图卡表是一种制作简易、使用方便、一次制作可反复使用的“土”教具。任何学校都有条件制作和使用。 1.制作:取长方形纤维板一块,在靠近一边处取对称两点,钻孔并系绳,以便悬挂。正面涂成黑色,用白线分成纵横各数格。在每空格靠近上缘的正中,从反面钉一枚鞋钉,即成图卡板。取略小于表中空格的长方形纤维板数块(与空格数相等),古面涂黑,要便于书写和擦掉,在靠近上边的正中钻孔,以便挂在表中鞋钉上,即成
The map card table is a kind of “earth” teaching aid that is simple to make, easy to use, and can be used repeatedly at one time. Any school has conditions to make and use. 1. Production: take a piece of rectangular fiber board, take two symmetrical points near one side, drill and tie rope to hang. The front is painted black and divided into white and vertical lines with white lines. In the middle of each space close to the upper edge, a spike is nailed from the opposite side, which is a map card board. Take rectangular fiberboard blocks (equal to the number of spaces) that are slightly smaller than the spaces in the table. The old ones are painted black. To facilitate writing and erasing, drill holes in the middle near the top so that they can be hung on the spikes in the table.
