之前我们介绍了新加坡政府小学一年级的教学大纲，今天我们接着来看新加坡政府小学二年级的教学大纲。
回顾一下，整个小学阶段，采用3+1的教学体系，三大模块数学知识和贯穿始终的数学过程思维训练。如下图所示。
数学过程思维这一环节最为关键的是思维技巧和策略思维方法。这部分内容是要求学生在掌握数学知识点的基础上，能活学活用，经过训练，学会常用的思维方法。
比如，从特例推导到一般的思维技巧，发现规律，找出通用模式。将整体拆解成部分，用“分而治之”的方法化整为零突破。从部分整合到全局的能力。猜测+验证的方法，对有些不能采用穷举方法的问题也很管用。具体如下图。
新加坡小三的知识点脉络，总结如下图。
每个分支包含的知识点分列如下。
10000以内整数知识考查点
counting in tens/hundreds
number notation, representations and place values (hundreds, tens, ones)
reading and writing numbers in numerals and in words
comparing and ordering numbers
patterns in number sequences
和二年级相比，知识点没有变化，但通过应用题增加深度，培养学生综合分析能力，部分试题实际上已经有数论的味道。
