We don’t give answers. We build understanding.
Why Lulusolu?
Lulusolu was born from a simple idea: helping students make progress.
Here, corrections are not ready-made answers, but step-by-step explanations.
The goal is not to “do it instead of them,” but to give students the tools to succeed on their own next time.
Our approach
Clarity first: short steps, reminders of key rules, simple examples.
Independence: each correction helps the student complete the exercise by themselves.
Access for everyone: the website is completely free so that everyone can learn and improve, whatever their situation.
Respect for copyright: we do not reproduce exercises or statements from textbooks; only our own original content is published.
Users can purchase the textbook if they wish to see the original instructions.
Our ethical stance
We are firmly opposed to copying and all forms of cheating.
Corrections are meant for learning, not for copying.
What matters is reasoning, understanding, and progress.
In this sense, the answer itself is less important than the path that leads to it.
Who we are
Lulusolu is run by François and Magalie Tréca, former primary school teachers who became creators of educational websites.
We have developed several projects used daily by the educational community: SitesPE, Les Fichiers des Profs, MoteurPE, and LiloColors.
Lulusolu is the latest addition to this family of sites, with a clear focus: step-by-step educational corrections to help students understand.
A simple consistency
All our sites share the same goal: to make school life simpler every day.
SitesPE helps discover resources, Les Fichiers des Profs provides ready-to-use materials, MoteurPE saves research time, LiloColors offers coloring pages, and Lulusolu completes the set for students with clear, accessible explanations of their exercises.
Free and built to last
Lulusolu is free and funded by advertising.
We focus on simplicity, reliability, and everyday usefulness.
In short
No miracle promises — just well-crafted explanations, so that everyone can understand, think, and make progress.
We hope this website will be helpful to you 🙂
