The SDM 2025 application is intended for use in a school (primary school or middle school) as part of mathematics week. It allows the setting up of a puzzle competition, under the supervision of a reference teacher who collects the answers and establishes one (or more) rankings.



FUNCTIONING :

The puzzles are available from March 12, 2025. Every day, from midnight, the daily puzzle is unlocked and can then be solved. Each puzzle has four levels of increasing difficulty. In general, level 1 is easy and allows you to understand the operations to be carried out. Level 3 is difficult for primary school students, who will most often be able to solve level 2.




PROCESSING RESPONSES:

The answers must be sent to the organizing teacher(s), but not to the author of the application! The answer to be given is in the form of a screenshot, to be sent by email to the address indicated in the organization of the puzzle competition. The application does not offer correction of answers
