新加坡政府小学数学大纲及考点（小学二年级G2）

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。

新加坡小二的知识点脉络和小一大体相当，但在难度上会加深一个层级，总结如下图。

每个分支包含的知识点分列如下。
