My 4-year-old absolutely loves these flashcards! The illustrations are beautiful and the dual-side learning is brilliant. Quality is genuinely premium — much better than what we've seen elsewhere. Highly recommend to parents.

Product information
Graded wooden strips that assemble into the 10x10 Deccanomial Square, Montessori's beautiful bridge between sensorial size work for a preschooler and abstract algebra for a 10-year-old. Same box, ten years of use. The strips arrange into the geometric expansion of (a+b+c+...+j)^2 = 55^2 = 3025 square units. Handcrafted in India in a lacquered beechwood box.

How it compares to an algebra worksheet

| Reuse | Multi-year work cycle | One-off practice |
| Retention | Touch + sight + name | Sight only |
Why curated by SkilloToys
The Deccanomial Squares are one of Montessori's most quietly ambitious materials: a set that a 3-year-old plays with as sensorial pattern work and a 10-year-old unpacks as algebra. Kidken's Indian-made version in a beechwood box is our recommendation when a family wants a single piece of maths material that grows with the child through primary school.
Sensorial size, shape and colour discrimination for young children; concrete introduction to squaring, algebraic expansion of (a+b+c...)^2, area calculation, and the visual link between algebra and geometry for older children.
