The Partes De Lo Entero is a Educational Materials Montessori material designed for children aged 3-6, crafted by Nienhuis Montessori to AMI standards.
This Partes De Lo Entero (Parts of the Whole) material introduces children to the fundamental concept of fractions through engaging visual cards featuring everyday objects. Each laminated card pair shows a complete object alongside its divided sections, helping children understand how wholes can be divided into equal parts through concrete, relatable examples.
“The child is both a hope and a promise for mankind.”— Maria MontessoriEducation and Peace
“The hands are the instruments of man's intelligence.”
— Maria Montessori, The Absorbent Mind
Partes De Lo Entero bridges the gap between concrete experience and abstract mathematical thinking by presenting fractions through familiar objects from daily life. The laminated card pairs showing whole objects alongside their divided sections allow children to discover fraction concepts through visual comparison rather than numerical symbols. This material addresses the developmental need for concrete representation before abstraction - children can see an apple cut in half or a pizza divided into quarters, connecting mathematical concepts to their lived experiences. The everyday objects featured on these cards make fraction work accessible because children already understand these items intuitively. By working with Partes De Lo Entero, children build mental schemas for division and proportional reasoning through images they can relate to their own experiences. The visual nature of these fraction cards respects how young children process information - through observation and comparison rather than abstract rules.
Each order includes everything needed for proper presentation and long-term use.
Follow the Montessori method of presentation for optimal child development.
Invite the child to examine a whole object card, naming the familiar item shown
Show the corresponding divided card, tracing the division lines with your finger
Place the matching cards side by side, allowing visual comparison
Continue matching remaining pairs, discussing how each whole divides
Mix the cards and invite the child to create matches independently
Every material is carefully selected for durability, safety, and authentic Montessori experience.
Sourced from sustainably managed European forests. Beechwood is chosen for its exceptional durability, smooth grain, and natural warmth that invites touch.
Natural, unbleached cotton in child-friendly colors. The fabric provides the right amount of friction for developing fingers while being gentle on sensitive skin.
Water-based, child-safe finish that meets the strictest European safety standards. Designed to withstand years of daily use without chipping or peeling.
Each material supports multiple areas of child development simultaneously.
Introduces fraction concepts through concrete visual representations of parts and wholes.
Develops ability to recognize relationships between complete objects and their divided sections.
Encourages analysis of how objects can be divided into equal parts through matching activities.
Builds vocabulary for mathematical concepts including whole, part, half, and quarter.
Designed for child-sized hands
Professional tips from AMI-trained guides to maximize the educational value of this material.
“Present simpler divisions (halves) before complex ones (sixths or eighths)”
Connect card work to snack time - actually divide foods shown on the cards when possible
whole, divided, and fraction symbol for advanced students
Use the cards for group lessons on fair sharing and equal distribution
Everything you need to know about this material.
This material is specifically designed for children ages 3-6 years old, aligning with the sensitive period for mathematical concepts during the preschool and early elementary years.
The material uses visual card pairs showing familiar objects (like fruits, pizzas, or shapes) in their whole form alongside the same object divided into equal parts, making abstract fraction concepts concrete and relatable.
The set includes multiple pairs of laminated cards featuring various everyday objects. Each pair consists of one card showing the complete object and another showing it divided into equal parts (halves, thirds, quarters, etc.).
Yes, after an initial presentation, children can work with these cards independently. The visual nature and self-correcting aspect allow for autonomous learning and exploration of fraction concepts.
By introducing fractions through concrete visual representations, children develop a strong conceptual foundation for understanding parts and wholes, which is essential for later work with mathematical fractions, division, and proportional reasoning.
