1. Course Introduction & Aims | 课程简介与目标
The CCEA Year 7 mathematics curriculum builds on the number work you have already mastered and introduces new areas such as algebra, formal geometry and statistical reasoning. This summer course focuses on closing any gaps from primary school and getting you familiar with the style of thinking required in secondary maths. You will learn to explain your reasoning, solve problems with multiple steps and begin to use mathematical notation fluently.
CCEA七年级数学课程是在你已经掌握的数字运算基础上，进一步拓展代数、规范几何和统计推理等新领域。本暑期课程的重点是弥补小学阶段可能存在的知识漏洞，并让你熟悉中学数学所需的思维方式。你将学会解释自己的推理过程、解决多步骤的问题，并开始熟练地使用数学符号。
By the end of this bridging course, you should feel comfortable with place value up to millions, negative numbers, fraction–decimal–percentage conversions, basic algebraic expressions and properties of shapes. Each section includes a summary of what CCEA expects, example questions and tips for studying effectively over the holiday.
完成本衔接课程后，你应该能够熟练处理百万以内的位值、负数、分数–小数–百分数的互化、基础代数表达式以及图形的性质。每一节都包含CCEA的期望要求、例题以及如何在假期中高效学习的建议。
2. Transition from Primary Arithmetic to Secondary Mathematics | 从小学算术到中学数学：关键转变
In primary school, much of the focus is on performing calculations accurately and quickly. In Year 7, you are still expected to calculate fluently, but you are also asked to describe methods, justify your choices and apply skills in unfamiliar contexts. Lessons will move faster, and you will meet topics like algebraic substitution and angle facts that rely on understanding rather than memorisation.
在小学，数学的重点往往是准确而快速地进行计算。到了七年级，你依然需要流畅地计算，但同时还要求你描述方法、论证自己的选择并在陌生的情境中应用技能。课堂进度会更快，你会遇到诸如代数代入和角度知识等更依赖理解而非记忆的课题。
CCEA assessment objectives for Year 7 include ‘using and applying mathematics’, which means you will see more word problems and real-life scenarios. The summer is a perfect time to practise reading a question carefully, identifying what it is asking and planning a solution—skills that many students find tricky at first.
CCEA对七年级的评估目标包括“运用和应用数学”，这意味着你会遇到更多的文字应用题和现实生活场景。暑假是练习仔细审题、识别问题要求并规划解题思路的绝佳时机——这些技能一开始往往让许多学生感到棘手。
3. Extending the Number System: Integers, Negatives and Place Value | 数系的扩展：整数、负数和位值
Year 7 students must be able to read, write, order and compare numbers up to at least one million, recognising the value of each digit. A solid understanding of place value is essential before moving on to decimals and large-number calculations. You should also be able to round any whole number to the nearest 10, 100 or 1000, and explain your rounding decisions.
七年级学生必须能够读写、排序和比较至少到一百万的数字，并理解每个数位的值。在学习小数和大数计算之前，牢固掌握位值概念至关重要。你还需要能够将任意整数四舍五入到最接近的十、百或千，并解释舍入的理由。
A typical CCEA question might ask you to arrange a set of numbers in descending order or to write a 6-digit number in words. The table below shows the place value columns for the number 3,456,789 as a quick revision aid.
典型的CCEA考题可能会要求你将一组数字按从大到小排列，或者用文字写出一个六位数。下面的表格以数字 3,456,789 为例，展示了各数位列，供快速复习参考。
| Millions | Hundred Thousands | Ten Thousands | Thousands | Hundreds | Tens | Ones |
| 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Negative numbers are introduced in Year 7 through real-life contexts such as temperature and bank balances. You will learn to order negative and positive integers on a number line, and to add and subtract with negative numbers using simple rules like ‘moving left for subtraction’ on the line. For example, 3 + (-5) can be visualised as starting at 3 and moving 5 places left, ending at -2.
负数在七年级通过温度和银行余额等现实生活情境引入。你将学习在数轴上排列负整数和正整数，并利用简单的规则（如在数轴上“减即向左移”）进行负数的加减运算。例如，3 + (-5) 可以想象为从3出发，向左移动5个单位，最终到达 -2。
4. Mastering Four Operations and Mental Strategies | 精通四则运算与心算策略
Efficient addition, subtraction, multiplication and division form the backbone of Year 7 mathematics. CCEA expects you to use formal column methods for larger numbers but also to develop mental strategies such as partitioning, compensating and using known number facts. Estimation is equally important: before you work out 27 × 43, you should be able to round to 30 × 40 = 1200 and know that the answer will be around 1200.
高效的加、减、乘、除运算是七年级数学的支柱。CCEA要求你既能用规范的竖式方法处理大数，也能发展心算策略，如拆分法、补偿法和利用已知数字事实。估算同样重要：在计算 27 × 43 之前，你应该能将其近似为 30 × 40 = 1200，并清楚答案应在1200左右。
Long multiplication and division can seem daunting, but breaking them into smaller steps makes them manageable. For instance, 123 × 45 can be thought of as 123 × 40 plus 123 × 5. That equals 4920 + 615, giving a total of 5535. Practising these calculations regularly over the summer will increase both speed and accuracy.
长乘法和长除法看似令人生畏，但将它们分解成小步骤就会变得易于处理。例如，123 × 45 可以看作 123 × 40 加上 123 × 5。这等于 4920 + 615，总和为 5535。暑假期间定期练习这类计算将同时提高速度和准确性。
Mental maths is also tested in short, timed activities. Learn tricks such as multiplying by 10, 100 and 1000 just by shifting digits, and using doubling and halving to simplify multiplication. For example, 16 × 25 is the same as 4 × 100 = 400, because 16 × 25 = (4 × 4) × 25 = 4 × (4 × 25).
心算能力也会通过限时的小测验来考查。可以学习一些技巧，比如通过数字移位来乘以10、100和1000，以及利用加倍和折半来简化乘法。例如，16 × 25 等同于 4 × 100 = 400，因为 16 × 25 = (4 × 4) × 25 = 4 × (4 × 25)。
5. Understanding Fractions, Decimals and Percentages | 理解分数、小数和百分数
In Year 7, you will use fractions, decimals and percentages interchangeably and must be able to convert between them fluently. CCEA expects you to recognise equivalent fractions, simplify fractions to their lowest terms, and compare fractions by finding a common denominator. You will also meet improper fractions and mixed numbers, learning to convert one form to the other.
在七年级，你将灵活地交替使用分数、小数和百分数，并且必须能够熟练地在它们之间进行转换。CCEA要求你识别等值分数、将分数化简为最简形式，并通过通分来比较分数大小。你还将遇到假分数和带分数，并学习两者之间的互化。
A key equivalence that should become automatic is shown below. Being able to recall this instantly saves time in tests and makes solving percentage problems much easier.
½ = 0.5 = 50%
Decimals are extended to three places in Year 7, so you should be comfortable with tenths, hundredths and thousandths. Ordering decimals is a common pitfall: remember that 0.7 is larger than 0.35, because 0.7 means 7 tenths while 0.35 is 35 hundredths. Using place value charts can help avoid confusion.
小数的学习在七年级扩展到三位小数，因此你应该熟练掌握十分位、百分位和千分位。小数的大小排序是一个常见的陷阱：请记住 0.7 比 0.35 大，因为 0.7 表示7个十分之一，而 0.35 是35个百分之一。使用位值表有助于避免混淆。
6. Introduction to Algebraic Thinking: Expressing Patterns with Letters | 代数思维入门：用字母表示规律
Algebra often causes anxiety, but Year 7 algebra is simply about using letters to stand for numbers and to describe patterns. You will learn to write expressions like 3n + 2 to represent a sequence, and to substitute numbers into simple formulae. For example, if n = 5, then 2n + 3 becomes 2 × 5 + 3 = 13.
代数常常引起焦虑，但七年级的代数其实只是用字母表示数字和描述规律。你将学习写出像 3n + 2 这样的表达式来表示一个数列，并学会将数字代入简单的公式。例如，如果 n = 5，那么 2n + 3 就等于 2 × 5 + 3 = 13。
CCEA introduces function machines in Year 7 as a visual way to understand the idea of a rule being applied to a number. Starting with an input, applying an operation and finding the output helps build the logic needed later for solving equations. A function machine that multiplies by 4 and then adds 1 can be written as 4x + 1, where x is any input number.
CCEA在七年级用函数机器作为一种直观的方式，帮助你理解规则应用于数字的概念。从输入开始，施加一种运算，再求出输出，这有助于培养日后解方程所需的逻辑思维。一个先乘以4再加1的函数机器可以写成 4x + 1，其中 x 是任意输入的数字。
You will also learn about collecting like terms in simple cases, such as simplifying 2a + 3a to 5a, and about the idea that multiplication signs are often omitted. 3 × y is written as 3y. These conventions are new but become second nature with a little practice.
你还将学习在简单情况下合并同类项，例如将 2a + 3a 化简为 5a，并了解乘号通常被省略的惯例。3 × y 写作 3y。这些约定是全新的，但只要稍加练习就会变得自然而然。
7. Exploring Shape, Space and Measures | 探索形状、空间与度量
Geometry in Year 7 moves beyond naming shapes to classifying them by their properties. You will identify acute, obtuse and right angles, estimate angle sizes, and use a protractor to measure angles accurately. Knowing that angles on a straight line add up to 180° and angles around a point total 360° is essential for problem solving.
七年级的几何学习不仅停留在说出图形的名称，而是要根据性质对其进行分类。你将识别锐角、钝角和直角，估算角度的大小，并使用量角器准确测量角度。明白直线上的角之和为 180° 以及围绕一点的角之和为 360° 是解决问题的基础。
Perimeter and area are studied in the context of rectangles and compound shapes. The key formulae that you must remember and apply are:
Perimeter of rectangle = 2 × (length + width)
Area of rectangle = length × width
Metric units are used throughout CCEA assessments. You should be able to convert between cm, m and km, and between g and kg. Understanding the relationship between millilitres and litres will also be tested in measurement problems. A common mistake is confusing area and perimeter; labelling answers with the correct units (e.g. cm for perimeter, cm² for area) helps reinforce the difference.
CCEA的评估中全部采用公制单位。你应该能够在厘米、米和千米之间进行换算，以及克与千克之间的换算。毫升与升之间的关系也将在测量问题中考查。一个常见的错误是混淆面积和周长；用正确的单位标记答案（如周长用 cm，面积用 cm²）有助于强化两者之间的区别。
8. Handling Data and Interpreting Charts | 数据处理与图表解读
The statistics strand in Year 7 introduces you to collecting, representing and interpreting data. You will design simple surveys, create frequency tables and display results using bar charts, pictograms and simple pie charts. CCEA questions often ask you to read information from a chart, explain what it shows and answer comparative questions like ‘which category is most popular?’.
七年级的统计学内容将引导你学习收集、展示和解读数据。你将设计简单的调查，创建频数表，并用条形图、象形图和简单的饼图呈现结果。CCEA的问题经常要求你从图表中读取信息，解释图表内容并回答比较性问题，例如“哪一类最受欢迎？”。
You will meet the concept of the mode (the most frequent value) and the range (the difference between the largest and smallest values). These are used to describe data sets. For example, a set of test scores {12, 15, 12, 18, 12, 20} has a mode of 12 and a range of 8. No advanced averages like mean or median are required at this stage, but being able to spot patterns is important.
你将接触到众数（出现最频繁的值）和范围（最大值与最小值之差）的概念，它们用来描述数据集。例如，一组考试分数 {12, 15, 12, 18, 12, 20} 的众数是 12，范围是 8。现阶段不要求掌握平均数或中位数等更高级的平均值，但能够发现数据中的规律十分重要。
Practise drawing bar charts with equal gaps between bars, labelling axes clearly and choosing a sensible scale. When the scale goes up in 2s, 5s or 10s, it is easy to misread a bar if you are not careful—a skill that CCEA examiners like to test.
练习绘制柱形之间间距相等的条形图，清晰地标记坐标轴，并选择合适的刻度。当刻度以2、5或10为递进单位时，如果不仔细，很容易误读柱形的高度——这也是CCEA考官喜欢考查的技能。
9. Developing Problem Solving and Reasoning Skills | 培养问题解决与推理能力
Across all CCEA topics, there is a strong emphasis on problem solving. You will be asked to break down a word problem, identify the mathematics needed, carry out the required calculations and interpret the result. Often, more than one step is required, and you may need to explain your method clearly.
CCEA的所有课题中都十分强调问题解决能力。你需要拆解文字题，识别所需的数学知识，执行必要的计算并解释结果。通常，问题需要不止一个步骤，而且你可能需要清晰地解释自己的方法。
A classic example: “A school bus holds 45 children. There are 128 children going on a trip. How many buses are needed?” The division gives 128 ÷ 45 = 2 remainder 38. Although the answer is 2 remainder 38, you need 3 buses because the remaining 38 children cannot be left behind. This is a ’round up’ interpretation that tests your understanding of context.
一个经典的例子是：“一辆校车可容纳45名儿童。有128名儿童要去旅行。需要多少辆校车？” 除法给出 128 ÷ 45 = 2 余 38。虽然计算结果是2余38，但实际上需要3辆校车，因为剩下的38名儿童不能留下。这是一种需要“向上舍入”的理解方式，考查你对实际情境的把握。
Reasoning involves making connections. For instance, if you know that 6 × 23 = 138, you can reason that 12 × 23 = 276, and that 60 × 23 = 1380. As you practise, try to explain your reasoning out loud or write it in simple sentences; this will strengthen your mathematical communication.
推理涉及建立联系。例如，如果你知道 6 × 23 = 138，就能推算出 12 × 23 = 276，以及 60 × 23 = 1380。在练习时，尝试出声解释或写成简单的句子，这将增强你的数学交流能力。
10. Summer Study Plan and Recommended Online Resources | 暑期学习计划与在线资源推荐
A little practice every day is far more effective than cramming at the end of the holiday. Aim for 20–30 minutes of focused maths activity five days a week. You could dedicate each day to a different topic: Monday for number skills, Tuesday for fractions, Wednesday for algebra basics, Thursday for shape and measures, and Friday for data handling. Weekends can be used for fun maths games or puzzles.
每天少量练习远比假期结束前突击有效得多。争取每周五天，每天进行20到30分钟的专注数学活动。你可以将每一天安排给不同的主题：周一练习数字技能，周二分数，周三代数基础，周四图形与测量，周五数据处理。周末则可以用来玩玩数学游戏或解谜。
