problem are analyze, calculate, and evaluate.

  8. 1.4 Solving Numeric Problems • Analyze • To solve a word problem, you must first determine where you are starting from (identify what is known) and where you are going (identify the unknown). • After you identify the known and the unknown, you need to make a plan for getting from the known to the unknown.

  9. 1.4 Solving Numeric Problems • Calculate • If you make an effective plan, doing the calculations is usually the easiest part of the process. • Evaluate • Check that your answer is reasonable and makes sense. Check that it has the correct unit and the correct number of significant figures.
