1. Number Fundamentals | 数与运算基础
Year 10 reinforces arithmetic with integers, decimals, fractions and percentages. Higher-tier students also work with surds are irrational roots such as √2, and exact values involving π. All students must be accurate with order of operations (BIDMAS/BODMAS) and comfortable converting between fractions, decimals and percentages, including recurring decimals.

Prime factorisation and the use of Highest Common Factor (HCF) and Lowest Common Multiple (LCM) are essential, especially for simplifying fractions and solving real-world problems. Students learn to write numbers in standard form A × 10ⁿ and to calculate with them, which is tested on both tiers.
质因数分解以及最大公因数（HCF）和最小公倍数（LCM）的应用至关重要，特别是在化简分数和解决实际问题时。学生要学习把数字写成标准形式 A × 10ⁿ 并进行计算，这同样是两个级别都会考查的内容。
2. Algebra: Expressions, Equations & Inequalities | 代数：表达式、方程与不等式
Algebraic manipulation is at the heart of Year 10. Students extend simplifying, expanding brackets (including double brackets and triple brackets for Higher), and factorising. The difference of two squares and completing the square (Higher) are key techniques. Linear equations and inequalities are solved, with answers expressed on number lines.
代数操作是 Year 10 的核心。学生要提升化简、展开括号（Foundation 为单项式乘多项式，Higher 包括二次和三次展开）以及因式分解的能力。平方差公式和配方法（Higher）是关键技巧。学生需要求解线性方程和不等式，并在数轴上表示解集。

复合测量如速度、密度和压强将比与单位换算联系起来。学生要学习计算百分比变化、单利和复利，以及增长/衰减问题，通常使用乘数。这些话题与实际生活中的财务问题紧密相关。
5. Geometry: Angles, Polygons & Parallel Lines | 几何：角、多边形与平行线
Angle rules on a straight line, around a point, vertically opposite angles, and in triangles are revisited and extended to parallel lines (alternate, corresponding and co-interior angles). Students apply these to prove geometric properties and solve multi-step problems.
重温并延伸直线上的角、点周围的角、对顶角以及三角形内角的规则，并扩展到平行线（内错角、同位角和同旁内角）。学生要应用这些规则证明几何性质并解决多步问题。
Interior and exterior angles of polygons are derived and used to find missing angles. Regular polygon properties, including symmetry, are examined. Bearings, often combined with scale drawing, require careful angle measurement and calculation.

Year 10 涵盖数据收集、抽样方法（包括分层抽样）和问卷设计。学生要构建并解读多种图表：条形图、饼图、频数多边形、直方图（Higher 包括不等组距）和累积频数图。
Measures of central tendency – mean, median, mode – and measures of spread – range, quartiles and interquartile range – are calculated from lists, tables and grouped data. Box plots provide a graphical summary, and students compare distributions using these statistics.
集中趋势的度量——平均数、中位数、众数——和离散程度的度量——极差、四分位数和四分位距——从列表、表格和分组数据中计算得出。箱线图提供图形化摘要，学生使用这些统计量比较分布。
Scatter graphs are used to investigate correlation and, where appropriate, to draw lines of best fit and make predictions. Understanding the difference between correlation and causation is emphasised.
散点图用于考察相关性，并在合适时绘制最佳拟合线进行预测。重点强调理解相关性与因果关系的区别。
10. Problem Solving, Proof & Exam Skills | 问题解决、证明与考试技巧
Throughout the course, students are expected to apply mathematics in multi-step and unfamiliar contexts. Problem solving requires breaking down complex tasks, selecting appropriate strategies, and communicating reasoning clearly. Mathematical proof, such as algebraic proof and geometric reasoning, is assessed especially on Higher tier.
在整个课程中，学生需要将数学应用在多步和不熟悉的情境中。问题解决要求分解复杂任务、选择合适的策略并清晰地传达推理过程。数学证明，如代数证明和几何推理，在Higher级别尤其会被考察。
Effective exam technique includes reading questions carefully, showing full working, and checking answers for reasonableness. Time management, knowing when to move on, and practicing under timed conditions are crucial. Using the official Edexcel formula sheet wisely and memorising required formulas builds confidence.
有效的考试技巧包括仔细读题、展示完整过程并检查答案的合理性。时间管理、知道何时暂时跳过题目以及在限时条件下练习都至关重要。合理使用 Edexcel 官方公式表并熟记所需公式能建立信心。
