It is common to see in our schools children writing the perfect theories in their notebooks that teachers successfully bring to the classroom. Months of hard work give account of a process characterized by the coldness of the calculations that implies having a notebook full of precise notes on the mathematics that must be taught in that specific grade. Many hours are invested by children, siblings and parents to carry out the tasks that the teacher has indicated in order to give an account of the theory that, in a precise way, without excess or default, the master has given impartially and beyond suspicion of error. Thus, in this context, in this reality, the school has been involved for several years now. decades (if not forever). However, few teachers, even few students, they still give themselves to the task of asking themselves sensibly: this ‒mathematics‒ as it is raised, What is it for? What is the purpose of learning these multiplication tables, just as they are in the board? What is factoring used for in my house? Who benefits from knowing the law of signs? Year after year, students are promoted from one grade to the next with the expectation that math in that grade to be at least not as scary of a challenge to overcome as the year before. Every year some students in our schools hope that the math teacher "won't put so much homework" and that "at least you can be understood to win the exam"
