A tactile learning aid shaped as a polyhedron with multiple rotating number rings around its body. Each ring can be turned independently to show digits, allowing for visual demonstration and practice of two-digit arithmetic operations—addition, subtraction, multiplication, and division by a single digit. This geometric form makes abstract math concepts both visible and interactive.

The design works as both an educational tool and a playful object, inviting hands-on engagement while reinforcing numerical understanding. Its clear structure turns simple operations into a dynamic experience suitable for learners, educators, and curious makers alike.

Usage Tips

• Assembly: Assemble the rings one by one, then tighten both ends to secure them in place.
• Demonstration: Rotate the rings to set numbers and use the visible combination to explore basic arithmetic.
• Display: Works well on desks, classroom shelves, or study spaces as a moving visual aid.
