课堂会结合心算、笔算和探究式任务，目标是帮助你成为一个自信灵活的思考者，能够清晰解释想法并解决陌生的问题。
2. Transitioning from Primary: What Changes? | 从小学过渡：有什么不同？
In primary school, maths often focuses on getting the right answer quickly. In Year 7, the emphasis shifts towards understanding why a method works and being able to justify your steps. You will be expected to use correct mathematical vocabulary and write down your reasoning in a clear, logical way.
在小学，数学往往注重快速得出正确答案。到了 Year 7，重点转向理解方法背后的原理，并能解释每一步的理由。你需要使用规范的数学语言，并以清晰、有逻辑的方式写下推理过程。
You will also meet a wider range of topics, such as algebra and more formal geometry, which may feel abstract at first. However, teachers will link new ideas to things you already know, so try to see mistakes as a natural part of the learning journey.
你还会接触到更广泛的内容，比如代数和更正式的几何，一开始可能觉得抽象。但老师会把新知识和已知内容联系起来，所以请把错误看作学习过程中的正常部分。
Another change is the pace and structure of lessons. You may now have different teachers for maths, and homework will become more regular. Getting organised with a planner and practising little and often will help you settle in.
另一个变化是课堂节奏和结构。数学课可能由不同老师教授，作业也会更规律。提前用计划手册安排好时间，经常少量练习，能帮你更快适应。
3. Number Skills: Place Value and Operations | 数字技能：位值和运算
A secure understanding of place value is the foundation for all future number work. In Year 7 you will work with whole numbers up to millions and decimals to three decimal places. Reading, writing, ordering and comparing numbers confidently is essential before moving on to calculations.
扎实的位值理解是所有后续计算的基础。Year 7 会处理高达百万的整数以及三位小数。在进行运算前，必须先能自信地读、写、排序和比较这些数字。
The four operations – addition, subtraction, multiplication and division – are extended to larger numbers and to decimals. You will practise efficient written methods such as column addition, short and long multiplication, and short and long division. Mental strategies remain important, especially for estimating answers.
四则运算（加、减、乘、除）会延伸到更大的数字和小数。你会练习高效的笔算方法，如列竖式加法、短乘法和长乘法、短除法和长除法。心算策略仍然重要，特别是在估算答案时。
Negative numbers are also introduced in context, such as temperature or bank balances, and you will learn to order, add and subtract them using a number line. The key idea is that subtracting a negative is the same as adding a positive.
负数也会在温度、银行余额等情景中出现，你将学习用数轴来排序、加减负数。核心概念是：减去一个负数等于加上它的相反数。
4. Fractions, Decimals and Percentages | 分数、小数和百分比
different ways of representing the same proportion. You will learn to convert between them – for example, ½ = 0.5 = 50% fractions and simplifying fractions are key skills, as is finding a fraction of an amount.
Year 7 会把分数、小数和百分比联系起来，说明它们表示同一个比例的不同方式。你将学习它们之间的互化，例如 ½ = 0.5 = 50%。等值分数和约分是核心技能，求一个数量的几分之几也很重要。
Operations with fractions include adding and subtracting fractions with different denominators by finding a common denominator. You will also multiply and divide fractions by whole numbers, laying the groundwork for more complex calculations later. For decimals, addition, subtraction, multiplication and division are practised with clear attention to decimal point alignment.
分数运算包括通过找公分母来加减异分母分数，还会练习用整数乘除分数，为后续更复杂的计算打基础。小数方面，会重点练习加减乘除，特别注意小数点的对齐。
Understanding percentages as 'out of 100' helps you find percentages of amounts and solve problems involving discounts, interest and comparisons. You will also meet the link between percentage and decimal multipliers for the first time.
理解百分比是“每100份中的量”后，你能求出某个数量的百分比，并解决折扣、利息和比较的问题。你也会初次接触百分比与小数乘数之间的联系。
5. Introduction to Algebra: Using Letters and Expressions | 代数入门：使用字母和表达式
Algebra is often the biggest leap for Year 7 students. It starts by using letters to represent unknown numbers or variables. You will learn to write simple expressions, such as n + 5 or 3m, and to understand the meaning of terms, coefficients and the absence of a written multiplication sign.
代数是 Year 7 学生中最大的跨越。它从使用字母代表未知数或变量开始。你将学习写出简单的表达式，如 n + 5 或 3m，并理解项、系数的含义，以及省略乘号的惯例。
expressions and use simple formulas, such as finding the perimeter of a rectangle using P = 2l + 2w.
合并同类项是你最先掌握的代数技能之一。例如 2a + 5a 可简化为 7a。你还会将数值代入表达式，使用简单公式，比如用 P = 2l + 2w 求长方形的周长。
Sequences provide a visual introduction to algebra. You will recognise patterns, find term‑to‑term rules and begin to describe the nth term. This builds logical thinking and prepares you for working with functions and equations later on.
数列为代数提供了直观的引入。你会识别规律，找出逐项规则，并开始描述第 n 项。这有助于锻炼逻辑思维，为后续的函数和方程学习做准备。
6. Geometry: Shapes, Angles and Symmetry | 几何：图形、角度和对称
Geometry in Year 7 extends your knowledge of 2D and 3D shapes. You will classify quadrilaterals, triangles and polygons using properties such as side length, parallel lines and symmetry. Terms like 'isosceles', 'scalene', 'parallelogram' and 'rhombus' become part of your active vocabulary.
Year 7 的几何会拓展你对二维和三维图形的认识。你会根据边长、平行线和对称性等性质对四边形、三角形和多边形进行分类，'等腰'、'不等边'、'平行四边形'和'菱形'等术语将成为你的常用词汇。
Angle facts are central: you will learn that angles on a straight line sum to 180°, angles around a point total 360°, and vertically opposite angles are equal. You will measure and draw angles with a protractor, and calculate missing angles without measuring by applying these rules.
角度知识是重点：你将学习直线上的角之和为180°，一点周围的角之和为360°，对顶角相等。你会用量角器测量和画角，并运用这些规律在不测量的情况下计算未知角度。
Symmetry is explored through reflective symmetry in 2D shapes and the order of rotational symmetry. You might also build 3D shapes from nets and begin to visualise plans and elevations, which strengthens spatial reasoning.
对称部分会探讨二维图形的轴对称和旋转对称的阶数。你也可能通过展开图制作三维图形，并开始想象三视图，从而增强空间推理能力。
7. Measures and Units: Length, Area and Volume | 测量与单位：长度、面积和体积
for example, 1.5 km = 1500 m) is practised regularly, and you will start to work with compound units like km/h.
在 Year 7，你将统一使用标准公制单位：长度用毫米、厘米、米、千米；质量用克、千克；容量用毫升、升。单位换算（如 1.5 km = 1500 m）会经常练习，你还会开始涉及复合单位，如 km/h。
Perimeter of straight‑ ll also find the area of a triangle as half the base times the perpendicular height: A = ½ × b × h.
直线图形的周长通过边长相加求得。面积从长方形着手，再到组合长方形，使用公式 A = l × w。你还会学习三角形面积，即底乘高的一半：A = ½ × b × h。
oughout this topic, estimation and checking for reasonableness are emphasised, helping you develop number sense in measurement contexts.
长方体体积用 V = l × w × h 计算，结果用立方单位表示。整个主题中会强调估算和检查答案的合理性，帮助你在测量情境中培养数感。
8. Statistics: Collecting and Interpreting Data | 统计：收集与解释数据
Data handling becomes more structured in Year 7. You will design survey questions, collect primary data and organise it into frequency tables. Tally charts and grouped frequency tables are used to record data efficiently.
Year 7 的数据处理更加系统化。你会设计调查问题，收集原始数据，并将其整理成频数表。计数符号和分组频数表被用来高效记录数据。
You will represent data using bar charts, pictograms and line graphs, paying attention to scales, labels and titles. The meaning of discrete and continuous data is introduced, helping you choose the best way to display each type.
你将用条形图、象形图和折线图展示数据，并注意刻度、标签和标题。课程会介绍离散数据和连续数据的含义，帮助你为每种数据选择最佳展示方式。
The three averages – mean, median and mode – are calculated from lists and frequency tables. You will also find the range as a measure of spread. Interpreting what these statistics tell you about a data set is just as important as calculating them.
三个平均数——均值、中位数和众数——会从列表和频数表中计算。你还会找出极差作为离散程度的度量。理解这些统计量对数据集的含义，与计算它们同样重要。
9. Problem Solving and Reasoning | 问题解决与推理
Problem solving is woven throughout the WJEC Year 7 curriculum. You will tackle multi‑step word problems, puzzles and open‑ended investigations where there is often more than one correct approach. The focus is on breaking down a problem, choosing a strategy and persevering when stuck.
问题解决贯穿 WJEC Year 7 课程。你会处理多步骤文字题、谜题和开放式探究题，它们常有不止一种正确解法。重点在于分解问题、选择策略并在遇到困难时坚持不懈。
Reasoning means explaining 'why' rather than just giving the answer. You will be asked to prove, justify and compare methods. For example, you might explain why the sum of angles in a triangle is 180°, or convince a partner that two fractions are equivalent using a diagram.
推理意味着解释“为什么”而不只是给出答案。你会被要求证明、验证和比较方法。例如，解释为什么三角形内角和是180°，或用图示说服同伴两个分数是等值的。

持续练习是提高数学最有效的方法。每周进行几次短时间的专注练习，而不是考前突击。利用在线资源、抽认卡和 WJEC 官网的历年试题，让复习形式多样化。
Always show your working out, even if you think the answer is obvious. This helps your teacher see your thinking and makes it easier to spot small mistakes. Keep a maths notebook where you write down important rules and examples in your own words.
即使答案看起来很明显，也要写下解题步骤。这能让老师看到你的思路，也便于发现小错误。准备一本数学笔记本，用自己的语言记下重要的规则和例题。
Don't be afraid to ask questions. If a concept feels unclear, speak to your teacher, work with a study partner, or try explaining it aloud to yourself. Teaching someone else is often the best way to check your own understanding.
不要害怕提问。如果某个概念不清楚，可以问老师、与学习伙伴讨论，或尝试给自己大声讲解。教别人往往是检验自己理解程度的最好方式。
12. Preparing for Assessments and Building Confidence | 准备评估与建立信心
In Year 7 you will have regular end‑of‑topic tests and possibly a termly exam. The best preparation is to review your classwork, correct any errors in your exercise book, and practise similar questions. Focus on understanding the methods, not just memorising steps.
Year 7 会有定期的单元测试，可能还有阶段考试。最好的准备是复习课堂作业，订正练习册中的错误，并练习类似题目。重在理解方法，而不仅仅是记住步骤。
Try to see assessments as a chance to show what you can do rather than something to fear. Use feedback from your teacher to set yourself one small target for improvement each time. Over the year, these small steps add up to big progress.
试着把评估看作展示自己能力的机会，而不是害怕的事情。根据老师的反馈，每次为自己设定一个小改进目标。一年下来，这些小进步会累积成大突破。
Finally, celebrate your successes and reflect on how far you've come. Mathematics is a subject where persistence and a positive attitude really do make a difference. Welcome to Year 7 – enjoy the challenge and take pride in every new skill you build.
最后，庆祝你的成功并回顾自己的成长。在数学这门学科中，坚持和积极的态度真的能带来改变。欢迎来到 Year 7——享受挑战，为每一次新技能的掌握感到自豪。
