Fill the fat little pen with water, sweep it across the page, and numbers, counting scenes and hidden pictures spring to life in bright color. As the page dries the color melts away, leaving a clean pad ready to count all over again — no paints, no markers, no mess.

Four thick, laminated pages turn early number learning into a game little hands can't put down, with pictures to find on every pass. Tidy and spill-proof, it's made for tables, car seats and anywhere you need busy, quiet hands.

Slim enough for any bag, it's screen-free math practice that feels like play.
