Mathematics: Geometry

Shapes and the arrangement of relative parts within a whole are the subject of geometry. Consider the construction of spider webs. The arrangement of petals forming a rose. Study the facade of a cathedral. The angles and the fitting together of its architectural elements. Or all the parts in myriad shapes that combine to make an automobile. Both the natural and the human-made environments are studies in shapes, angles, and intersections.

Best Shape Sorter Toys

Through observation and experience children learn about shapes and parts. First come basic shapes: round, square, triangular. Among early childhood play experiences are sorting and matching of shapes using a shape sorter. Simple ones are best for beginners, and Ambi Toys Lock A Block is best of class. High contrast between the bright white top and the color matched raised rims outlining each opening facilitates “hitting the target.” Equally importantly, its three dimensional shapes drop easily into place.

As shape discrimination, eye-hand coordination, and fine motor skills improve, children are ready for the next shape learning toys. Fitting two-dimensional shapes into corresponding holes. Sound Puzzle Box is a popular choice that rewards proper placement with distinct auditory responses.

Basic Shapes Puzzles 

Puzzles are all about shape. Again starting simple is key. Chunky shapes facilitate placement. Shapes that fit only in their proper places make a truly self-correcting learning experience. Left to right orientation models the direction of reading and writing. Children are ready to identify and match more unusual shapes only after they easily recognize basic shapes.

Interlocking Pieces Puzzles

After learning individual shapes through puzzles, children move on to explore the arrangement of shapes as parts of a whole. Start simple. The more pieces and the smaller the pieces, the more challenging a puzzle is. Wooden puzzles with thick pieces are easier for small hands to manipulate than thin cardboard ones.

A single layer, wooden 8-piece fish shaped puzzle for toddlers, Rainbow Fish, invites exploration of color and shapes and the way parts fit together to make a whole. With only one way to complete the puzzle, the child has to sort out and make sense of the pieces. Then work out how the parts go together to create the whole, a sometimes frustrating experience that benefits from adult encouragement.

Layered Puzzles 

Layered puzzles introduce perspective and offer graduated challenges. As always, start simple and progress gradually. More layers offer more challenge; however, the number of pieces is a more accurate indicator of difficulty.

Mathematical Concepts Puzzles 

Although most puzzles go together in one and only one way, others offer options, and these literally open doors to understanding of mathematics.

The Binomial square wood puzzle introduces mathematical concepts through observation and experience. Children develop proportional reasoning, area concepts, and place value understanding when they discover four small squares cover the same area as the rectangle and four rectangles the same as one large square. And that’s only the beginning of the possibilities.

Power of Two Puzzle encourages experiential learning of important mathematical ideas from fraction equivalents, fraction multiplication with a common factor of 1:2, proportional reasoning, and area. The 10 puzzle is cut into one-half, one-fourth, one-eighth, one-sixteenth up to 1/128th. Clearly challenging, the beauty of Power of Two lies in the multiple ways the pieces can fit together and the arrangement of relative fractions.

Tips for Selecting Shape Sorters

Remember the expression “a square peg in a round hole”? Immediately we understand what’s being said; someone is a misfit, an individual who does not fit within a specific group. The observation creates a visual impression. We see in our mind’s eye the misfit between a square peg and a round hole. Perhaps because as toddlers we played with one or more shape sorters and learned to “post” shapes into their corresponding spaces.

Shape sorters take many forms, and what works well for one child might not be the best choice for another. When considering shape sorters, remember that toddlers are just beginning to distinguish shapes. Limit shapes to basic ones: circle, square, triangle. The goal is to balance challenge with the likelihood of success. Acquiring skills is an ongoing process that moves forward with experience, repetition, and incremental success.

Shape sorters develop eye-hand coordination, fine motor, cognitive, and language skills. Rewarding matching with a distinctive sound also develops auditory awareness and discrimination. Value-added features expand play possibilities.

Children need to feel competent and confident of their skills before moving on to the next level. If a toy is too complex, the child will avoid it, and we will need to “walk backwards in our minds” to identify the missing link between where she is now and the activity we’ve offered.

With discriminating shapes, stepping back means assessing multiple skills. Does she easily grasp and release? Does she relish every opportunity to” fill and spill”? Are her eye-hand coordination and fine motor skills well developed enough for her to fit a peg in a hole? These activities come before posting shapes. The Classic Pop Up Toy is an engaging, traditional wooden toy featuring four peg figures that pop up and down on concealed springs as the child presses one after another. The removable figures can be color matched to stripes on the front of the box but that’s optional. The focus is on developing eye-hand coordination and fine motor skills required for successful posting. Matching colors and shapes are a next step.

Ambi Lock A Block is my favorite shape sorter. Features that make Lock A Block most successful to Raised rims make sorting shapes easierbeginning sorters also make it a must for inclusive play. Unique attributes that support success in identifying and matching primary colors and basic shapes include high contrast between white top and color matched, raised rim openings and three dimensional shapes that drop into place more readily than shaped dowel pieces. Retrieving shapes by unlocking a door on the front of the block adds another dimension to play. The permanently attached key fits smoothly in the lock and turns easily. The lock clicks as the key turns, adding auditory input.


3-shapes sound emitting shape sorterA perennial favorite among the blind and visually impaired is Hooty-Hoo Shape Sound Sorter. Each shape makes a unique sound as it slides down its clear tube. The basic shapes – circle, square, and triangle – require more precise fitting than the three dimensional ones in Lock A Block, but the auditory response rewards the persistent. For children needing tactile re-enforcement, the openings for the shapes can be outlined with a Wikki Stix. When no longer needed, Wikki Stix peels off easily. Retrieve the shapes by turning Hooty-Hoo Shape Sound Sorter upside down.

When choosing a shape sorter, consider the child who will be playing with the toy. Once you’ve figured out the appropriate skill level, you’ll be able to choose confidently.
