The method

Why these materials, in this order.

Montessori is not a set of wooden toys. It is a set of observations about how children under six actually learn, and the materials follow from them. These are the five ideas that do the most work — once they make sense, the rest of this site is mostly bookkeeping.

The absorbent mind
Montessori's name for a young child's capacity to take in their surroundings whole, without effort and without choosing to. She divided it in two: unconscious from birth to three, conscious from three to six. The practical consequence is that under three a child absorbs the environment as it is — so the environment is the lesson, and arranging it is most of the teaching.
Sensitive periods
Windows when a child is unusually drawn to one kind of learning — movement, order, language, small objects, refinement of the senses, social grace. A material offered inside its window is met with startling concentration; the same material a year early is a frustration and a year late is furniture. This is why sequence matters so much in the first three years.
The prepared environment
A room arranged so the child can act without asking: materials at their height, few things out at once, everything in a fixed place, and nothing that restricts how they move. AMS describes it as calm, homelike and ordered, with muted colour and space to work undisturbed.
Control of error
The material itself tells the child when something is wrong, so an adult does not have to. A cylinder left over at the end of the cylinder block is unambiguous feedback that carries no judgement, which is why children will repeat these materials far past the point an adult would have corrected them into giving up.
The work cycle
Choose the work, do the whole of it, put it back. AMS lists the uninterrupted work period as a core component of the method, and the uninterrupted part is doing real work: concentration is what is being built, and a child deep in a task is doing something you should be slow to break into — including with praise.
