RATIONAL GAMES - THINK & FUN      This site contains games and more problems and is aimed as near the fun to learn that people will walk to judge, to consider the possibilities of resolving and know how to choose and to carry out the optimal variant. Readers recommend that after having learned one of the games proposed to deepen and explore logical deductions made as to solve the problem faster, as much as possible before meeting fellow! The site includes a very small part of the multitude of problems of this kind and was developed in order to present the project ThinkQuest MAP SITE PLAY MATHEMATICS: - DICE - Scope multimilenar game of chance, die offers many opportunies and rational amusement. To tackle the logic of this chapter is necessary to know the sum of any two opposite sides of the die is constant: 7. Exercises proposed dice to some concerns that some of the points have been removed or is no longer distinguishable. - MATCHES - Are presented on the nature of geometrical problems with sticks made the same lenght (matches). Resolution should respect as much as possible mathematical rigor through graphical representations of uniform segments, matches do not fold, don not break, he is not allowed opened figures, or those forced. ARITHMETICAL INTELLIGENCE:- The tests consisted here don't have the clame to be more than a game un joc. However one can say that some questions may be found in tests of general intelligence. TWIN FIGURES:- Games are presented rational aimed at splitting a geometric plane figures given in other figures equal. MAGIC CONFIGURATIONS: - It gives a geometrical figure composed of straight lines and curves are intersecting in the points (nodes). The problem consists of placing nodes in the figure of numbers so that the amount of numbers on each line and curve right to be always the same. Notations: N=no. whole to be placed, n=number of nodes, S=the amount constant, k=no.amounts, and no. straight lines and curves that make up the configuration,the ratio r = k / n, s= no. distinct solutions. CHALET GAMES: - Under this title are to be found some fun math, physics, of logic, philosophy, grammar all with common denominator the sagacious and sometime ingenuity and ability.
