Problem Solving

Understanding the Problem-reread the statement of the problem, draw a sketch or diagram, restate the problem in your own words, make a reasonable guess at the solution. Devising a Plan-come up with a plan on how you are going to solve your problem. Carrying Out the Plan-write your thoughts down. Looking back-verify or check your results by referring to the original problem.  

Introduction to Problem Solving

draw sketches and diagrams.

trial-and-error procedures.

list some or all of the possibilities

use a model to aid in visualizing the problem.

work backward.

Patterns and Problem Solving

Compare and Contrast: compare to find features that remain constant and contrast to find those that are changing. Inductive Reasoning: the process of forming conclusions on the basis of patterns, observations, examples, or experiments. Counterexample: an example that shows a statement to be false.  

Compare and Contrast

Number patterns, geometric patterns, word patterns, and letter patterns.  

Fibonacci numbers

  After the first two numbers of this sequence, which are 1 and 1, each successive number can be obtained by adding the two previous numbers.

Pascal's Triangle-triangular pattern of numbers.

Arithmetic Sequence

Each new number is obtained from the previous number in the sequence by adding a selected number throughout.

Geometric Sequence

Each new number is obtained by multiplying the previous number by a selected number.

Triangular Numbers

Called triangular because of the arrangement of dots that is associated with each number.

Problem Solving with Algebra

Introduce variables with geometric shapes. Use a balance scale for introducing equations in the elementary school. Find all the replacements for the variable that make the equation true.
