Description
Key Purposes & Benefits
-
Logical Classification: The Child must identify a common attribute (color, shape, size, or type) and group objects accordingly.
-
Order and Concentration: Sorting is an inherently calming activity for toddlers. It satisfies their “sensitive period for order” by allowing them to create harmony out of a scrambled pile of objects.
-
Visual Discrimination: It sharpens the eye to see subtle differences and similarities between objects.
-
Fine Motor Control: Moving small objects between compartments using a pincer grasp (or sometimes wooden tongs for older toddlers) strengthens the hand muscles.
Structural Design
-
The Tray: A Birchply tray divided into 4 compartments, and a control area
-
The Objects: Items should be clearly different in one attribute but similar in others (to “isolate the difficulty”). Common sorting items include:
-
By Color: Red, blue, and yellow wool balls.
-
By Nature: Large smooth stones vs. rough pinecones vs. seashells.
-
By Shape: Wooden spheres vs. wooden cubes.
-
How to Present the Material
-
Set the Stage: Place the tray on a rug or table.
-
The First Item: Pick up one item (e.g., a seashell). Place it in the first compartment.
-
The Contrast: Pick up a different item (e.g., a stone). Place it in the second compartment.
-
The Sorting: Pick up a second seashell. Look at it, look at the stone, then look at the first seashell. Place it with its match.
-
Turn-Taking: Once you have sorted two of each, invite the child to finish the rest of the objects.
Variations of Sorting
As the Child grows, the difficulty of the sorting tray can be increased:
-
Two-Way Sort: Simple categories (e.g., “Big” and “Small”).
-
Three-Way Sort: Introducing a third category (e.g., “Red,” “Yellow,” and “Blue”).
-
Functional Sorting: Sorting household items (e.g., “Spoons” and “Forks” when helping set the table).
-
Tool Use: Adding tongs or a large spoon to move the items, which adds a layer of practical life skill and coordination.
The Logical Sequence
-
Imbucare Box with Bins: Sorting into hidden compartments.
-
Sorting Tray: (This material) Sorting in an open, visible field.
-
Abstract Sorting: Sorting pictures of objects rather than the physical objects themselves.
Size: 26 x 20 x 2.5 cm / (10″ x 8″ x 1″)

Transferring by Catherine McTamaney

It’s a sort of curious activity to watch: a young child, mesmerized, repeatedly transferring some small object from one container to another and back again. Fill the containers with pom poms or small rubber pellets. Maybe the tongs are large and wooden or m…
