Attach the sorter to the bathtub with the suction cups.

Fit the gears according to their shapes and colors. Each gear can be fit only with the matching shape, strengthening your child’s understanding of different shapes.

Fill up water in the test tube numbered with volume marks and pour over the whole machine so the gears spin delightfully.

Show your toddler how to maneuver the large, easy-to-grasp shapes, and then spin the gears – supporting their fine-motor development.
