Un site de France pour l'enseignement des mathématiques, avec des leçons (cours), exercices (avec correction), et exercices répétitifs de calcul mental. Plusieurs fichiers sont disponibles aussi en format PDF.

« Tout élève qui souhaite s'entraîner peut trouver dans ce site des exercices corrigés correspondants à sa classe.
Les niveaux 6e, 5e, 4e et 3e couvrent l'ensemble du programme. Il n'y a ni compétition ni enjeu. Une solution est disponible à tout moment. Ce n'est le plus souvent qu'une solution parmi d'autres.

*Sauf indication contraire, il faut donner la réponse des exercices interactifs, s'il s'agit d'un nombre décimal, avec une virgule. Dans les exercices répétitifs, les nombres sont générés par l'ordinateur, il faut écrire les décimaux avec un point à la place de la virgule.*

Les exercices et les résumés de cours sont signalés de la façon suivante :

-Un résumé du cours : En géométrie, les images mobiles ou les animations flash permettent de visualiser les notions abordées.
-Exercice corrigé : Des exercices pour s'entraîner, avec les corrections disponibles à tout moment. Mais d'abord il faut chercher ...
-Exercice interactif corrigé: On peut répondre directement sur l'ordinateur, mais une feuille de papier et un crayon sont le plus souvent nécessaires pour faire l'exercice entièrement.
-Exercice répétitif : calcul mental : Entraînement au calcul mental sur les techniques basiques à acquérir en mathématiques.

Attention : il faut toujours commencer l'exercice par "recommencer' ou "nouveau calcul" , l'exercice affiché à l'écran n'est qu'un exemple. Il n'est pas à tester ! »

The purpose of this task is to give 4th grade students a problem involving an unknown quantity that has a clear visual representation. Students must understand that the four interior angles of a rectangle are all right angles and that right angles have a measure of 90_ and that angle measure is additive.

Just as rigid motions are used to define congruence in Module 1, so dilations are added to define similarity in Module 2.  To be able to discuss similarity, students must first have a clear understanding of how dilations behave.  This is done in two parts, by studying how dilations yield scale drawings and reasoning why the properties of dilations must be true. Once dilations are clearly established, similarity transformations are defined and length and angle relationships are examined, yielding triangle similarity criteria.  An in-depth look at similarity within right triangles follows, and finally the module ends with a study of right triangle trigonometry.

Students learn about common geometry tools and then learn to use protractors (and Miras, if available) to create and measure angles and reflections. The lesson begins with a recap of the history and modern-day use of protractors, compasses and mirrors. After seeing some class practice problems and completing a set of worksheet-prompted problems, students share their methods and work. Through the lesson, students gain an awareness of the pervasive use of angles, and these tools, for design purposes related to engineering and everyday uses. This lesson prepares students to conduct the associated activity in which they “solve the holes” for hole-in-one multiple-banked angle solutions, make their own one-hole mini-golf courses with their own geometry-based problems and solutions, and then compare their “on paper” solutions to real-world results.

This 20-day module introduces points, lines, line segments, rays, and angles, as well as the relationships between them. Students construct, recognize, and define these geometric objects before using their new knowledge and understanding to classify figures and solve problems. With angle measure playing a key role in their work throughout the module, students learn how to create and measure angles, as well as create and solve equations to find unknown angle measures. In these problems, where the unknown angle is represented by a letter, students explore both measuring the unknown angle with a protractor and reasoning through the solving of an equation. Through decomposition and composition activities as well as an exploration of symmetry, students recognize specific attributes present in two-dimensional figures. They further develop their understanding of these attributes as they classify two-dimensional figures based on them.

The best part of teaching angles? They’re everywhere! Even in pasta noodles! This fun activity has students explore angles in a very engaging way.

The goal of this task is to use geometry study the structure of beehives. Beehives have a tremendous simplicity as they are constructed entirely of small, equally sized walls. In order to as useful as possible for the hive, the goal should be to create the largest possible volume using the least amount of materials. In other words, the ratio of the volume of each cell to its surface area needs to be maximized. This then reduces to maximizing the ratio of the surface area of the cell shape to its perimeter.

Este módulo de 20 días introduce puntos, líneas, segmentos de línea, rayos y ángulos, así como las relaciones entre ellos. Los estudiantes construyen, reconocen y definen estos objetos geométricos antes de usar su nuevo conocimiento y comprensión para clasificar las cifras y resolver problemas. Con la medida de ángulo que juega un papel clave en su trabajo a lo largo del módulo, los estudiantes aprenden cómo crear y medir ángulos, así como crear y resolver ecuaciones para encontrar medidas de ángulo desconocidas. En estos problemas, donde el ángulo desconocido está representado por una letra, los estudiantes exploran ambos midiendo el ángulo desconocido con un protractor y razonamiento a través de la resolución de una ecuación. A través de actividades de descomposición y composición, así como una exploración de la simetría, los estudiantes reconocen atributos específicos presentes en figuras bidimensionales. Desarrollan su comprensión de estos atributos a medida que clasifican las figuras bidimensionales basadas en ellas.

Así como se utilizan movimientos rígidos para definir la congruencia en el Módulo 1, se agregan dilataciones para definir la similitud en el Módulo 2. Para poder discutir la similitud, los estudiantes primero deben comprender claramente cómo se comportan las dilataciones. Esto se hace en dos partes, al estudiar cómo las dilataciones producen dibujos de escala y razonando por qué las propiedades de las dilataciones deben ser ciertas. Una vez que las dilataciones se establecen claramente, se definen transformaciones de similitud y se examinan las relaciones de longitud y ángulo, lo que produce criterios de similitud triangular. Sigue una mirada profunda a la similitud dentro de los triángulos rectos, y finalmente el módulo termina con un estudio de trigonometría del triángulo recto.
