    • The invention relates to a tri-surface table tennis table and method of use, the tennis table comprising a configuration achieved placing three regulation tennis table surfaces next to each other to form a symmetrical arrangement, so that two of each surface's vertexes touch another surface's vertex, with each two touching vertexes forming a 120° angle. The invention also comprises a triangular surface that fits in the hole created in the center of the tri-surface configuration to form a smooth surface holding the three tennis table surfaces together, and a trilateral net structure further comprising three pieces of net, each piece of net having an inner end and an outer end, wherein the three inner ends are attached to one another and centered on the tri-surface table tennis table and the outer ends are one hundred twenty degrees apart, running to the three touching vertexes of the three playing surfaces.

    • A teaching device assists a child in learning to put on shoes correctly by rewarding the child when the shoes are put on correctly. A telescoping enclosure has a movable upper section with footprints on the upper section. The footprints are shaped to conform to right and left shoes, and additional symbols may be applied to the footprints. The child's shoe will have a shorting bar to cooperate with an electric grid on one of the footprints. As a result, when the shoes are on correctly, the shorting bar will engage the electric grid so a circuit will be completed, and entertainment will be provided in the form of light and/or sound play.
    • 一个教学装置可以帮助孩子学习正确地穿上鞋子,以便在鞋子正确放置时给予孩子奖励。 伸缩式外壳具有可移动的上部,上部具有脚印。 脚印的形状适合于右鞋和左鞋,并且附加符号可以应用于足迹。 孩子的鞋子将有一个短路棒与其中一个脚印上的电网配合。 结果,当鞋子正确地接通时,短路杆将接合电网,从而完成电路,并以光和/或声音的形式提供娱乐。
