Glossary
Montessori, in plain English
Montessori has its own vocabulary, and most schools assume you already speak it. ‘Normalization’ in particular sounds alarming until somebody explains it. Here is every term you are likely to hear on a tour — 22 of them — written for parents rather than for trainees.

- Going outElementary children planning and taking their own trips into the community as part of their research.
- The Great LessonsFive big, dramatic stories told at the start of the elementary years to frame everything else.
The materials 4
- Sensorial materialsMaterials that isolate one quality — size, color, weight, sound, texture — so a child can refine their perception of it.
- Golden beadsGold-colored beads arranged as units, ten-bars, hundred-squares and thousand-cubes, used to make the decimal system physical.
- Pink towerTen pink wooden cubes, from one centimeter to ten, built into a tower by the child.

Teaching 3

The one that matters most
‘Montessori’ is not a protected word
Anyone in the United States may open a school and call it Montessori. That is precisely why the observable things — the work cycle, the age span, the materials, the training — matter more than the sign.
