Rallye Maths for the CM1 and CM2

Today was the Rallye Mathématiques for our fourth and fifth graders. They have been training for months in class with different exercises, problem-solving activities.

The Rallye Maths is a competition organized for French schools in the United States. It encourages students to work together to solve a few different problems and exercises, work also on negotiating as they have to discuss together to choose an answer; they might have to defend and justify their answers as peers might disagree.
