小家伙做一个关于面积的数学题,面积是他新学期要学的内容,妈妈讲讲他就表示明白了,于是开始做题。 ![image.png](https://cdn.steemitimages.com/DQmW6u76qNSsh1fDNfTqAhjbBUfYkK8W8zrDomA8RVYS4zf/image.png) (Image source: [https://pixabay.com/](https://pixabay.com/)) 前几道题小家伙做得还算顺利,这道题确是有点绕弯,是在一个正方形的四条边上每条边上都取中心点,然后由四个中心点组成个新的正方形,求新的正方形面积。 我们学过的再回头看,都会觉得挺简单,把小正方形分成四个三角形,然后挪一下,就变成了一个长方形,正好是原来正方形面积的一半。 可是小家伙思索来思索去,他总是想计算出新的正方形边长,然后按着边长*边长的方式计算(这是他学习到的正常的算法),可是这样或许会算出来,但是不是他掌握的知识所以搞定的啦。 小家伙算了一会后果断放弃,让妈妈给他讲解一下该如何取做,妈妈让他自己再多思考一会。 可是小家伙突然来了一句: >吾尝终日而思矣,不如须臾之所学也。 然后和妈妈说,我自己想大半天也不如你给我简单讲讲见效快。妈妈一下子被弄懵了,觉得好像不对,又不知道哪里不对,哈哈哈哈。 ![image.png](https://cdn.steemitimages.com/DQmd9N5d2M4CXZeWUXEEJh2bgGedaEuQPPoUbghZAAAwDZy/image.png) (Image source: [https://pixabay.com/](https://pixabay.com/)) 最终妈妈给小家伙一个提示,让他把正方形拆拆看,小家伙自己就想出方法和答案啦。
