📚 Mathematics G3 Teacher Edition: Course Overview | 数学 G3 教师版课程概览

This teacher edition provides a concise yet comprehensive overview of the G3 mathematics curriculum. It is designed to help teachers map key concepts, plan staged lessons, and align assessment with learning outcomes. The overview covers number, geometry, measurement, data handling, and problem solving, while emphasising how to build conceptual understanding before fluency.

本教师版为 G3 数学课程提供简明而全面的概览。它旨在帮助教师梳理核心概念、规划分阶段教学，并将评估与学习目标对齐。概览涵盖数、几何、测量、数据处理和问题解决，同时强调在计算流畅性之前先建立概念理解。

1. Course Aims and Vision | 课程目标与愿景

The central aim of G3 mathematics is to develop confident learners who can use numbers, shapes, and data in familiar and unfamiliar contexts. Rather than memorising rules in isolation, students are guided to explain their thinking and connect ideas across topics. The teacher edition therefore frames every unit around three questions: what should students know, what should they be able to do, and how do we know they have learned it?

G3 数学的核心目标是培养自信的学习者，使学生能够在熟悉和不熟悉的情境中运用数、图形和数据。学生不是孤立记忆规则，而是被引导解释自己的思维，并将不同主题的知识建立联系。因此，教师版将每个单元围绕三个问题展开：学生应知道什么、学生应能做什么，以及我们如何知道他们已经学会。

The vision also supports vertical alignment: concepts introduced in G2 are consolidated, while foundations for G4 are introduced lightly. Teachers are encouraged to prioritise ‘depth over coverage’ by spending more time on number structure and visual representation before moving to symbols.

该愿景同时支持纵向衔接：G2 引入的概念得到巩固，而 G4 的基础以较轻的力度先行铺垫。教师应优先追求 “深度而非广度”，在进入符号运算之前，花更多时间在数结构和视觉表征上。

2. Core Strands and Content Map | 核心领域与内容地图

The G3 course is organised into five strands: Number, Geometry, Measurement, Data Handling, and Problem Solving. Number typically occupies the largest share of teaching time, followed by measurement and geometry. The content map shows not only topic titles but also prerequisite knowledge and expected exit points.

G3 课程分为五个领域：数、几何、测量、数据处理和问题解决。数通常占据最大的教学时间比例，其次是测量和几何。内容地图不仅显示主题名称，还显示前置知识和预期达到的出口水平。
