Overall, what makes this method of learning so different compared to the conventional form of education we have today, is that the teacher does not stand in front of the class and teach each child the same lesson all at once. Each child is allowed to learn at his/her own rhythm in a way where they feel as though they are in fact not learning or being taught.
Montessori called this way of teaching “preparing the child for success”. The teacher is there to guide your child through small Exercises in which your child will succeed. Through time, the Exercises rise in difficulty but because the progression is so well thought out, the child never feels as though learning is a struggle.
