新加坡政府小学数学大纲及考点小学三年级

之前我们先容了新加坡当局小学一年级的教授教养年夜纲，本日我们接着来看新加坡当局小学二年级的教授教养年夜纲。

回想一下，整个小学阶段，采纳3+1的教授教养系统，三年夜模块数学常识和贯串始终的数学进程思维训练。如下图所示。

数学进程思维这一环节最为症结的是思维技能和策略思维办法。这部门内容是要肄业生在掌握数学常识点的根基上，能活学活用，颠末训练，学会常用的思维办法。

好比，从特例推导到一样平常的思维技能，发现纪律，找出通用模式。将整体拆解成部门，用“分而治之”的办法化整为零突破。从部门整合到全局的才能。预测+验证的办法，对有些不克不及采纳穷举办法的问题也很管用。详细如下图。

新加坡小三的常识点脉络，总结如下图。

每个分支包括的常识点排列如下。

10000以内整数常识考查点

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，常识点没有变化，但经由过程利用题增长深度，造就学生综合阐发才能，部门试题现实上已经稀有论的味道。
