Because something you may or may not know about truly authentic Montessori programs is that students are usually self-paced and self-directed when it comes to their lessons. What that means is that, first of all, if they’re learning something new, they have what is called a “presentation” with their teacher, which is usually done one-on-one with the teacher, or with a very small group. But, aside from presentations, which are scheduled, students usually decide for themselves what they are going to do — what lesson they want to work on first, what activity they’re going to do next, etc. So there’s a lot of freedom given to the students, and that’s actually one of the hallmarks of the Montessori pedagogy. Students are trained to take initiative, to be independent, to own and take responsibility for their time.
