The Checker Board is a Educational Materials Montessori material designed for children aged 6-12, crafted by Nienhuis Montessori to AMI standards.
The Checker Board is an advanced Montessori mathematics material that enables children to explore multiplication of large numbers through a concrete, visual method. This precision-crafted wooden board features a 6x5 grid of alternating colored squares with powers of ten labeled along the edges, transforming abstract multiplication concepts into tangible, hands-on learning experiences.
“The child is both a hope and a promise for mankind.”— Maria MontessoriEducation and Peace
“The hands are the instruments of man's intelligence.”

The Checker Board transforms multiplication of large numbers into a concrete visual experience through its distinctive 6x5 grid of alternating colored squares. Each square on this precision-crafted wooden board represents a specific power of ten, allowing children to physically place number tiles and witness how digits interact across place values during multiplication. The alternating colors of the Checker Board create a visual pattern that helps children track diagonal movements when carrying numbers, making the abstract process of regrouping tangible and comprehensible. This mathematical tool bridges the gap between concrete manipulation and abstract calculation by providing a spatial representation where children can see, touch, and move quantities while discovering multiplication patterns. The board's labeled edges showing powers of ten serve as constant reference points, enabling children to maintain orientation while working with numbers reaching into the millions.
Each order includes everything needed for proper presentation and long-term use.
Follow the Montessori method of presentation for optimal child development.
Write the multiplicand across the top edge and multiplier down the right side
Begin with the units digit of the multiplier, placing corresponding tiles on each square horizontally
Continue with tens, hundreds, etc., moving down one row for each digit of the multiplier
Count tiles diagonally, starting from bottom right, exchanging 10 tiles for 1 of the next place value
Record the final answer by reading the remaining tiles from left to right
Every material is carefully selected for durability, safety, and authentic Montessori experience.
The sturdy wooden frame provides a stable work surface that withstands years of classroom use while offering the natural warmth and texture children connect with.
Carefully selected fabric or felt squares create distinct visual and tactile boundaries between place values, helping children organize their work methodically.
Each material supports multiple areas of child development simultaneously.
Bridges concrete manipulation to abstract mathematical thinking through systematic exploration of multiplication patterns.
Reinforces understanding of powers of ten and their relationships in large number operations.
Complex multi-step problems build sustained focus and methodical work habits.
Success with large numbers builds self-assurance in tackling advanced mathematical concepts.
Designed for child-sized hands
Professional tips from AMI-trained guides to maximize the educational value of this material.
“Introduce the Checker Board only after mastery of the Stamp Game multiplication to ensure readiness”
Demonstrate the diagonal counting pattern using a pointer or thin stick for visual clarity
Create a multiplication problem gallery where children can select increasingly challenging problems
Use the board's color pattern to explain why we move diagonally when carrying in multiplication
Everything you need to know about this material.
The Checker Board teaches multiplication of large numbers, place value understanding, and the distributive property of multiplication. Children learn to multiply multi-digit numbers by breaking them down into units, tens, hundreds, and thousands, making abstract concepts concrete through visual and tactile manipulation.
Unlike paper-and-pencil methods, the Checker Board provides a visual, hands-on approach where children physically place beads on colored squares representing different place values. This concrete method helps children understand why multiplication algorithms work rather than just memorizing procedures.
The Checker Board includes a precision-crafted wooden board with a 6x5 grid of alternating colored squares, numbered along the edges with powers of ten. Additional materials needed but often sold separately include colored bead bars and number cards for complete multiplication exercises.
Children should be comfortable with basic multiplication facts, understand place value concepts, and have experience with other Montessori multiplication materials like the Multiplication Bead Board or Golden Beads. Typically, children are ready for this material around age 7-8.
The Checker Board builds a strong foundation for algebra by demonstrating the distributive property visually. It prepares children for polynomial multiplication, develops logical thinking skills, and creates a deep understanding of how numbers interact in multiplication, supporting future abstract mathematical thinking.
