how a general thinking of mathematics, and not strictly divided by the sub-fields of numeracy and geometry, would allow the maternal pupil to evolve in discipline over cycles, giving meaning and interest in learning? We will start this study with an overview of current mathematical curricula, in the core learning cycle. We will analyse various documents from institutional and educational resources and try to identify the imbalance between the two digital and geometric sub-domains. As a second step, we will seek to develop an overview of mathematics by proposing a project, with geometry and markers in space as the dominant feature, which can be set up in a small section class. We will also explore its interdisciplinary capabilities and limitations. Finally, we will try to draw general aspects of the teaching of mathematics.
