A Montessori classroom doesn't move through a shared lesson plan — every child works through the same scope and sequence at their own pace. Presented, Working, Mastered is the shorthand guides use to record where each child stands on each material, across practical life, sensorial, language, mathematics, and cultural work.
The three states
- Presented.The guide has given the child a lesson on this material — usually a three-period lesson — introducing its name, purpose, and correct use. Being presented doesn't mean the child has learned it; it means the door is open.
- Working. The child chooses the material independently and practices it, with or without full accuracy. This is the longest state for most materials — repetition is how the concept is internalized, not a single successful attempt.
- Mastered. The child uses the material correctly and independently, consistently, without guide support. For many materials, mastery also means the child can explain or demonstrate the underlying concept, not just repeat the motion.
How to decide when a child has moved states
Move a material from Presented to Working the first time you see the child choose it on their own — you don't need to wait for a formal check. Move it to Mastered based on observed independence over multiple sessions, not a single clean pass; a child who gets it right once under close attention hasn't necessarily internalized it. This is where a good observation log pays off — you can look back at several dated notes instead of relying on memory at conference time.
Tracking progress across a full classroom
The hard part isn't tracking one child on one material — it's doing this for 20+ children across hundreds of materials, all at once, without losing the thread. Most guides keep a matrix: materials down one axis, children (or a child's own sheet) down the other, with a date recorded for each state transition. On paper, this is exactly what our free progress matrix template is built for.
The matrix answers two different questions depending on how you read it: read down a child's column and you get their individual work plan for tomorrow — what to present next, what needs more practice time. Read across a material's row and a school leader can see who in the room hasn't touched a key material yet, which is much harder to spot from a stack of individual observation notes.
Where digital tracking helps
A digital progress matrix does the same three-state tracking, but a leader can see coverage gaps across every classroom without walking the halls, and a guide can update a child's state from a tablet on the floor instead of returning to a desk. msphere logs Presented, Working, and Mastered per material per child, tied to the same observations and portfolios families see — see the full picture on the Montessori record keeping page.
