前言/序言

一直在京东购买书籍，不同时段的折扣，不同力度的折扣都非常吸引人，质量保证，买了好些年没有掺杂盗版书籍，值得信赖。不定时的会挑些书籍收藏，等打折力度大时入手。一年最优惠的两个时段，六月份的购书节还有双十一。想想都乐。还有评价还能得京东豆，这个不能使懒！好东西值得分享与评价，今年又买了一百多本，买书的频率赶不上看书的节奏，但还是停不下来。喜欢纸质的感觉。

一本适合小宝宝算术 几何启蒙的书，个人觉得5岁左右开始可以用。有些平面转换立体的内容，小朋友可能看不太明白，但是，可以帮助建立空间感知力，总之，内容上个人非常满意；运输时间长一些，第三方发货也可以理解。图片上发了一个平面立体转换的照片，家长们可以体会一下。

　　《DK儿童数学思维手册》同时也可以作为教师和家长的教学指导读物。幼儿园的老师和家长可以为儿童们讲解书中较浅显常见的数学常识，为儿童进入小学前接触数学知识做好基础准备；小学和初中的老师和家长可以用本书配合数学课，向儿童进行多角度、多维度的知识教学。

1.通过贴贴纸、涂色、走迷宫等孩子喜欢的游戏让孩子愉快地接触英语单词。另外，将同一个英语单词反复出现在不同的游戏中，使孩子不仅不会产生厌倦，还能自然而然地对英语产生认同感。

DK的书每本都很喜欢，确实不错，让孩子觉得神奇的很，千变万化，虽然与传统的数学学习关系不算太大，但这本书本身就很好看
