📚 Year 7 CCEA Further Maths: Summer Prep & Bridging Course | 七年级CCEA进阶数学：暑期预习与衔接课程
This summer prep course is designed for students transitioning into Year 7 to build a solid foundation in CCEA Further Maths. It bridges the gap between primary-level numeracy and the more challenging topics of Key Stage 3, ensuring a confident start in September.
本暑期预习课程旨在帮助即将升入七年级的学生为CCEA进阶数学打下坚实基础。课程衔接小学数学与关键阶段三更具挑战性的课题，确保学生九月开学时充满信心。
1. Number Systems and Place Value | 数系与位值
A strong grasp of place value is essential for all further work. You will read, write and order numbers up to ten million, recognising the value of each digit depending on its position. Decimal place value extends to thousandths, and you will compare numbers like 3.452 and 3.46 by looking at tenths, hundredths and thousandths.
牢固掌握位值是全部后续学习的基础。你需要能够读写并排序最大到千万的数，识别每一位数字根据位置所代表的值。小数位值精确到千分位，你会通过比较十分位、百分位和千分位来比较像 3.452 和 3.46 这样的数。
Pupils often underestimate how important it is to multiply and divide by 10, 100 and 1000 quickly. In CCEA Further Maths, you will use this skill when converting between units and working with metric measures. The digits shift to the left or right rather than the decimal point moving, which helps you keep track of place value logic.
同学们常常低估快速乘除以 10、100 和 1000 的重要性。在 CCEA 进阶数学中，你会利用这一技能在单位换算和公制度量计算中。数字本身向左或向右移动，而并非小数点移动，这有助于你保持位值的逻辑。
2. Fractions, Decimals and Percentages | 分数、小数与百分数
You will link fractions, decimals and percentages as different ways of describing parts of a whole. Being able to convert between these forms – for example, knowing that 3/5 = 0.6 = 60% – is a core skill. You will also learn to order a mix of these numbers accurately by converting them to the same form first.
你需要将分数、小数和百分数视为描述整体部分的不同方式。能够在这些形式之间转换——例如知道 3/5 = 0.6 = 60%——是一项核心技能。你还会学习通过先将它们转化为同一种形式来准确排序混合数。
Calculations with fractions go beyond simple addition; in Year 7 you will add and subtract fractions with different denominators using a common denominator. Multiplication and division of proper and improper fractions are also covered, including the “keep, change, flip” method for division.
分数的计算超出简单加法；在七年级你会学习使用公分母来加减不同分母的分数。还会学习真分数和假分数的乘除法，包括除法的“保、变、倒”方法。
Percentages are applied to real-life contexts such as finding discounts or calculating interest. You will learn to find a percentage of a quantity without a calculator by breaking it into 10%, 5% and 1% building blocks.
百分数被应用到生活中，例如计算折扣或利息。你会学习不用计算器求一个数量的百分数，方法是将其拆分为 10%、5% 和 1% 的组合模块。
3. Working with Negative Numbers | 负数运算
Negative numbers are formally introduced and used in contexts such as temperature, bank balances and elevation. You will learn to add and subtract negative numbers using a number line, remembering that subtracting a negative is the same as adding a positive.
负数正式引入，并用于温度、银行余额和海拔等情境。你将学习使用数轴进行负数的加减，记住减去一个负数等同于加上一个正数。
Multiplication and division of negative numbers follow clear rules: a positive times a negative gives a negative, and a negative times a negative gives a positive. These rules are consistently practised with simple examples like (−3) × (−4) = 12 and (−12) ÷ 3 = −4.
负数的乘除法遵循明确的规则：正数乘负数得负数，负数乘负数得正数。通过简单例子如 (−3) × (−4) = 12 和 (−12) ÷ 3 = −4 反复练习这些规则。
4. Introduction to Algebra | 代数初步
Algebra is the language that lets you express patterns and relationships without writing out long lists of numbers. You will learn to use letters to stand for unknown values, and to write simple expressions such as 3n + 5 to describe a sequence.
代数是一种语言，让你不必写出长串数字就能表达模式和关系。你将学习用字母表示未知数，并写出诸如 3n + 5 的简单表达式来描述数列。
You will simplify expressions by collecting like terms. For example, 2a + 3b + 5a − b can be simplified to 7a + 2b. You will also learn to expand brackets using the distributive law, so that 3(x + 4) becomes 3x + 12.
你通过合并同类项来化简表达式。例如 2a + 3b + 5a − b 可化简为 7a + 2b。你还会学习运用分配律展开括号，使得 3(x + 4) 变成 3x + 12。
Substituting values into algebraic expressions is another key skill; you will replace letters with given numbers and evaluate the result, carefully following the order of operations (BIDMAS).
将数值代入代数表达式是另一项关键技能；你将用给定数字替换字母并计算出结果，严格遵循运算顺序（括号、指数、乘除、加减）。
5. Solving Simple Equations | 解简易方程
Once you can write algebraic expressions, the next step is to solve equations. You will work with one-step and two-step equations, such as x + 5 = 12 and 3y − 4 = 11. The balance method – doing the same thing to both sides – is the central idea.
一旦你能写出代数表达式，下一步就是解方程。你将学习一步和两步方程，如 x + 5 = 12 和 3y − 4 = 11。天平法——对方程两边同时进行相同运算——是核心思想。
You will learn to check your answer by substituting it back into the original equation. This habit is encouraged in CCEA questions to reduce careless mistakes. Word problems are also introduced to translate real situations into equations.
你将学习通过将答案代入原方程来检验。CCEA 题目鼓励这个习惯以减少粗心错误。还会引入文字题，将真实情境转化为方程。
6. Sequences and Patterns | 数列与规律
You will explore number sequences, identify the rule that generates them, and find missing terms. Sequences may increase or decrease by the same amount each step (arithmetic sequences) or follow a pattern like doubling.
你将探究数列，找出生成数列的规则，并确定缺失项。数列可以每一步增加或减少相同的量（等差数列），也可以遵循加倍等模式。
The nth term is introduced as a formula to find any term in a sequence without listing all previous ones. For a sequence like 4, 7, 10, 13, …, the nth term is 3n + 1. You will learn to generate terms and link the formula to the pattern.
引入第 n 项，作为求序列中任意一项的公式，而不必列出之前所有项。对于数列 4, 7, 10, 13, …，第 n 项为 3n + 1。你将学习生成各项并将公式与规律联系起来。
7. Properties of Shapes and Angles | 图形性质与角度
You will classify 2D shapes by their properties, including triangles (scalene, isosceles, equilateral) and quadrilaterals (square, rectangle, parallelogram, rhombus, trapezium). Key properties such as parallel sides and equal angles are used to identify them.
你将根据性质对二维图形进行分类，包括三角形（不等边、等腰、等边）和四边形（正方形、矩形、平行四边形、菱形、梯形）。利用平行边、等角等关键性质来识别图形。
Angle facts are fundamental: angles on a straight line sum to 180°, angles around a point sum to 360°, and vertically opposite angles are equal. You will use these to find missing angles without measuring.
角度知识是基础：直线上的角度和为 180°，一点周围的角度和为 360°，对顶角相等。你将利用这些知识不测量直接求出未知角。
8. Perimeter, Area and Volume | 周长、面积与体积
You will move beyond simple counting of squares to using formulas for the area of rectangles, triangles and compound shapes. The area of a rectangle is length × width, while a triangle is half the base × perpendicular height. These formulas are memorised and applied.
你将超越简单的数格子方法，使用公式计算矩形、三角形及组合图形的面积。矩形面积为 长 × 宽，三角形面积为 ½ × 底 × 垂直高。这些公式需要记忆并应用。
Perimeter is the distance around the edge of a shape. For compound shapes made from rectangles, you will learn to find missing side lengths and then sum all the edges. Volume of cubes and cuboids is calculated using the formula length × width × height.
周长是图形边缘的总长度。对于由矩形构成的组合图形，你将学习找出缺失边长，然后全部相加。正方体和长方体的体积使用公式 长 × 宽 × 高 来计算。
9. Data Handling and Averages | 数据处理与平均数
You will collect, represent and interpret data using bar charts, pictograms and line graphs. In CCEA courses, you are often asked to compare two sets of data and draw conclusions based on the graph.
你将使用条形图、象形图和线图来收集、展现并解读数据。在 CCEA 课程中，常要求你比较两组数据并根据图表得出结论。
The three averages – mode, median and mean – are introduced. You will learn to find the median by ordering numbers and locating the middle value, and to calculate the mean by dividing the total by the number of values. The range measures spread.
介绍三种平均数——众数、中位数和均值。你将学习通过将数字排序并找出中间值来求中位数，并通过总和除以数值个数来计算均值。极差用来衡量离散程度。
10. Ratio, Proportion and Rates | 比、比例与速率
Ratio compares parts to parts, and you will simplify ratios in their simplest form, just like fractions. If a recipe uses 200 g of flour and 100 g of sugar, the ratio is 2 : 1. You will solve problems involving sharing an amount in a given ratio.
比用来比较部分与部分，你将像分数一样把比化为最简形式。如果食谱使用 200 g 面粉和 100 g 糖，比为 2 : 1。你将解决按给定比例分配数量的问题。
Proportion problems often involve scaling up or down. You will use the unitary method to find the value of one item and then multiply. Rates such as speed (km/h) or unit price connect two different units and are calculated by division.
比例问题常涉及扩大或缩小。你将使用归一法求出单个物品的值然后再相乘。速率如速度（km/h）或单价，连接两种不同单位，并通过除法计算。
11. Graphs and Coordinates | 图表与坐标
You will plot points in the first quadrant and eventually in all four quadrants using coordinates (x, y). This links algebra and geometry: you can draw simple lines such as y = x and y = 2x + 1 by creating a table of values and plotting points.
你将首先在第一象限，最终在所有四个象限内使用坐标 (x, y) 描点。这联系了代数与几何：你可以通过制作数值表并描点来画出 y = x 和 y = 2x + 1 这样的简单直线。
Understanding the meaning of the gradient is a sneak preview of Key Stage 3 work. A steeper line has a larger coefficient of x. You will also read information from distance-time graphs and understand how the slope represents speed.
理解斜率的意义是对关键阶段三学习的前瞻。越陡的线 x 的系数越大。你还会从距离-时间图中读取信息，并理解斜率如何表示速度。
