Math joy. Learning through play | ||||||||||||||||||||||||||||||
The game is a universal activity that has been present in all cultures and has been very important development of mathematics. It is necessary to recognize its value as a means to learn and develop skills. Here's why. identifies the game as one of the six activities of the cultural environment that drive the development of mathematical ideas. The other five are counting, measuring, locating, designing and explain. According to him, the game promotes communication skills, poses challenges, creates uncertainty and develops mathematical reasoning. At the same time, involves defining rules, rhythms and harmonies, and lets you create an order. Research on some games has led to the creation of important mathematical theories. Recall that after solving a riddle, Leonhard Euler sat the foundations of modern and useful graph theory, that gambling began the study of probability, and that the famous mathematician John Nash (whose life was recreated in the movie A beautifull mind ) received Nobel prize for achievements in the study of noncooperative games. Therefore not surprising popularity mathematical interest showed by the study of puzzles, paradoxes, strategy games and other recreational events. class Playing In the classroom, the duly elected and dosed games are a new learning opportunity, and create an emotional and affective context for the development of mathematical ideas. With them is promoted mathematical reasoning in a natural and motivating, subtly takes students to investigate new techniques to solve problems, and developing these specific skills in strategic thinking, planning, decision making, estimation and demonstration. Also, when students play, low anxiety level, communication flows, the interest grows and the concentration remains. Besides all this, the teacher facilitates playful interaction the task of measuring the degree of understanding of concepts, the ability to implement certain knowledge, the ability to communicate ideas and arguments put forward. As we see, at every educational level games can advantageously replace some routine work for more active learning processes. Hence the value of including them in a consistent math program. What games use? When and how? an appropriate choice of games is a resource that every teacher must handle. Some countries have built playgrounds in schools or clubs of Mathematics, where students play and researcher from carefully selected materials. Periodically you can incorporate some game related to the topic you are trying to strengthen the capabilities and the concepts, and to assess student learning. The proposed classification can help make a proper selection of games for teaching:

THREE CATS
If three cats catch three rats in three minutes how many cats will catch 100 rats in 100 minutes? SOLUTION
The usual answer to this old conundrum is as follows: If three cats catch three minutes it takes three rats, should take a minute to catch, each rat. And if it takes one minute to catch a rat, then the same three cats hunt 100 rats in 100 minutes.
Unfortunately, it is so simple that answer certainly implies something that is not expressed in the problem. Assumes that three cats have focused their attention on the same rat to hunt in a minute, then set to devote another rat. But suppose that instead of doing that every cat hunts a rat different and will take three minutes to catch it. In that case, three cats, three rats continue hunting in three minutes. It would take six minutes to hunt six rats, nine minutes nine hunt rats, 99 and 99 minutes to hunt rats.
Now we face a peculiar difficulty. How long did it take those three cats hunt rats number 100? If they are still hunting three minutes boll weevil, so the three cats to hunt 102 minutes will delay the 100 rats. To catch one hundred rats in one hundred minutes - if that be the way that cats hunt their rat-certainly need more than three cats and less than four.
Of course, it is possible that when the three cats are concentrated on the same rat, may be cornered in less than three minutes, but nothing in the problem statement tells us how we can measure exactly the time that demand that operation. The only correct answer to the problem, then, is this: the question is ambiguous and can not be answered if there is no more information about how these cats hunt rats.
