## The bike lock

| Publish on September 19, 2022

Our Math Maestro, Jean François, is proposing a fun little riddle to revisit a couple of concepts. It can be done alone or in teams. The goal of this activity is to revisit students’ knowledge of the concepts of adding with carrying and subtracting with borrowing. You’ll love this fun approach to these concepts!

The activity includes a sheet for the students (The bike lock sheet), a virtual combination lock and instructions for the teacher to successfully carry out the activity in class.

Math Maestro Jean-François will have other, equally stimulating, activities for you during the year!
