01

The Number Grid

Master subitizing and number recognition through tactile exploration. A clean, focused interface for understanding quantity — from counting to pattern recognition.

Clean Math Number Grid
02

The Tens Frame

Build a visual foundation for "base ten" using heavy, snap-to-slot counters. The digital equivalent of physical tokens — with the satisfying weight of real materials.

Clean Math Tens Frame
03

The Bead Chain

Understand length and sequence by dragging strings of colored beads. A classic Montessori material reimagined for glass — with the same deliberate, focused interaction.

Clean Math Bead Chain
04

The Pie Circle

An intuitive introduction to parts and wholes through interactive fractional slices. Children build tactile and visual mastery of fractions — halves, thirds, quarters, and beyond.

05

The Equivalence Scale

Discover the "why" behind addition and subtraction using a responsive balance scale. Mechanical feedback for mathematical logic — making abstract concepts physically tangible.
