"Acquire the fundamentals thanks to the best teaching practices of Europe, such is the will of the partners of this project.A report by the French mathematician Cédric Villani speaks of ""a feeling of self-deprecation among the students and the adults"", as early as 7 years of age, the pupils already declare themselves ""rubbish at maths"" but the aversion for maths is by no means a fatality.We want to desacralize mathematics, and make it a domain, a subject, a teaching matter like any other by offering our pipils learning strategies, formal or informal mathematical openings that are adapted to the needs of each of them.We must therefore develop in our pupils' heads a critical and scientific spirit, leading them from the concrete to the abstract.To achieve this, it seems important and necessary to train all the actors and stakeholders to move from a passive learning mode to an approach based on the constant development of the teacher to reverse the curve of the pupils' results during the assessments in mathematics and ""bring back together"" the individual with mathematics."
