📚 Mathematics GK Teacher Course Overview | 数学 GK 教师课程概览
The Mathematics GK Teacher Course is designed for educators who want to deepen both their subject knowledge and their classroom practice in mathematics. It combines core mathematical content with pedagogical strategies, assessment literacy, and digital tools so that teachers can explain ideas clearly, anticipate student errors, and build coherent lessons across key mathematical strands.
数学 GK 教师课程旨在帮助教师同时深化数学学科知识与课堂教学实践。课程将核心数学内容、教学策略、评估素养和数字工具相结合，使教师能够清晰地讲解概念、预判学生错误，并围绕关键数学主线设计连贯的课堂。
1. What Is the Mathematics GK Teacher Course? | 什么是数学 GK 教师课程？
The Mathematics GK Teacher Course is a professional learning programme structured around the knowledge that mathematics teachers need in real classrooms. 'GK' here is used in the sense of general professional knowledge: it includes not only pure mathematical content, but also curriculum awareness, lesson sequencing, formative assessment, and the ability to explain why procedures work.
数学 GK 教师课程是一门围绕数学教师在真实课堂中所需要的知识而构建的专业学习课程。这里的 'GK' 取 '通用专业知识' 之意：它不仅包括纯数学内容，还包括课程意识、课堂环节设计、形成性评估，以及解释运算为何成立的能力。
The course is modular and can be taught alongside a school's existing professional development programme. Participants typically complete a diagnostic subject audit, engage with model lessons, design their own tasks, and reflect on classroom evidence such as student work samples and video recordings.
该课程采用模块化设计，可与学校现有的教师发展项目并行实施。参与者通常需要完成学科诊断测评、观摩示范课、设计自己的任务，并根据学生作业样本和课堂录像等证据进行反思。
2. Course Aims and Learning Outcomes | 课程目标与学习成果
By the end of the course, teachers should be able to explain the central concepts of number, algebra, geometry, and statistics at the level they teach, and also at the next level up. This vertical knowledge helps teachers see how current learning connects to future learning and why a topic matters in the wider curriculum.
课程结束时，教师应能讲解所教年级及更高一年级的数、代数、几何和统计核心概念。这种纵向知识有助于教师看清当前学习与未来学习的联系，以及某个主题在更广泛课程中的意义。
In addition, teachers should be able to plan a sequence of lessons with clear learning intentions, success criteria, and hinge questions. They should also be able to interpret assessment data and adjust instruction so that all learners make progress, not just those who already find the material easy.
此外，教师应能围绕清晰的学习目标、成功标准和关键诊断问题设计一系列课程。他们还应能够解读评估数据并调整教学，使所有学生都取得进步，而不仅仅是那些已经觉得内容简单的学生。
3. Core Content Strands: Number, Algebra, Geometry, Statistics | 核心内容主线：数、代数、几何、统计
The content spine of the course follows four strands. In number, teachers revisit place value, fractions, ratio, proportion, and indices. A key question is why 3/7 + 2/5 cannot be found by adding numerators and denominators, and how common denominators preserve equivalent value.
课程的内容主线遵循四个分支。在 '数' 这一分支中，教师重新审视位值、分数、比、比例和指数。关键问题是为什么 3/7 + 2/5 不能通过直接将分子与分母相加来计算，以及通分如何保持等值。
In algebra, the course moves from arithmetic generalisation to symbolic manipulation. Teachers explore how the distributive law underpins expanding brackets, factorising, and solving linear equations.
在代数分支中，课程从算术推广过渡到符号运算。教师探讨分配律如何支撑去括号、因式分解与一次方程求解。
a(b + c) = ab + ac
They also examine common visual models such as area diagrams and balance scales.
他们还会研究面积图与天平模型等常见可视化工具。
Geometry content includes angle facts, congruence, similarity, Pythagoras' theorem, and circle theorems. Teachers analyse why the three angles of a triangle sum to 180°, using both formal proof and classroom demonstration. In statistics, the course covers data representation, averages, spread, and probability, with attention to how sample size affects conclusions.
几何内容包括角的基本事实、全等、相似、勾股定理和圆的性质。教师分析三角形内角和为什么为 180°，既使用严格证明，也借助课堂演示。在统计分支中，课程涵盖数据表示、平均数、离散程度和概率，并关注样本容量如何影响结论。
| Strand | Core topics | Key teacher question |
|---|---|---|
| Number | Fractions, ratio, proportion, indices | Why does a common denominator work? |
| Algebra | Linear equations, brackets, factorising | How does the distributive law connect arithmetic and symbols? |
| Geometry | Angles, congruence, similarity, circle theorems | What is the difference between demonstrating and proving a theorem? |
| Statistics | Averages, spread, probability, sampling | Why can
