1. Number and the Number System | 数字与数系
The number system unit in Year 7 WJEC Further Mathematics extends well beyond basic arithmetic. Students work with integers, decimals, and directed numbers across all four operations, but the emphasis shifts toward place-value reasoning, order of operations with nested brackets, and the confident manipulation of very large and very small numbers using index notation and standard form. Prime factorisation is taught not merely as a standalone skill but as a tool for finding highest common factors (HCF) and lowest common multiples (LCM) efficiently in worded problems. Students also explore squares, cubes, square roots and cube roots, linking these to geometric representations of area and volume.
Year 7 WJEC 进阶数学的数字单元远不止基础算术。学生需要熟练运用整数、小数和带符号数进行四则运算，但重点转向位值推理、含嵌套括号的运算顺序，以及使用指数记数法和标准形式自信地处理极大和极小的数字。质因数分解不仅作为独立技能教授，更被当作在文字题中高效寻找最大公因数（HCF）和最小公倍数（LCM）的工具。学生还将探索平方数、立方数、平方根和立方根，并将其与面积和体积的几何表示联系起来。
- Place value up to billions and down to thousandths; multiplying and dividing by powers of 10 / 位值涵盖十亿到千分之一；乘以和除以10的幂

- Directed numbers: addition, subtraction, multiplication and division with negative integers and decimals / 带符号数：负整数和小数的加减乘除
2. Fractions, Decimals and Percentages | 分数、小数和百分比
Fluency across fractions, decimals and percentages is a non-negotiable foundation in WJEC Further Mathematics. Year 7 students are expected to convert between all three forms with speed and accuracy, including recurring decimals in simple cases. Operations with fractions extend to mixed numbers and improper fractions, with a strong emphasis on selecting the most efficient method — whether that means finding a common denominator, cross-multiplying, or converting to decimals. Percentage calculations move beyond simple 'find 10%' tasks into percentage increase and decrease, reverse percentages, and expressing one quantity as a percentage of another in multi-step problems.
分数、小数和百分比之间的流畅转换是 WJEC 进阶数学中不可妥协的基础。Year 7 学生需要快速准确地在三种形式之间进行转换，包括简单情况下的循环小数。分数的运算扩展到带分数和假分数，重点强调选择最高效的方法——无论是找公分母、交叉相乘还是转换为小数。百分比计算从简单的"求10%"任务推进到百分比增减、逆向百分比，以及在多步骤问题中将一个量表示为另一个量的百分比。
- Equivalent fractions, simplifying fractions to lowest terms / 等值分数，将分数约分至最简形式
- Adding, subtracting, multiplying and dividing fractions including mixed numbers / 分数的加减乘除，包括带分数

- Expressing one quantity as a fraction or percentage of another in context / 在情境中将一个量表示为另一个量的分数或百分比
3. Introduction to Algebra | 代数基础
Algebraic thinking is at the heart of WJEC Further Mathematics at Year 7. Students learn to use letters to represent variables and unknowns, forming algebraic expressions from worded descriptions and geometric patterns. Simplifying expressions by collecting like terms is practised extensively, including terms with powers (e.g. x² and x³ are recognised as unlike terms). The distributive law is applied to expand single brackets, and the reverse process — factorising by extracting a common factor — is introduced early. Substitution of positive and negative integers into expressions and formulae builds the groundwork for function-based thinking later in the year.
代数思维是 Year 7 WJEC 进阶数学的核心。学生学习用字母表示变量和未知数，根据文字描述和几何模式构建代数表达式。通过合并同类项来化简表达式得到大量练习，包括含幂的项（如认识到 x² 和 x³ 是不同类项）。分配律被应用于展开单项括号，而其逆过程——提取公因式进行因式分解——也早早引入。将正整数和负整数代入表达式和公式，为学年后期基于函数的思维奠定基础。
- Using letter symbols to represent unknowns and variables / 使用字母符号表示未知数和变量
- Writing algebraic expressions from word problems and patterns / 根据文字题和模式写出代数表达式
- Simplifying expressions by collecting like terms, including terms with powers / 通过合并同类项化简表达式，包括含幂的项

- Factorising expressions by identifying and extracting the highest common factor / 通过识别并提取最大公因式进行因式分解
- Substituting positive and negative values into expressions and simple formulae / 将正负值代入表达式和简单公式
4. Linear Equations and Inequalities | 线性方程与不等式
Solving equations in Year 7 WJEC Further Mathematics goes beyond one-step processes. Students tackle two-step and multi-step linear equations requiring careful use of inverse operations and balancing methods. Equations involving brackets demand expansion before solving, and those with the unknown on both sides stretch students to think strategically about which terms to collect first. Inequalities are introduced alongside equations, with students learning to represent solution sets on number lines using open and closed circles. The crucial rule about reversing the inequality sign when multiplying or dividing by a negative number is taught explicitly and practised repeatedly.
Year 7 WJEC 进阶数学中的方程求解超越了一步过程。学生需要处理两步和多步骤线性方程，要求仔细运用逆运算和平衡法。含括号的方程需要先展开再求解，而未知数出现在等号两边的方程则促使学生策略性地思考先合并哪些项。不等式与方程一同引入，学生学会使用空心圆和实心圆在数轴上表示解集。当乘以或除以负数时需要反转不等号这一关键规则被明确教授并反复练习。
- Solving one-step equations using inverse operations fluently / 熟练使用逆运算求解一步方程
- Solving two-step and multi-step equations with the unknown on one side / 求解未知数在一边的两步和多步方程

5. Geometry: Angles and Properties of Shapes | 几何：角度与图形性质
The geometry strand in WJEC Year 7 Further Mathematics combines precise vocabulary with deductive reasoning. Students learn to measure and draw angles accurately using a protractor, but the deeper focus is on angle facts and their logical application. Vertically opposite angles, angles on a straight line, angles around a point, and angles in triangles and quadrilaterals are treated as a connected system of rules. Students solve multi-step angle problems that require combining several facts, and they begin to write short justifications for their reasoning — an early form of geometric proof. Properties of triangles (scalene, isosceles, equilateral, right-angled) and quadrilaterals (square, rectangle, parallelogram, rhombus, trapezium, kite) are studied in detail, including symmetry and diagonal properties.
WJEC Year 7 进阶数学的几何板块将精确的术语与演绎推理相结合。学生学习使用量角器准确测量和绘制角度，但更深层的重点在于角度事实及其逻辑应用。对顶角、直线上的角、围绕一点的角，以及三角形和四边形中的角被视作一个相互关联的规则系统。学生需要解决需要综合多个事实的多步骤角度问题，并开始为他们的推理撰写简短的理由说明——这是几何证明的早期形式。三角形（不等边、等腰、等边、直角）和四边形（正方形、长方形、平行四边形、菱形、梯形、筝形）的性质被详细研究，包括对称性和对角线性质。
- Measuring and drawing angles with a protractor to nearest degree / 使用量角器测量和绘制角度（精确到度）

- Line symmetry and rotational symmetry of 2D shapes / 二维图形的线对称和旋转对称
6. Perimeter, Area and Volume | 周长、面积与体积
Measurement in Year 7 WJEC Further Mathematics requires students to move confidently between concrete calculations and abstract formula manipulation. Perimeter of rectilinear and compound shapes is calculated, and students learn to find missing side lengths by reasoning backwards from a given perimeter. Area formulas for rectangles, triangles, parallelograms and trapeziums are derived, memorised and applied, including in problems where students must choose the correct perpendicular height. Compound area problems — shapes made from rectangles and triangles — are tackled systematically. The volume of cuboids is introduced, and students explore the connection between area of the cross-section and volume for prisms. Unit conversions within the metric system are embedded throughout.
Year 7 WJEC 进阶数学的测量部分要求学生自信地在具体计算和抽象公式操作之间切换。学生需要计算直线边图形和复合图形的周长，并学会根据给定的周长反向推理出缺失的边长。长方形、三角形、平行四边形和梯形的面积公式被推导、记忆和应用，包括在必须选择正确垂直高度的问题中。复合面积问题——由长方形和三角形组成的图形——被系统地解决。长方体的体积被引入，学生探索棱柱横截面积与体积之间的联系。整个过程中贯穿公制单位换算。
- Perimeter of rectilinear shapes, compound shapes, and finding missing lengths / 直线边图形和复合图形的周长，以及求缺失边长

7. Coordinates and Graphs | 坐标与图形
ts with positive and negative coordinates and solve geometric problems on coordinate grids — nd parallelograms. The unit introduces the concept of a linear relationship, with students generating tables of values, plotting straight-line graphs, and beginning to recognise the roles of gradient and y-intercept in equations of the form y = mx + c. This visual and algebraic bridge prepares students for the more formal study of linear functions.
在坐标平面的全部四个象限中工作是 WJEC Year 7 进阶数学的一项关键要求。学生绘制具有正负坐标的点，并在坐标网格上解决几何问题——求线段的中点、计算水平和垂直距离，以及识别正方形和平行四边形等图形的缺失顶点。本单元引入线性关系的概念，学生需要生成数值表、绘制直线图形，并开始认识 y = mx + c 形式方程中斜率和y轴截距的作用。这座视觉与代数之间的桥梁为学生后续正式学习线性函数做好准备。

8. Ratio and Proportion | 比率与比例
Ratio and proportion in WJEC Further Mathematics moves rapidly from simple sharing into more nuanced applications. Students simplify ratios — including three-part ratios — and express ratios in the form 1 : n or n : 1. Dividing quantities into a given ratio is practised with both discrete amounts (money, counters) and continuous measures (length, mass). The unitary method is taught as a powerful tool for solving proportion problems, and students learn to distinguish between direct proportion scenarios and non-proportional relationships. Scale drawings and map scales provide a visual context, linking ratio to the geometry and measurement strands. Best-buy and value-for-money problems introduce the practical application of ratio in consumer contexts.
WJEC 进阶数学中的比率与比例从简单的分配迅速推进到更细致的应用。学生需要化简比率——包括三部分比率——并以 1 : n 或 n : 1 的形式表示比率。将量按给定比率分配在离散量（金钱、计数器）和连续量（长度、质量）中都得到练习。单位法被教授为解决比例问题的强大工具，学生学会区分正比例情景和非比例关系。比例尺图和地图比例尺提供了视觉情境，将比率与几何和测量板块联系起来。最佳购买和性价比问题引入了比率在消费情境中的实际应用。

9. Statistics: Collecting, Representing and Interpreting Data | 统计：数据的收集、呈现与解读
The statistics unit in Year 7 WJEC Further Mathematics emphasises the full data-handling cycle: posing questions, collecting data, organising it, representing it graphically, and interpreting the results. Students design data collection sheets and consider issues of bias and sample size. Graphical representations include bar charts, dual bar charts, pictograms, and pie charts — with pie charts requiring students to calculate sector angles from frequencies. Averages are covered in depth: the mean, median, mode and range are all calculated from raw data and from frequency tables, and students learn to choose the most appropriate average for a given context. Comparing two data sets using averages and range develops analytical writing skills.
Year 7 WJEC 进阶数学的统计单元强调完整的数据处理循环：提出问题、收集数据、整理数据、以图形呈现数据以及解读结果。学生设计数据收集表并考虑偏差和样本量的问题。图形表示包括条形图、双条形图、象形图和饼图——饼图要求学生根据频数计算扇形角度。平均数被深入覆盖：平均数、中位数、众数和极差都从原始数据和频数表中计算得出，学生学会根据给定情境选择最合适的平均数。使用平均数和极差比较两组数据培养了分析性写作能力。

10. Probability | 概率
Probability in WJEC Year 7 Further Mathematics is taught through both theoretical and experimental lenses. Students use the probability scale from 0 (impossible) to 1 (certain), expressing probabilities as fractions, decimals and percentages. Sample space diagrams are introduced for systematically listing outcomes of combined events — for example, rolling two dice or flipping two coins. Students calculate theoretical probabilities from equally likely outcomes and compare these with results from simple experiments, developing an understanding of relative frequency and the concept that experimental results converge toward theoretical probabilities with more trials. Mutually exclusive events and the idea that probabilities sum to 1 are formalised.
WJEC Year 7 进阶数学中的概率通过理论和实验两种视角进行教授。学生使用从0（不可能）到1（确定）的概率尺度，将概率表示为分数、小数和百分比。样本空间图被引入，用于系统地列出组合事件的结果——例如，掷两个骰子或抛两枚硬币。学生从等可能结果计算理论概率，并将其与简单实验的结果进行比较，从而理解相对频率的概念以及随着试验次数增加实验结果趋近于理论概率的思想。互斥事件以及概率之和为1的概念被正式化。

- Understanding that the sum of probabilities of all mutually exclusive outcomes is 1 / 理解所有互斥结果的概率之和为1
11. Sequences and Patterns | 序列与规律
Sequences work in WJEC Further Mathematics develops algebraic thinking through pattern recognition and generalisation. Students generate sequences from term-to-term rules expressed in words and, increasingly, in algebraic form. Arithmetic sequences (those with a constant difference) are explored in depth: students find the next terms, identify missing terms, and begin to derive the position-to-term rule (nth term) for simple linear sequences. Patterns presented as diagrams — matchstick patterns, dot patterns, tile arrangements — are used to link visual reasoning directly to algebraic expressions. This unit is particularly important for building the kind of abstract thinking required in later algebra topics.
WJEC 进阶数学中的序列学习通过模式识别和概括来培养代数思维。学生根据用文字表述的项间规则生成序列，并逐渐过渡到代数形式的规则。等差数列（具有恒定差值的序列）被深入探讨：学生求后续项、识别缺失项，并开始推导简单线性序列的位置到项规则（第n项）。以图形呈现的模式——火柴棍模式、点阵模式、瓷砖排列——被用来将视觉推理直接与代数表达式联系起来。本单元对于培养后续代数主题所需的抽象思维尤为重要。
- Generating sequences from term-to-term rules given in words / 根据文字给出的项间规则生成序列

- Using the nth term to find any term in a sequence, including beyond those listed / 使用第n项求序列中的任意项，包括超出已列出范围的项
12. Problem Solving and Mathematical Reasoning | 问题解决与数学推理
WJEC Further Mathematics places problem solving at the centre of the curriculum, not as a separate topic but as a thread woven through every unit. Students encounter multi-step word problems that require them to identify the relevant mathematics from a real-world scenario, break the problem into manageable steps, and communicate their reasoning clearly. They are taught specific strategies: drawing diagrams, making tables, looking for patterns, working backwards, and solving simpler related problems first. Justification and explanation are valued as highly as correct answers — students learn to use mathematical vocabulary precisely and to construct simple logical arguments. This emphasis on reasoning prepares students for the more formal proof expectations in later years.
WJEC 进阶数学将问题解决置于课程的核心位置，不是作为一个独立的主题，而是作为贯穿每个单元的一条主线。学生遇到多步骤文字题，需要从现实场景中识别相关的数学知识，将问题分解为可管理的步骤，并清晰地表达他们的推理过程。他们被教授具体的策略：绘制图表、制作表格、寻找模式、逆向工作，以及先解决更简单的相关问题。论证和解释与正确答案同样受到重视——学生学会精确使用数学词汇并构建简单的逻辑论证。这种对推理的强调为后续学年中更正式的证明要求做好了准备。
- Breaking multi-step problems into smaller, manageable parts / 将多步骤问题分解为较小、可管理的部分
- Choosing the appropriate mathematical method for a given context / 根据给定情境选择合适的数学方法
