TN - Triângulo Numérico

The teaching of mathematics needs to be stimulated so that the students can assimilate the commutativity and associativity of adding some number sequences in a playful way. In order to support the teaching of mathematics, several games have been used by educators to provide understanding. The Numeric Triangle, besides providing understanding of the content, assists in logical reasoning in a fun way. It can be used as a playful activity in the classroom for students of final years of elementary school or as a logical and mathematical reasoning activity for any level of education that knows the content algebraic sum with minimum requirement. The screen will display six numbers that correspond to a numerical sequence (can be positive and negative numbers) within circles for manipulation through the touch of the phone or tablet. In the triangle that is positioned in the center of the screen with a center value that means the result of the sum of the numbers inserted in the circles on each side of the triangle, the player selects each circle containing a number in a numerical sequence and can position in its proper place in each side of the triangle, and on each side of the triangle must have the combination of numbers to be summed and compared to the result of the central value of the triangle and thus using intuitively the properties of commutativity and associativity of addition.
