In 3rd grade geometry, the students are studying a very unique figure: the circle. In addition to learning to manipulate a compass, they are asked to understand the concept of “the circle”.
Marie-Pier (math coordinator) and Murielle organized an activity for the students to help them better understand what a circle is.
Placing a gift on the ground, they asked all the children to stand at the same distance from the gift.
After several attempts, they naturally found that the best configuration was that of a circle.
In class, the pupils also quite naturally found the definition of the circle: a set of pupils placed at the same distance from a gift also defined as a set of points equidistant from the center.
