Calculatice

Calculatice (also known as calcul@TICE) is a free educational platform developed by the French National Education system to help children improve their mental math skills through interactive games and exercises. The platform is specifically designed to make arithmetic practice engaging and enjoyable while strengthening mathematical fluency, number sense, and problem-solving abilities. It is widely used by teachers, schools, and families throughout France as a supplement to classroom learning. Unlike many general educational websites, Calculatice focuses almost exclusively on mental mathematics. Students can practice addition, subtraction, multiplication, division, fractions, geometry, and logical reasoning through hundreds of interactive activities organized by age and difficulty level. Teachers can also create personalized learning paths, track progress, and organize nationwide mental math competitions known as "Rallyes." Nearly 150,000 students participate in these challenges each year.
