The Psychoarithmetic: Soft Cover is a Educational Materials Montessori material designed for children aged 3-6, crafted by Nienhuis Montessori to AMI standards.
This soft cover edition of Maria Montessori's Psychoarithmetic forms part of the essential Montessori Series (Volume 20), providing foundational insights into the mathematical mind of the child. The book explores Montessori's revolutionary approach to teaching arithmetic through concrete materials and psychological principles, offering educators and parents comprehensive guidance on nurturing mathematical understanding in young children.
“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
Psychoarithmetic reveals Maria Montessori's discovery that children possess an innate mathematical mind, manifesting through their natural tendency to order, classify, and quantify their environment. This soft cover edition illuminates how arithmetic emerges from the child's psychological development rather than from imposed instruction. The book demonstrates why Montessori mathematics begins with concrete manipulatives—the child touches quantity before abstracting to symbols. Psychoarithmetic explains the progression from sensorial exploration to mathematical abstraction, showing how each material builds upon previous experiences. The text details why children aged 3-6 eagerly engage with mathematical concepts when presented through materials that match their developmental needs. This volume guides educators in recognizing the child's sensitive period for order and precision, which naturally extends into mathematical thinking. Psychoarithmetic emphasizes that mathematical understanding develops through the child's own activity with purposefully designed materials, not through memorization or direct teaching.

Each order includes everything needed for proper presentation and long-term use.

Everything you need to know about this material.
Psychoarithmetic explores Montessori's approach to teaching arithmetic through concrete materials, covering the psychological foundations of mathematical learning, the development of the mathematical mind, and practical methods for introducing number concepts, operations, and problem-solving to children ages 3-6.
While Psychoarithmetic provides valuable insights for any adult interested in children's mathematical development, it is primarily written as a professional text for educators. Parents may find it most useful when combined with practical Montessori guides or when they have some familiarity with Montessori principles and materials.
As part of the official Montessori Series, this book presents Maria Montessori's original theories and methods directly from her lectures and writings. It provides the theoretical foundation and psychological understanding behind Montessori math materials, rather than just practical activities or lesson plans.
Although marketed for ages 3-6, Psychoarithmetic actually covers mathematical development from early childhood through elementary years, explaining how foundational concepts introduced to 3-6 year olds prepare them for more advanced mathematical thinking in later years.
While the book references classic Montessori math materials like golden beads, number rods, and spindle boxes, it primarily focuses on understanding the child's mathematical mind and the principles behind the materials. You can adapt many concepts using everyday objects, though authentic Montessori materials are designed to best support the methods described.
