The Inscribed And Concentric Figures: Plastic is a Educational Materials Montessori material designed for children aged 3-6, crafted by Nienhuis Montessori to AMI standards.
This Inscribed and Concentric Figures material introduces children to the concept of nested shapes through hands-on exploration. The wooden tray holds three plastic geometric puzzles featuring concentric designs - squares within squares, circles within circles, and a playful triangle variation - allowing children to discover size relationships and develop visual discrimination skills essential for later geometry work.

The Inscribed and Concentric Figures puzzle addresses children's developmental need to understand spatial relationships through direct manipulation. Each plastic shape in this material can be physically nested within its larger counterpart, allowing children to discover that a small square fits perfectly inside a medium square, which fits inside a large square. This concrete experience with the concentric designs prepares the mathematical mind for abstract concepts of area, perimeter, and proportional reasoning. The three distinct puzzle formats - squares, circles, and triangles - provide varied geometric experiences within one wooden tray. Through repeatedly removing and replacing these plastic shapes, children internalize the concept of concentricity while refining their visual discrimination. The material's design isolates the concept of size gradation within identical shapes, eliminating distractions and focusing attention on the mathematical relationship between the nested figures.
Each order includes everything needed for proper presentation and long-term use.
Follow the Montessori method of presentation for optimal child development.
Remove all pieces from one puzzle section, placing them randomly on the mat
Select the largest shape and trace its edge with your index finger
Place the largest shape back in its frame depression
Continue with progressively smaller shapes, nesting each inside the previous
Invite the child to try with another puzzle section
Each material supports multiple areas of child development simultaneously.
Distinguishing between sizes and shapes refines perception skills crucial for reading and mathematics.
Hands-on exploration of concentric shapes introduces fundamental geometry principles through concrete manipulation.
Precise placement of nested pieces develops pincer grip and hand-eye coordination.
The self-correcting nature of the puzzles encourages sustained focus and problem-solving persistence.
Designed for child-sized hands
Professional tips from AMI-trained guides to maximize the educational value of this material.
“Present one puzzle type at a time initially, allowing mastery before introducing all three”
'This circle fits inside' rather than 'goes in'
Create extensions by having children trace removed shapes to see size relationships on paper
Connect to practical life by finding concentric examples in the environment (tree rings, ripples)
Everything you need to know about this material.
This material is designed for children ages 3-6 years old, aligning with the Montessori sensorial curriculum for the primary classroom.
The set includes three plastic geometric puzzles featuring concentric designs: squares within squares, circles within circles, and a triangle variation, all housed in a wooden presentation tray.
Children develop visual discrimination, size relationships, and spatial awareness through hands-on exploration of nested shapes, building foundational concepts for geometry, measurement, and mathematical reasoning.
Children develop fine motor control, hand-eye coordination, visual perception, concentration, and problem-solving skills while learning to distinguish between different sizes and understand the concept of shapes fitting within shapes.
Begin by showing how to carefully remove each piece from largest to smallest, then demonstrate replacing them in order. Use precise language like 'large,' 'medium,' 'small' and allow the child to explore independently after the initial presentation.
