Subject area
MATHEMATICS: “Verifying Transactions”
Educational objective
•Guiding students to discuss the artworks found on the EducArt platform about the theme of Transactions
•Collaborating with Secondary I students (Visual Arts) and Secondary II students (Mathematics) at the École du Royal-Roussillon
•Guiding students to find the value and the type of geometric transformation applied to the elements incorporated into the works created by the Visual Arts students at École du Royal-Roussillon in relation to an irregular shape created by the Secondary II students
•Guiding students to determine the actual size of an element chosen by the Secondary II students
Description of activity
Class 1: Once the project, its goals, the EducArt platform and the theme of Transactions have been presented, students take a look at the artworks related to the theme of Transactions found on the EducArt platform. Students watch the related videos found on the platform. Students complete a heuristic diagram based on the definition of the word “transactions.”
Class 2: Students revisit the works viewed on the EducArt platform and review the theme of Transactions. They discuss the creative projects completed by the Visual Arts students at École du Royal-Roussillon. They review their acquired knowledge about the concepts of area, percentage, ratio and geometry. For the assignment, the guidelines include the following: students must verify the precise calculation of an area and determine the percentage of a dominant colour in relation to the surface area.
Classes 3 and 4: In smaller groups, students develop a strategy to find the total surface area of a creative project completed by the Visual Arts students at École du Royal-Roussillon and the surface area of the dominant colours. They develop a strategy to find the percentage of the dominant colours in relation to the total surface of the creative project. They consolidate these strategies, step by step, in a tracing pad designed by the instructor. Using mathematical arguments, students justify that the percentage calculation was respected. They relate the value of the geometric transformation to the shapes produced by the students at École du Royal-Roussillon.
Class 5: Students produce and then position reproductions of the elements (geometric figures) in the right place on the cardboard surfaces, life-sized renderings of artworks found on the EducArt platform.
