Le présent guide vise à soutenir les enseignants de l'élémentaire et du secondaire dans l'enseignement des compétences de base en statistique. Il fournit aux enseignants des instructions précises pour les aider à :
- trouver des ensembles intéressants de données canadiennes qui répondent aux besoins des différents niveaux scolaires;
- choisir les diagrammes convenant à différents types de données;
- calculer des mesures statistiques de base avec l'utilisation ou non de logiciels.

Les élèves apprendront dans la présente leçon des modes d'application de la forme canonique [y = a(x – h)2 + k] d'une équation quadratique. Ils extrairont de la base de données E-STAT de Statistique Canada des données sur le nombre d'hommes inscrits à des programmes d'apprentissage au Canada et ils les importeront dans un logiciel de statistique. En rajustant les valeurs des paramètres a, h et k afin de maximiser l'ajustement de la parabole aux données sur le nombre d'hommes inscrits à des programmes d'apprentissage, les élèves modéliseront une équation quadratique dans le logiciel. Ils acquerront une meilleure compréhension du rôle des paramètres dans la forme canonique d'une équation quadratique.

In this article Judi and Harley illustrate the seven frieze patterns using art of the indigenous peoples of North America. They then develope some of the mathematics of frieze patterns at a level that is accessible to many students. The teacher notes contain activities with frieze patterns for students at all levels.

This article is part of the Mathematics Notes series at Washington State University. In the article, Judi and Harley start by determining the functions that map the plane back onto itself, while at the same time, mapping a specified line back onto itself and preserving the size and shape of any objects represented in the plane. These are the functions that preserve frieze patterns. The authors then look at the algebraic structure of this collection of functions under the operation of composition, show that there are only seven frieze groups, and illustrate how they are generated. Each frieze group is represented algebraically and geometrically. The article concludes with a tour of the Washington State University campus, looking at the ways in which frieze groups are exhibited and used in our immediate surroundings.

In the real world, graphs related to human population or socio-economic statistics rarely approximate any mathematical functions other than linear functions. However, there are some occasions where the underlying conditions lead to trends which closely approximate quadratic, exponential, sinusoidal, and logistic functions.

This one of the articles in the seventh edition of Ideas and Resources for Teachers of Mathematics, a newsletter published by the Saskatchewan Mathematics Teachers' Society. The theme of the seventh edition is patterning and algebra and in this article Alain shows how experiments can be used to make connections between formulas and real life situations.

In this lesson, students will learn about applications of the vertex form [y = a(x – h)2 + k] of a quadratic equation. Students will extract data on the number of males registered in apprenticeship programs in Canada from Statistics Canada's E-STAT database and import them into a statistical software program. Within the software program, students will model a quadratic equation. By adjusting the values of the a, h, and k parameters to maximize the fit of the parabola to the data on the number of males registered in apprenticeship programs, students will gain a greater understanding of the role of the parameters in the vertex form of a quadratic equation.
