学习数学,特别是几何,离不开空间想象能力。空间想象能力要通过实践的积累和训练来提高,初学者常可通过动手画画、剪剪、贴贴等实践活动来弥补空间想象能力之不足。当然,在动手的同时还应多动脑,先想象可能出现的各种结果,再通过实践活动去验证,逐步形成较强的空间想象能力。怎样训练空间想象能力呢?请看一例: Learning mathematics, especially geometry, is inseparable from spatial imagination. The space imagination ability should be improved through the accumulation and training of practice. Beginners can often make up for the insufficiency of space imagination ability through hands-on drawing, shearing, sticking and other practical activities. Of course, we should also use our brains at the same time as we begin. Imagine the various possible outcomes and then verify through practical activities to gradually form a strong spatial imagination. How to train spatial imagination? See an example:
