See on the mapWhy this area comes where it does
An infant learns by looking, touching, mouthing, and listening. The visual mobiles come first because sight is what a newborn can use while lying on their back. Once the child sits, a treasure basket of real objects gives weight, texture, temperature, and sound to explore. Toddler materials then isolate one quality with two or three pairs, a simpler form of the 3–6 Sensorial materials.
It prepares the child for
- the Pink Tower, Color Boxes, and other 3–6 Sensorial materials
- matching and sorting
- exact words for what is seen, heard, and felt
- concentration
Visual Mobiles
4 worksFour mobiles hung one at a time above the awake infant on the movement mat, each giving the infant something to focus on and follow with the eyes during the first months.
Why this order
Young infants see strong black-and-white contrast first, then bright colors, then smaller differences in shade, then more complex movement (Montanaro 1991; Davies and Uzodike 2021). The four mobiles follow that order: black and white (Munari), three primary colors (Octahedron), five shades of one color (Gobbi), and shiny moving figures (Dancers). Each is used for a few weeks and replaced when the infant's interest drops. Once the infant reaches toward a mobile, visual mobiles are taken down and the hand-use mobiles in the Movement area (bell on a ribbon, ring on a ribbon) take over. The Munari starts at 1 month rather than 0.5 because the sources place it at about 3–6 weeks.
- SE T1.01Munari MobileA black-and-white mobile with a clear sphere, hung above the awake infant on the movement mat for looking at and following as it turns.
- SE T1.02Octahedron MobileThree eight-sided shapes of shiny red, yellow, and blue paper hung above the awake infant: the first mobile in color.
- SE T1.03Gobbi MobileFive spheres wrapped in thread of one color, graded from darkest to lightest and hung on a diagonal line above the awake infant.
- SE T1.04Dancers MobileFour human figures cut from light, shiny paper that move in the slightest air, hung above the awake infant as the last visual mobile.
Exploring with the Senses
3 worksCollections of real objects and outdoor materials the child handles, mouths, looks at, and listens to, with an adult nearby who does not direct the play.
Why this order
The treasure basket and heuristic play come from Elinor Goldschmied (Goldschmied and Jackson 2004) and are used in many Montessori infant rooms alongside the shelf works. The treasure basket is for infants who sit steadily but do not yet move far; heuristic play is for walking toddlers who fill, empty, and combine objects. Outdoor exploration covers the whole 0–3 period because the materials (grass, sand, water, leaves) stay the same while what the child does with them changes.
- SE T2.01Treasure BasketA low, sturdy basket of natural and household objects that an infant who sits steadily chooses from, handles, and mouths, while an adult sits nearby and does not direct.
- SE T2.02Containers and Collections (Heuristic Play)A set time in which a small group of toddlers fills, empties, stacks, and combines large collections of everyday objects and containers, then helps put them away by kind.
- SE T2.03Exploring Outdoors: Grass, Sand, Water, and LeavesThe child touches, sits in, digs, pours, and collects natural materials outdoors (grass, sand, water, and leaves) with an adult close by.
Size, Color, Shape, Texture, Sound, and Smell
13 worksToddler works that each isolate one quality (size, number, color, kind, shape, texture, sound, or smell) with few pieces, leading to the 3–6 sensorial materials.
Why this order
Size comes first because nesting and stacking show their own errors (a cup does not fit, a ring sits wrong) without any language. One-to-one placing follows. Color, kind, and shape use pairing and then sorting, which need longer attention. Touch, sound, smell, and the mystery bag come last because the child must work without relying on sight and hold one sensation in mind to compare it with another. Each toddler work uses 2–3 pairs or 3–5 graded pieces, fewer than the 3–6 material it leads to. Fabric Matching now also lists the 3–6 Fabric Box under preparesFor, because it is the direct next step.
- SE T3.01Nesting CupsThe child fits three graded cups inside each other from largest to smallest and takes them apart again.
- SE T3.02Graded Stacking RingsThe child puts graded rings onto a vertical dowel from largest to smallest.
- SE T3.03One for Each: An Object in Each CupThe child places one object in each cup of a row until every cup has one.
- SE T3.04Stacking Graded CubesThe child builds a tower of four wooden cubes from largest to smallest.
- SE T3.05Matching Colored ObjectsThe child pairs objects that are the same in every way except color, starting with two colors.
- SE T3.06Sorting Objects by ColorThe child sorts a mixed set of objects of two colors into two bowls, one for each color.
- SE T3.07Sorting Objects by KindThe child sorts a mix of two kinds of familiar objects into two bowls.
- SE T3.08Matching Shapes to OutlinesThe child places a circle, a square, and a triangle on matching shapes drawn on a card.
- SE T3.09Rough and SmoothThe child feels a rough board and a smooth board with a light fingertip touch and hears their names.
- SE T3.10Matching Fabrics by TouchThe child pairs squares of fabric that feel the same, starting with two very different fabrics.
- SE T3.11Matching Sound ShakersThe child pairs sealed shakers that make the same sound, starting with a loud pair and a quiet pair.
- SE T3.12Mystery Bag of Familiar ObjectsThe child reaches into a cloth bag, feels one of three familiar objects without looking, and takes it out to see what it is.
- SE T3.13Smelling Familiar ScentsThe child smells real foods, then pairs sealed jars that smell the same, starting with two scents.
