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.

A diamond slope, or the slope of the angle bisector, is considered in this note as a generalization of two well-known slope relationships. This general approach is compared then with well-known approaches using various examples.

Gregory and Oleksandr have built on the arc midpoint resource and the proof of the arc midpoint formula by constructing an algorithm for finding the coordinates of the midpoint. It is hoped that teachers of high school Mathematics and Computer Science will use these resources to enrich the teaching and learning in both subject areas.

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.
