Master problem-solving: four steps to become better problem solving and decision making for

Your son or daughter's science homework word problems. How do you help your children become successful word problem solvers? A process that can be applied to a variety of problems by developing your child's help. Recognize that word effectively to meet the problems requires a series of logical steps. The first strategy is to understand the contents of the language of the problem. The second recognizes that science is an application of algebra word problem. Third, problems associated values ​​are described. Fourth, the appropriate algebraic equation to determine the problem. Finally, the whole process of problem-solving document. 1. Successfully complete science word problems requires good reading comprehension skills. Word problem solvers problem effectively without understanding the word problem itself can not meet. The problem of what information is important to solve an equation? What information can be discarded? Distance, time and speed the pace of significant amounts of a car would be a problem are listed. The color of the car will have no effect in solving the problem.



2. Word problems in the field of algebraic expressions, or equations are applied. Good word problems and problem solvers is the value which is calculated, givens distinguish between. Givens always include both numbers and units. To calculate the value only one unit. Describe the measurement unit involved. 3. Successful problem solvers word science to see how statements are connected to each other in the mathematical expression. The example of how such a problem solver must complete? Sam at 40 kilometers per hour it green car rides. How far will it travel in 2 hours? A good strategy for using science, combined with measurement-related terminology to describe the number first to see, or what to do or the problem is known. Speed ​​can be measured in kilometers per hour. Time can be measured in hours. Phrase, hour and 2 hours 40 per km, are given or are known quantities in the example. Speed ​​and time are involved. Speed ​​is a ratio of distance and time. Word problem, a number without a value, or will contain unknown. Phrases or "how" much "or" what is "good for the price are clues. Unknown quantities distance, distinguished by the phrase "so far. His car, green, the color is irrelevant to solving the problem.



4. Successful problem solvers appropriate algebraic expression or equation to the problem, determine. For example, using the appropriate equation is: Speed ​​times time equals distance, or mathematical, d = speed * t. Now the problem is mathematical in nature. Time for the speed to 40 km per hour and 2 hours by replacement, is an answer to the problem solver 80 kilometers. Please note that the answer includes both a number and a unit. Algebraic equations by applying rules sometimes need to re-order all your sign on one side of the unknown quantity equals. 5. Successful problem solvers out their every move that he uses to solve the problem by writing the document the thinking process. The above example is rather basic, which most students can find out that their work without writing. Science word problems are the applications of science content. With more challenging science content, the same word problems, at first may seem very difficult. Simple steps below, which includes working out math problems in writing, breaking, often helps create success. Below each, unknown, equations, mathematical steps, and respond by writing, more challenging science word problems is less difficult. Problem solving process by applying the basic problems first, successful problem solver to soon introduce a more difficult word problems methods of science will develop.
