ABSTRACT:
The educational toy of the present invention comprises a base and transparent tubular members attached to the base arranged in a generally parallel relationship to each other. The output end of each tubular member is lower than the input end of each tubular member so that balls inserted in the input end flow to the output end. Removable means are provided at the output ends for retaining the balls within the tubular members. Insertion and removal of balls from the tubes by the user improves hand-eye coordination. The toy is useful in teaching left/right, up/down, and part-whole relationships. The device teaches movement, counting, and color awareness.
