🎨 How to color it

Color the large 4 in teal and the tall 0 in golden yellow, then make the abacuses cherry red, the rulers sky blue, and the tiny open book lavender. Use sharp colored pencils for the tight chevrons, dots, and ruler marks, saving markers for the big blocky number spaces. Try a repeating classroom pattern by alternating two greens inside the triangle shapes and leaving the small display frames bright white.

Between the ruler racks of Geometry Hall, Dalia slid a square tile across the cool floor and whispered, “One quiet turn.” She had invented Window-Wait, a game where every pause earned one empty frame for the number 40. The hall smelled like pencil shavings and rain on stone. Thirty-nine times, the tile clicked, the abacus beads shivered, and nothing stayed open.

Dalia tucked her knees under her, listening to the soft tick of chalk dust falling from the ceiling lines. A triangle pointer swung. A tiny book rustled its pages. “Wait with me,” she told the silent 40. On the fortieth pause, the zero’s center warmed like morning paper, and four square windows settled into the number’s side.

Ever since, forty keeps windows for patient counters, so a long wait can look back and see every quiet turn it saved.
