This document discusses strategies for improving achievement in math and science among disadvantaged students in France. It notes that while France historically produces many top mathematicians, recent performance on standardized tests is declining. The strategies proposed include using interactive tools like Geogebra and Scratch to make math more dynamic and fun, encouraging peer tutoring, linking math concepts to daily life, and sponsoring math contests to build interest. The goal is to help students learn to think mathematically and communicate their understanding.
