What are the planes of development in Montessori?
The planes of development are Maria Montessori's four six-year stages: 0–6 (early childhood, the absorbent mind), 6–12 (childhood, reasoning and imagination), 12–18 (adolescence, social identity) and 18–24 (maturity). Each plane has different needs, so Montessori designed different environments and roles for the adult at each stage.
What this means in practice
The planes explain why a 3–6 classroom looks so different from a 6–12 one, and why Montessori groups children in three-year age bands.
The four planes
- 0–6: physical independence; learning through the senses
- 6–12: intellectual independence; 'why' questions, group work
- 12–18: social independence; belonging and purpose
- 18–24: spiritual and moral independence; adult responsibility
For the 3–6 teacher
Your children are in the second half of the first plane: they need movement, order, real tasks and sensory experiences more than verbal explanations.
Practical next steps
- Learn the four planes.
- Note the needs of 3–6-year-olds.
- Plan activities for physical independence.
- Explain the planes to parents simply.
What to keep in mind
The planes are a framework; individual children vary.
