Practical Life activities in a Montessori classroom assist the child to control and coordinate their moments, and one of the earliest activities introduced in a 3-6 classroom is called “Walking on the Line”. Montessori saw this as a natural extension of something children liked to do (walking on curbs or tracks) and developed the activity not only to help them control their body, develop balance and perfect equilibrium, but to strengthen the mind’s control of its body’s movements.
