Colorlotl

Color by number, with Gilly the axolotl.

Tap a color, then tap the shapes with that number. Older children can switch to times tables, where every shape shows a problem and the colors are the answers. Finishing pictures brings new axolotls into the tank, each with real facts about its kind.
