Exemple d'exercice parmi les 54 exercices du chapitre

Pour réaliser la figure ci-dessous, on a défini un motif en forme de losange et on a utilisé l’un des deux programmes A et B ci-dessous.

Déterminer lequel a permis de tracer la figure.

Combien mesure l’espace entre deux motifs successifs ?

Pour cela on envisage d'ajouter l'instruction et de déplacer, si nécessaire, l'instruction dans le programme utilisé à la question 1.

Insérer ces instructions au bon endroit dans l'algorithme.

Exercice du chapitre suivant Revenir au choix du thème Revenir au choix du niveau

Kwyk vous donne accès à plus de 8 000 exercices auto-corrigés en Mathématiques.
Nos exercices sont conformes aux programmes de l'Éducation Nationale de la 6e à la Terminale. Grâce à Kwyk, les élèves s'entraînent sur du calcul mental, des exercices d'arithmétique et de géométrie, des problèmes et des exercices d'application, des exercices d'algorithmique et de python, des annales du brevet des collèges et du baccalauréat. Nos exercices sont proposés sous forme de réponse libre et/ou de QCM.

Afin d'assurer un entraînement efficace et pertinent aux élèves, chaque exercice est généré avec des valeurs aléatoires. Les élèves peuvent s'entraîner grâce aux devoirs donnés sur Kwyk par leurs professeurs et aux devoirs générés par notre outil utilisant l'IA mais aussi grâce aux différents modules de travail en autonomie mis à disposition sur leur espace personnel. Pour les niveaux du collège, les élèves ont également accès à des cours constitués d'une partie théorique et d'une partie pratique.
Avec Kwyk, vous mettez toutes les chances du côté des élèves pour que les différents théorèmes, propriétés et définitions n'aient plus aucun secret pour eux.

En 2024, plus de 40 000 000 d'exercices ont été réalisés sur Kwyk en Mathématiques.
