Browse Montessori materials by plane, at your own pace

How do I browse Montessori materials by plane in the app?

The Montessori materials by plane catalogue lives under Suggestions, in the Materials tab. Open it and browse. Heart what catches your eye. If you want to track one, tap Add to my library and it lands in your Materials shelf with a status of "stored." That is the whole interaction.

You are not behind on materials

If you opened this tab and felt a flicker of panic at items you have never heard of, that is a normal reaction. The catalogue is not a checklist. It is a curated reference, filtered so you only see materials that fit your child's current developmental plane (the broad stage of development they are in, such as birth to six or six to twelve). You are not seeing everything. You are seeing what is relevant right now.

Most families doing Montessori at home own a handful of materials and improvise the rest. If you are working with a tight budget, a single set of measuring cups and a bag of dried lentils covers more ground than you might expect. The buying guide linked at the bottom of this article covers the full cost spectrum, from charity-shop finds to specialist suppliers.

What does each card show?

Each card in the Montessori material library shows the material's name, its curriculum area, the typical age range, and a short developmental description (no price, no sales pitch).

Every material card in the catalogue includes four things:

• Name, such as Pink Tower (a set of ten graduated wooden cubes a child stacks to isolate a single quality: dimension).
• Montessori area, such as Sensorial (the curriculum area focused on refining the senses through structured, hands-on materials).
• Age range, based on when children typically reach for the material.
• Short description of why a child is drawn to it, written in developmental terms rather than marketing language.

The description is there to help you understand what the material does for a child, not to persuade you to buy it.

Why does the order of Montessori materials by plane matter?

Canonical Montessori materials are sequenced so that each one builds indirect readiness for the next, and the plane filter keeps you looking at the right portion of that sequence.

Montessori materials follow a principle called isolation of difficulty (each material isolates a single quality the child is sensing, so no other variable changes at once). They are sequenced so that mastering one prepares the child indirectly for the next. A child who has worked with the Pink Tower, for example, is building readiness for the Brown Stair (ten graduated prisms isolating width).

That chain continues: the Brown Stair leads to the Red Rods (ten graduated rods isolating length), and eventually to Number Rods (rods that add quantity to length).

This sequencing means buying materials in a random order can leave gaps that confuse a child. The catalogue helps here: because it is filtered by your child's developmental plane (Plane 1, roughly birth to six, or Plane 2, roughly six to twelve), you are already looking at the right portion of the progression. You do not need to memorise the sequence yourself.

If you can only afford one or two items this term, that is completely fine. One well-chosen material in daily rotation does more than a full shelf of unused ones.

What can I do with a material I like?

You can heart it to save it as a favourite, or tap "Add to my library" to drop it into your Materials shelf with a default status of "stored."

Two actions are available on each card:

1. Heart it. This saves the material as a favourite so you can find it again quickly. It does not add it to your library or commit you to anything.
2. Add to my library. This drops a copy of the material into your own Materials shelf with a default status of "stored." Stored means "I know about this and I might get it." It is a placeholder, not a purchase order.

Once a material is in your library, you can change its status at any time: on shelf, in rotation, stored, or retired. The materials shelf is where you track what you actually own and use. For more on that, see the materials shelf tracking article linked below.

A Tuesday evening in Barnsley

Gemma is a single mum who works part-time at a supermarket. Her daughter is five. After bedtime stories and a cup of tea, Gemma opens Willowfolio on her phone and taps into the Materials tab.

She scrolls through a few cards. The Pink Tower catches her eye because her daughter has been obsessed with stacking things. She hearts it. She also spots a set of Sandpaper Letters (textured letter shapes a child traces to learn letter formation through touch) and thinks that might be good for next term.

She taps Add to my library on the Pink Tower because she has already been putting a few pounds aside. The Sandpaper Letters get a heart for later.

That is all. Two minutes, one addition, one favourite. She closes the app.

If your evenings do not look like Gemma's, because you are juggling shift patterns, co-parenting handovers, or simply too tired to think about materials tonight, the catalogue will be there when you are ready. There is no expiry on any of it.

The catalogue is a reference, not a shopping list. Browse when you feel like it, close it when you do not. If something feels off or you have a question, email us at [email protected].
