Matheros is a digital learning platform from monecole.fr that helps primary school pupils develop mental calculation and problem-solving skills. Designed for levels CP to CM2, it organizes learning into a coherent progression while allowing each pupil to advance at an individual pace. The platform uses a superhero theme to make progress visible and engaging: pupils take on missions to liberate a city, and their hero evolves as they succeed in calculation activities.

Each new concept follows a structured sequence: pupils first learn through hands-on manipulation, then practise, play, and validate their skills. This approach gives meaning to mathematical operations before reinforcing accuracy through practice and repetition. Activities include mission maps, choosing the correct route, and head-to-head races. Teachers can personalize learning paths to suit pupils’ needs. Matheros is available by subscription, with pricing starting at €16 per year; access through GAR is offered via the monecole.fr shop. The site also provides contact, help, and account-login options for pupils and teachers.
