小学奥数全套100题
作者:silverlegend
近些年来,小学教辅书有个奇怪的趋势,喜欢在印刷上做文章,搞的花花绿绿的,把低幼绘本那套画风延伸过来。语文英语之类的文科这么折腾也就罢了,数学这么搞,就很让人费解。
出版社的意图,大约是试图营造一种轻松愉快的学习氛围,某种程度上抵消学科本身的枯燥。但是很遗憾,单就数学而言,它本身就没啥乐趣可言,对于厌学的小朋友,这种表面功夫,实属枉然。
不少小学奥数教材也迎合了这种恶趣味,这里点名批评高思课本,喧宾夺主本末倒置,简直辣眼睛,虽然它家的高思导引属于奥数习题集标杆级的存在。
今天晒的这套《奥数精讲与测试》,实属一股清流,朴实无华,内容扎实,别有一番风味。总主编熊斌,是跟单墫单大爷边上边下的大佬,有他坐镇,妥妥没坑。这个系列贯穿小学到高中,畅销十几年,口碑甚好。
扔几个狗东链接……
一套六本,封面板式统一,颜色略有区别……
封皮直接秀出既往限量,底气十足……
封底介绍了两位主编……
扉页……
版权页……
再版前言……
文末有熊大爷的签名……
前言,介绍了本书的定位跟编排体例……
目录……
晒完整一章,感受一下……
开篇介绍知识点跟重难点,人狠话不多,要言不烦……
接着直接进入例题环节。这个修订版与时俱进,部分例题跟习题提供了配套讲解视频,页面侧边有二维码,扫之,即可播放视频……
每章例题不算太多,只是点到为止,对得起“精讲”二字。重头戏在习题部分,根据难度,分为ABC三篇,难度层层递进……
部分习题也配有视频讲解……
书末附有参考答案,很是详尽……
感受一下视频讲解的画风,同样的朴实无华……
这套书单册只有薄薄的两百来页,排版紧凑,内容扎实,毫不注水,是一套优秀的小学奥数教程,整体难度高于单墫大爷主编的小蓝本,可以根据个人喜好进行选择。
就这样吧,感谢围观!
