Hi, and welcome! I’m Vincent Tariel, the sole creator of CommeUnJeu — a personal project born from my passion for playful learning and creative exploration.

This site is designed to offer simple, engaging activities that feel more like games than work. Whether you're using it for teaching, parenting, or your own inspiration, I hope you find joy in it.

Most math platforms are libraries of fragmented content; CommeUnJeu is a unified data architecture. The core of the project is the “Data” — the structured lessons themselves. Every lesson is authored within a single, coherent pedagogical thread across all grade levels, so ideas evolve logically, vocabulary stays consistent, and progression is intentional.

This continuity means that a student encountering functions early on is building on the same conceptual foundations they will rely on years later for advanced study. CommeUnJeu is not just a website; it is a complete mathematical learning journey mapped as a continuous, connected dataset.

All content on CommeUnJeu is available for personal use only. Please don’t reproduce or distribute materials for commercial purposes.

If you want free knowledge, please share this project with your network.
