More Problem-Solving Strategies: Look for a Pattern
- January 24, 2014
- No Comments
One of the problem-solving strategies that is often used in math is to look for a pattern. Often when exploring problems, the student can notice a relationship between numbers. This relationship can help to solve the problem by shortening the number of steps it takes to get to a solution.
Step 1: Make a Table
The first step to look for a pattern is to make a table showing the relationships that are there. For example, suppose the problem were to find the next three numbers in the series 2, 4, 6, 8. They are related in a simple way, such that 2 +2 is 4 +2 is 6 +2 is 8. In order to extend the pattern, 8 +2 is 10, +2 is 12 +2 is 14. Therefore, the next three numbers are 10, 12, and 14.
Step 2: Find the Relationship Between Numbers
In the previous example, the relationship was very simple, as the pattern was the set of the first 7 even numbers. Each number in the series was separated by the same distance. Suppose the relationship weren’t quite as simple. This time, the numbers in the sequence are 1, 5, 14, 30, and 55. What are the next 3 numbers in the series? 1 +4 is 5 +9 is 14 +16 is 30 +25 is 55. The numbers aren’t even the same distance from one another.
Step 3: Make a Prediction
What do these numbers have in common? After finding a pattern, it’s possible to predict what the next numbers will be. Those differences 1, 4, 9, 16, and 25, have a pattern in themselves. They are the first 5 squared numbers, as 1 2 is 1, 2 2 is 4, 3 2 is 9, 4 2 is 16, and 5 2 is 25. So the next difference might be 6 2 or 36, and 55 + 36 = 91. The next squared number will be 7 2 , or 49, and 91 +49 = 140. The next squared number will be 8 2 or 64, and 140 + 64 = 204.
Step 4: Check the Answer
The sequence with the next three numbers is 1, 5, 14, 30, 55, 91, 140, and 204. The pattern fits in every step of the sequence. If the numbers were added carefully, it would be easy to check each one, as 1 + 4 is 5, 5 + 9 is 14, 14 + 16 is 30, 30 + 25 is 55, 55 + 36 is 91, 91 + 49 is 140, and 140 + 64 is 204. The next squared number would be 81 (9 2 ), and 204 + 81 is 285.

"What is mathematics? Where can it be found? What is it for? What is it about? How is it done? Who uses it? These are just some of the essential questions that Mathematics in the Modern World aims to answer. The book covers the mandated topics and some of the elective ones which are all organized in a logical fashion. In particular, topics include the nature of mathematics, mathematical language and symbols, problem solving and reasoning, statistical tools, graphs, apportionment and voting, patterns and symmetries, coding, linear programming, and mathematical system. Written in a lucid manner, the book will surely enable students to understand not only the concepts presented but more importantly their application to everyday lives. Finally, it offers a wide array of exercises designed to reinforce lessons, introduce topics, and recognize and celebrate the place of mathematics in the modern world."--Back cover.

However, it is important to note that Polya's stages are flexible and not to be taken literally in linear order. To Polya, problem solving was a major theme of doing mathematics and "teaching students to think" was of primary importance. "How to think" is a theme that underlies much of genuine inquiry and problem solving in mathematics.
