Numération et groupement
Read full descriptionHide full description
Cette application permet de comprendre la numération décimale (unités, dizaines, centaines, milliers) en manipulant concrètement différents matériels. L’onglet “Paramétrage” en bas de l’écran permet de choisir un type de représentation : cubes, boules, nombres en chiffres, nombres en lettres... On peut alors effectuer des groupements par dix, cent, mille, sélectionner ou désélectionner des blocs, ajouter ou supprimer des objets, etc. Ces modifications apparaissent dans le tableau de numération affiché à l'écran. Des outils interactifs d’annotation permettent de tracer des lignes et des formes, d'ajouter des dessins et schémas, ou d'écrire des commentaires. L'application est très utile pour s'approprier le système décimal. Elle convient à tous les niveaux de l'école primaire.
Calcache, Math facts puzzles
Read full descriptionHide full description
Rediscover mental math in a game that is both playful and smart. Far from repetitive quizzes, Calcache offers an original approach to anchor addition and multiplication tables in memory: the classic "Word Search" principle, adapted for numbers. A Subtle Game Mechanic: In a seemingly random grid of numbers, your child must spot and trace valid equations. This visual search exercise stimulates observation and logic, transforming revision into a genuinely stimulating brain teaser. Why Calcache Stands Out: - A Unique Concept: The only game that blends the soothing mechanics of Word Search with the rigor of mathematics. - Teacher-Approved: A method validated by educators for its effectiveness in memorization and mental agility. - Gentle Progression: The game adapts to the child's pace, unlocking tables (from 2 to 9) as they succeed, maintaining interest without frustration. Designed to Last (Ages 6 to 11): Whether introducing addition to younger children or reinforcing multiplication for older students, Calcache offers a moment of playful concentration—ideal for homework help or quiet time. With Calcache, your children will master mental math and actually ask to practice!
