1. Course Overview and Aims | 课程概览与目标
Year 8 Advanced Mathematics within the SQA framework builds on the Broad General Education (BGE) phase, targeting the third and fourth curriculum levels. The course covers number processes, algebra, geometry, measurement, statistics, and probability, with an emphasis on problem solving and mathematical reasoning.
在SQA框架下的Year 8进阶数学以广泛普通教育（BGE）阶段为基础，针对第三和第四课程水平。该课程涵盖数的运算、代数、几何、测量、统计与概率，并注重问题解决能力和数学推理。
Students will learn to use mathematical language, interpret real-life situations, and present solutions logically. The syllabus encourages the use of calculators and digital tools appropriately, while also developing mental arithmetic fluency.
学生将学习使用数学语言、解释实际情境并有条理地呈现解题过程。课程大纲鼓励学生恰当使用计算器和数字工具，同时培养心算的熟练度。
2. Number Systems and Operations | 数系与运算
This module deepens understanding of integers, fractions, decimals, and percentages. Students perform operations with negative numbers, convert between equivalent forms, and apply the order of operations (BIDMAS/BODMAS).
本模块深化对整数、分数、小数和百分数的理解。学生将进行负数的运算，在等价形式之间转换，并运用运算顺序（BIDMAS/BODMAS规则）。
Key skills include simplifying fractions, finding percentages of quantities, and calculating percentage increase and decrease. For example, increasing £120 by 15% yields £138.
关键技能包括约分、求一个数量的百分比以及计算百分比的增减。例如，将120英镑增加15%得到138英镑。
udents evaluate squares, cubes, square roots, and cube roots. They understand that 3² = 9, √81 = 9, and 5³ = 125. Negative exponents are explored in simple cases.
课程引入乘方和开方运算：学生将计算平方、立方、平方根和立方根。他们理解 3² = 9，√81 = 9，5³ = 125。在简单情形下还会探索负指数。
Standard form is touched upon for very large and very small numbers, linking to scientific contexts.
对于极大和极小的数字，课程简要涉及标准形式，并与科学背景相联系。
3. Algebraic Expressions and Equations | 代数表达式与方程
ckets, and factorising simple expressions. They learn to multiply a single term over a bracket, e.g., 3(x + 4) = 3x + 12.
Year 8进阶数学中的代数内容已超出简单的代入。学生将通过合并同类项、展开括号和因式分解简单表达式来化简代数式。他们学习单项式乘以括号，如 3(x + 4) = 3x + 12。
ng to x = 4. They also solve simple inequalities and represent solutions on a number line.
解一元一次方程是核心内容。学生将解决未知数在等式两边的方程，例如 5x - 2 = 3x + 6，解得 x = 4。他们还会解简单不等式，并在数轴上表示解集。
a formula, e.g., from F = ma to a = F/m. This skill is essential for science applications.
处理公式：学生将变换公式的主题，例如由 F = ma 变形为 a = F/m。这项技能对科学应用至关重要。
Sequences and the nth term are introduced, enabling learners to generate terms and describe linear patterns algebraically.
数列和第n项的概念被引入，使学生能够生成各项并用代数描述线性模式。
4. Linear Functions and Graphs | 线性函数与图像
Students explore the connection between algebraic equations and their graphical representations. They plot points on a Cartesian plane, draw straight-line graphs, and interpret features such as intercept and gradient.
学生探索代数方程与其图像表示之间的联系。他们在笛卡尔坐标平面上描点、绘制直线图像，并解读截距和斜率等特征。
The equation of a line is given in the form:
y = mx + c
where m is the gradient and c is the y-intercept. Leaners calculate gradient from a graph or from two points using (y₂ - y₁)/(x₂ - x₁).
其中 m 为斜率，c 为y轴截距。学生根据图像或通过 (y₂ - y₁)/(x₂ - x₁) 由两点坐标计算斜率。
Real-life contexts such as distance-time graphs and conversion graphs reinforce understanding. For instance, a distance-time graph with constant speed yields a straight line whose slope represents speed.
距离-时间图和转换图等实际情境可强化理解。例如，匀速运动的距离-时间图是一条直线，其斜率代表速度。
Advanced learners may also graph simple inequalities on the coordinate plane, shading regions such as y > 2x + 1.
学有余力的学生还可以在坐标平面上画出简单不等式的图像，并对 y > 2x + 1 等区域进行着色。
5. Geometry: Angles, Shapes, and Constructions | 几何：角度、形状与作图
Geometry in Year 8 covers properties of angles, triangles, quadrilaterals, and polygons. Students learn about vertically opposite angles, angles on a straight line, and angles around a point. They use these rules to find missing angles in diagrams.
Year 8的几何涵盖角、三角形、四边形和多边形的性质。学生学习对顶角、直线上的角和围绕一点的角。他们运用这些规则求出图形中的未知角度。
The angle sum in a triangle is 180°, and in a quadrilateral is 360°. Interior and exterior angles of regular polygons are calculated. For a regular pentagon, each interior angle is 108°.
三角形的内角和为180°，四边形的内角和为360°。计算正多边形的内角和外角。对于正五边形，每个内角为108°。
Pupils construct triangles and bisect lines and angles using compasses and straightedge. Circle vocabulary — radius
