Jean Piaget was a Swiss developmental psychologist and philosopher known for
his epistemological studies with children.
It is very hard to read and grasp author's idea,But still it is very good
book to understand children's psyche about numbers.
Book summary based on my poor understanding:
Stage of understanding number:
Stage 1: intuition, perceptual, no understanding of number concept (

Kids may be ready for math earlier than you think

摘要：研究发现，3岁的幼儿就可以理解数字的含义。
这个报告发现了一个重要的情况：儿童认数字比用实物的教具更有效。
这个和我的教育理念基本一致——
人大脑本身在小数目是可以实例化的，而大的数目要用抽象的方式对待。
美国数学教育界过于强调用“实例”教育，损伤了孩子的数学抽象能力。
Children as young as 3 can understand the meaning and value of multi-digit
numbers and might be more ready for direct math instruction when they begin

读书，看电影都应该是个非常愉悦的事情
在孩子小的时候，在孩子还在 grasp reading skills的时候
我崇尚让孩子读他们自己喜欢的书，多读书，粗读
为的就是慢慢培养孩子对阅读的热爱，让阅读变成一种习惯
其他的精读，阅读理解，分析归纳总结甚至写作，都可以等
初中，在孩子有了良好的阅读习惯之后，再整都来得及
所以呢，嫩想娃读书之后跟娃3言2语的讨论交流一下，ok
不要太有目的太有“功利”心了
孩子不ready的时候整这些，很可能会伤害孩子求知阅读之心地
尤其是如果父母不知道如何温和有效地“推“
让嫩跟娃之间的交流变成一种享受，而不是摸底考试judgemental call |
