Défi Relatifs

Défi Relatifs, published by the Academy of Dijon, is an interactive Chrome extension designed for Cycle 4 students to practice calculations involving relative numbers. It offers customizable exercises including addition, subtraction, multiplication, and division with options for direct or gap-fill calculations.

The extension features two engaging game modes: Single Player mode where students practice independently with immediate feedback and performance summaries, and Challenge mode where two players compete by answering faster and more accurately. Users can adjust parameters such as response time, number of questions, types of operations, and difficulty levels (easy, medium, hard) to tailor their learning experience.

With the option to create user accounts, learners and educators can monitor progress through detailed reports. Défi Relatifs serves as a powerful tool for mental calculation training, differentiation, and competitive learning, making math practice dynamic and motivating.
