There are many different strategies that good problem solvers use to solve a problem. Before using a strategy, you must remember a few things. First, take your time. Few good problem solvers solve problems fast. Second, don't give up. You will never solve a problem if you don't try. Last, be flexible. If a first you don't succeed, try another way. And if the second way doesn't work, try a third way. There are a few steps to solving a problem that you should follow. First, read the problem very carefully. Try to understand every word and make sure you know what the problem is asking. If you don't know the meaning of a word, look it up in a dictionary. Second, sort out information that is not needed. Third, devise a plan. Even guesses have to be planned out. Arrange information in tables, draw pictures, and compare the information to another problem you know of. Fourth, carry out the plan. Attempt to solve it and work with care. If the attempt doesn't work then go back and read the problem again. Last, check your work carefully. Don't check by repeating the problem, estimate or find another way to try and to solve the problem. You can understand what the problem means yet still not be able to solve it immediately. One good way to help you solve the problem is to draw a picture. One example of this strategy is suppose you received a problem asking you how many diagonals a heptagon has. The plan is very obvious. Draw a heptagon and then draw its diagonals. Another strategy is trial and error. Trial and error is a problem solving strategy that everybody uses at one time or another. In trial and error, you try an answer. If the answer is an error, you try something else. You keep trying until you get the correct answer.This is a good strategy to use if the problem only has a few possible answers. Another good problem solving strategy is to make a table. Some times it helps a lot to make one. A table is just an arrangement of rows with columns. Making a table is just one way of organizing information that you know. Below is an example of a table: Number if minutes talked Cost of phone call 1 .25 2 .43 3 .61 4 .79 5 .97 Another problem solving strategies is to use a special case. A special case is an instance of a pattern used for some definite purpose. Special cases help to test weather a property or generalization is true. The only thing wrong with this strategy is that even if several special cases of a pattern are true, the pattern may not always be true. A strategy called try simpler numbers can be used to devise a plan, to solve problems, and to check work. For this reason, it is a powerful strategy. There certainly are many different problem solving strategies a problem solver can use to solve the problem. 1. Mandy is saving to buy a present for her parents' anniversary. She has $10.00 and she adds $5.00 a week. a. How much will she save in 12 weeks. b. How much will she save in w weeks. Answer: a. 70 b. $10.00 + (w*$5.00) 2. Nine teams are to play each other in a tournament. How many games are needed. Answer: 36 To solve this problem I made a table 12 23 34 45 56 67 78 89 13 24 35 46 57 68 79 14 25 36 47 58 69 15 26 37 48 59 16 27 38 49 17 28 39 18 29 19 3. Bill is older than Becky.
