The advanced set of acrylic number tiles for the checker board, the decimal checker board, the flat bead frame and the bead material, in grey and white with the numerals printed in black. Black is the point: the ordinary tiles carry the hierarchy colours, and a child reading colour can place a figure without ever thinking about which category it belongs to. Take the colour away and the move from one category to the next has to be understood, which is exactly what these are for. Acrylic and wood, for ages 6 to 12.
“The child is both a hope and a promise for mankind.”
This material embodies Maria Montessori's principle of isolation of difficulty by presenting numbers through contrasting colors and tactile experiences. The gray and white tiles create visual discrimination opportunities while supporting the mathematical mind's development through concrete manipulation.
Following the sensorial-to-abstract progression, children internalize numerical sequences through repeated handling and ordering. The material respects the child's need for repetition and self-correction, as the visual contrast provides immediate feedback. By engaging multiple senses, visual discrimination through color contrast, tactile exploration through tile manipulation, and kinesthetic learning through sorting, this material prepares the mathematical mind while refining sensorial perception. The limited number range (1-8) allows for mastery without overwhelming the child, honoring Montessori's principle of presenting just enough challenge to maintain engagement while ensuring success.


Follow the Montessori method of presentation for optimal child development.
Place the box on a work mat with all tiles mixed inside. Ensure adequate lighting to highlight the color contrast. Work from left to right to establish directionality for later reading and writing.
Remove all tiles and place them randomly on the mat
Begin sorting tiles by color into two distinct groups
Arrange gray tiles in numerical sequence from 1-8
Arrange white tiles in numerical sequence below the gray tiles
Return tiles to box in alternating color pattern

Contrasting colors enhance the child's ability to distinguish and categorize numerical symbols while developing visual perception skills.
Bridges sensorial experiences with abstract mathematical concepts through concrete manipulation of numbered tiles.
Present this material after the child has worked extensively with color tablets and number rods
Everything you need to know about this material.
Contact Our ExpertsThis material develops visual discrimination, numerical sequencing, order, concentration, and mathematical readiness. Children learn to distinguish between contrasting colors while reinforcing number recognition and sequence from 1-8.
Children sort and arrange the numbered tiles by color and numerical sequence. They can create patterns, practice ordering numbers, and engage in various extension activities that bridge sensorial work with mathematical concepts.
The contrasting gray and white colors provide clear visual discrimination without distraction. This neutral color scheme helps children focus on the numerical aspect while still engaging their visual sense, supporting both sensorial and mathematical development.
While designed for ages 6-12, this material is particularly beneficial for children transitioning from sensorial to mathematical work. It's ideal for reinforcing number concepts in lower elementary while providing pattern and sequencing challenges for older children.
Children can create alternating color patterns, practice skip counting, explore odd and even numbers, create mathematical equations, or use the tiles for memory games. The material also supports work with factors and multiples.
