In Year 10 CCEA Further Mathematics, you are often asked to write short investigative essays or structured reports on mathematical topics. A clear writing frame helps you organise your thoughts, present logical reasoning and communicate your findings effectively. This article introduces a practical framework for writing mathematics papers, explains each section’s purpose, and provides a complete model essay on Pythagorean triples so you can see how the structure works in practice.
在 Year 10 CCEA 进阶数学课程中，你经常需要就某个数学主题撰写简短的探究性论文或结构化报告。清晰的写作框架有助于组织思路、呈现逻辑推理并有条理地交流你的发现。本文先介绍实用的数学论文写作框架，解释各部分的功能，然后提供一篇关于毕达哥拉斯三元数组的完整范文，让你直观地掌握这一结构的实际运用。
1. Why Are Writing Frames Important in Mathematics? | 为什么写作框架在数学中很重要？
Mathematics is not only about getting the right answer; it is also a discipline of logical thinking and clear communication. When you write a mathematics essay, a predictable structure makes your argument easier to follow and shows the examiner that you have planned your work carefully. A framework also helps you include all the required elements, from stating a clear aim to discussing limitations.
数学不仅在于得到正确答案，它也是一门逻辑思考与清晰表达的学科。撰写数学论文时，一个可预期的结构能让你的论证更易于理解，并向阅卷者展示你已经认真规划了整项工作。框架还能帮助你囊括所有必要环节，从明确陈述目标到讨论局限性，无一遗漏。
Using a writing frame reduces the risk of presenting disconnected calculations or rambling paragraphs. Instead, your essay will move smoothly through a problem, its investigation, and a well-supported conclusion. For CCEA tasks, this structured approach often aligns directly with the marking criteria for communication and reasoning.
使用写作框架可以降低出现杂乱计算或漫无边际段落的可能性。相反，你的论文会有条理地推进问题、展开探究并得出有充分支撑的结论。在 CCEA 的任务中，这种结构化的方式常常直接契合交流与推理部分的评分标准。
2. Overview of a Mathematics Essay Writing Frame | 数学论文写作框架概览
A typical frame for a short investigative essay contains seven core sections: Title and Abstract, Introduction and Aim, Methodology, Presentation of Findings, Discussion and Analysis, Conclusion, and References. Depending on the task, you may also include appendices for raw data or extra tables. Keeping each section focused makes your essay more professional and easier to evaluate.
典型的简短探究论文框架包含七个核心部分：标题与摘要、引言与目标、方法、发现展示、讨论与分析、结论以及参考文献。根据任务要求，你可能还需要附上附录，用于呈现原始数据或补充表格。让每个部分重点突出，能让你的论文更显专业，也更便于评价。
In Year 10, your essay will usually be between 600 and 1000 words. That means each section must be concise. The writing frame is a guide, not a rigid rule; you can adapt it to fit your investigation. For example, a pure proof-based essay might blend ‘Methodology’ and ‘Presentation of Findings’ into one continuous argument.
在 Year 10 阶段，你的论文通常在 600 至 1000 词之间，这意味着每个部分必须简明扼要。写作框架是指导性原则，而非死板规定，你可以根据探究需要灵活调整。例如，一篇纯证明类论文可以把“方法”与“发现展示”融合成一段连贯的论证。
3. Section 1: Title and Abstract | 第一环节：标题与摘要
The title should be precise and descriptive, not vague. A good title tells the reader exactly what you investigated and perhaps the context. For instance, ‘Investigating Patterns in Pascal’s Triangle Modulo 3’ is far stronger than ‘Maths Essay’. The abstract is a short summary (about 50-80 words) that states your aim, the method used, the main findings and the key conclusion.
标题应当精准且具描述性，避免空泛。一个好的标题能让读者准确了解你探究的内容及其背景。例如，“帕斯卡三角形模3下模式的探究”就远比“数学论文”有说服力。摘要是一段简短总结（约50—80词），需要点明你的目标、所用方法、主要发现和关键结论。
Write the abstract last, even though it appears first. This ensures it accurately reflects what you actually did and discovered. Use plain English and avoid introducing new symbols or unexplained terms in the abstract.
尽管摘要位于论文开头，但要留到最后才写。这样可以保证它准确地反映你的实际工作与发现。使用平实的语言，不要在摘要中引入新符号或未加解释的术语。
4. Section 2: Introduction and Aim | 第二环节：引言与目标
The introduction sets the scene. Start with a brief contextual sentence that explains why the topic is interesting or relevant. Then clearly state your investigation’s aim, often in the form: ‘The aim of this investigation is to explore…’ or ‘This essay will examine whether…’ You should also list two or three specific questions you intend to answer.
引言设定写作背景。先用一两句简要交代为什么该主题引人关注或具有相关性，然后明确陈述你的探究目标，常采用以下形式：“本探究旨在探索……”或“本文将考察……是否成立……”。你还应该列出两到三个拟回答的具体问题。
For CCEA further mathematics, linking the introduction to a known theorem or a real-life application can demonstrate wider understanding. For example, if you are studying quadratic equations, you might mention their use in projectile motion before focusing on the relationship between coefficients and roots.
在 CCEA 进阶数学中，把引言与一个已知定理或现实应用联系起来能展示你的广博理解。例如，如果你在学习二次方程，可以在聚焦系数与根的关系之前，先提到它们在抛体运动中的应用。
5. Section 3: Methodology and Approach | 第三环节：方法与路径
Here you explain how you carried out your investigation. Did you use algebra, trial and improvement, a computer spreadsheet, or a geometric approach? Describe your steps so clearly that another student could replicate your work. If you generated data systematically, explain the range of values you chose and why.
此处你要说明你是如何进行探究的。你使用了代数推导、试错法、电子表格还是几何方法？清晰描述你的操作步骤，让另一位同学也能重现你的工作。如果你系统地生成了数据，需解释选择该数值范围的理由。
Be honest about any limitations in your approach. For example, if you tested only positive integers up to 50, acknowledge that the pattern might not hold for larger numbers. This shows critical thinking and often earns higher marks in CCEA reasoning criteria.
对你的方法中的任何局限性都要坦诚。比如，如果你只测试了不超过 50 的正整数，那么要承认该模式对更大数值可能不成立。这体现了批判性思维，并常常能在 CCEA 推理标准中获得更高分数。
6. Section 4: Presenting Findings Clearly | 第四环节：清晰地展示发现
Your findings are the heart of the essay. Present them in a logical order, using a combination of text, equations and visual aids. Never simply dump a table without explanation; instead, guide the reader through what the data shows. Use phrases like ‘Table 1 reveals that…’ or ‘The initial results suggest a linear relationship because…’
你的发现是论文的核心。要按逻辑顺序呈现，综合运用文字、方程和可视化辅助手段。绝不要把表格丢在那儿不加解释；相反，要引导读者读懂数据显示的信息。可以使用“表1揭示了……”或“初步结果表明存在线性关系，因为……”这样的表述。
When you include equations, display them on separate centred lines for clarity. For example, if you discover a pattern, you might write the general term as:
Tₙ = 3n² – 2n + 5
然后你可以跟进一句解释：where n is the position in the sequence. 使用下标ₙ和上标²这类 Unicode 字符，使排版整洁清晰。
在呈现方程时，应使用单独的居中行，使其更醒目。比如，当你发现某个模式时，可以写出通项。接着用一句话解释，如“其中 n 为数列中的位置”，从而保持清晰的逻辑链条。
7. Section 5: Using Graphs, Tables and Diagrams Effectively | 第五环节：有效使用图形、表格与图表
Visual elements like graphs, tables and geometric diagrams can often convey a pattern more powerfully than words alone. Every visual must have a numbered caption, such as ‘Figure 1: Graph showing the growth of Fibonacci numbers’. In the text, refer to each figure by its number, never by ‘the graph below’.
图形、表格和几何图表等视觉元素往往比纯文字更能有力地传达模式。每处视觉材料都必须有带编号的标题，如“图1：展示斐波那契数增长的折线图”。在正文中，务必使用编号来指代图形，切勿写“下图”之类的表述。
For a short essay, avoid cluttering your work with too many visuals. One well-chosen graph and one structured table are usually enough. If you create a table, use borders that make the data easy to read, and always label the rows and columns clearly. A typical table style might look like this:
对于一篇短文，要避免堆砌过多视觉材料。一张精心挑选的图表和一张结构清晰的表格通常就足够了。制作表格时，应使用边框使数据易于阅读，并清晰地标注行与列。典型的表格样式如下：
| n | Term (aₙ) | Difference |
|---|---|---|
| 1 | 2 | – |
| 2 | 5 | 3 |
| 3 | 10 | 5 |
| 4 | 17 | 7 |
This table shows the first four terms of a sequence and their first differences. The consistent increase in the differences points towards a quadratic rule, which you would then discuss in the analysis section.
该表给出了数列的前四项及其一阶差分。差分呈现出的规律性增加暗示着一种二次规律，你可以在后续的分析部分中加以讨论。
8. Section 6: Discussion and Analysis of Patterns | 第六环节：讨论与分析模式
The discussion is where you interpret what you have found. Do not simply repeat the results; instead, explain why the patterns might occur and connect them to underlying mathematical principles. If your findings follow a known theorem, state the theorem and show how your data illustrates it. For example, you might note that ‘the observed relationship x² – y² always factorised as (x – y)(x + y), which is consistent with the difference of two squares identity’.
讨论部分是你解读发现的地方。不要简单地复述结果，而是要解释这些模式为何可能出现，并把它们与深层的数学原理联系起来。如果你的发现符合某个已知的定理，就明确指出这个定理并说明数据如何印证了它。比如，你可以指出“观察到的关系式 x² – y² 总可以因式分解为 (x – y)(x + y)，这与平方差恒等式一致”。
If your investigation produced an unexpected outcome, this is the ideal place to suggest a reason. Maybe the sample size was too small, or an odd-even effect was at play. Being critical about your own work demonstrates higher-order thinking and is specifically rewarded in many CCEA mark schemes.
如果你的探究出现了意料之外的结果，这正是提出可能原因的绝佳时机。也许是样本量太小，又或者是奇偶性效应在起作用。对自己的工作进行批判性思考，能展现高阶思维能力，在许多 CCEA 评分方案中都有专门体现。
9. Section 7: Drawing a Strong Conclusion | 第七环节：得出有力的结论
The conclusion should directly answer the questions you posed in the introduction. Summarise your main findings in a few sentences and state whether your aim was achieved. Avoid introducing any brand new information or leaving the reader with vague statements. A strong conclusion often includes a brief reflection on the reliability of the findings and a suggestion for further investigation.
结论应当直接回答你在引言中提出的问题。用几句话总结主要发现，并说明你的目标是否达成。避免引入任何全新的信息，也不要让读者面对模棱两可的陈述。有力的结论常常还包括对发现可靠性的简要反思，以及对进一步探究的建议。
For example, you could write: ‘The investigation confirmed that all primitive Pythagorean triples with legs up to 50 can be generated by the Euclid formula using coprime m and n of opposite parity. A natural extension would be to explore whether non-primitive triples with very large numbers behave in the same way.’ This shows completeness and curiosity.
例如，你可以写：“本探究证实，所有直角边不超过50的原始毕达哥拉斯三元数组均可由欧几里得公式通过互质且奇偶性相反的 m、n 生成。一个自然的延伸是探究非常大的非原始三元数组是否也表现出相同规律。”这既体现了完整性，也展示了好奇心。
10. Section 8: Referencing and Appendices | 第八环节：参考文献与附录
Even a Year 10 essay should acknowledge any sources you used, such as textbooks, websites or class notes. A simple reference list at the end is sufficient. Use a consistent format, for example: ‘Author, Title, Year’ for books and ‘Website Title, URL, Date accessed’ for online sources. Proper referencing adds credibility and helps you avoid plagiarism.
即便是 Year 10 阶段的论文，也应列出你所使用的任何来源，如教科书、网站或课堂笔记。在文末附上一个简单的参考文献列表就足够了。使用一致格式，例如书籍采用“作者, 书名, 年份”，网络来源采用“网站标题, URL, 访问日期”。恰当的引用可以增加可信度，并帮助你避免剽窃。
If you have extensive raw data, large tables or computer code that would interrupt the flow of the essay, place them in an appendix. Label appendices as Appendix A, Appendix B, and so on, and refer to them in the main text. This keeps your essay clean while still providing complete evidence.
如果你有大量的原始数据、大型表格或计算机代码，放在正文中会打断行文流畅性，则可将其置于附录。将附录标记为附录A、附录B等，并在正文中加以引用。这样可以在保持论文简洁的同时，仍然提供完整的证据。
11. Model Essay: Exploring Primitive Pythagorean Triples | 范文：探索原始毕达哥拉斯三元数组
The following model essay illustrates how to apply every part of the writing frame to a genuine Year 10 further mathematics investigation. The topic is primitive Pythagorean triples — sets of three positive integers (a, b, c) such that a² + b² = c² with no common factor greater than 1.
下面这篇范文展示了如何将写作框架的每一个环节应用到真实的 Year 10 进阶数学探究中。探究主题是原始毕达哥拉斯三元数组——即满足 a² + b² = c² 且最大公因数仅为 1 的三个正整数 (a, b, c)。
Title: An Investigation into the Generation of Primitive Pythagorean Triples Using Euclid’s Formula
Abstract: This investigation explores how primitive Pythagorean triples can be generated systematically. Using Euclid’s formula with coprime integers m > n of opposite parity, ten triples were produced and verified. The results confirm that the formula yields all primitive triples under 100. A small geometric extension explores the connection to unit circles.
标题：利用欧几里得公式生成原始毕达哥拉斯三元数组的探究
摘要：本探究探索如何系统地生成原始毕达哥拉斯三元数组。运用欧几里得公式，选取互质且奇偶性相反的 m > n，共生成并验证了十组三元数组。结果证实，该公式能产生所有小于 100 的原始三元数组。一项简短的几何延伸探讨了这些三元数组与单位圆的关联。
Introduction: Pythagorean triples have fascinated mathematicians for millennia. While any multiple of (3,4,5) gives a valid triple, the ‘primitive’ triples form the fundamental building blocks. The aim was to investigate Euclid’s generating formula a = m² – n², b = 2mn, c = m² + n² and to identify the conditions that guarantee primitivity.
引言：毕达哥拉斯三元数组数千年来一直让数学家着迷。虽然 (3,4,5) 的任何倍数都能给出有效的三元数组，但“原始”三元数组才是基本构件。本探究的目标是考察欧几里得生成公式 a = m² – n², b = 2mn, c = m² + n²，并找出保证原始性的条件。
Methodology: A systematic approach was adopted. All pairs (m, n) with m ≤ 7 and n < m were listed. Pairs were filtered so that m and n are coprime and one is even, the other odd. For each qualifying pair, a, b and c were computed and checked both numerically and algebraically. The GCD of each triple was also verified.
方法：采用系统化方法。列出所有满足 m ≤ 7 且 n < m 的数对 (m, n)。然后筛选出 m、n 互质且一奇一偶的配对。对每一符合条件的配对，计算 a、b、c，并从数值与代数两方面检验，同时验证每组三元数组的最大公因数。
Findings: The formula successfully generated (3,4,5), (5,12,13), (8,15,17), (7,24,25) and six more. All were primitive. A clear pattern emerged: when m and n are consecutive in the filtered list, the a-values follow a difference of successive odd numbers. A small table summarised the first five triples and their derived properties.
发现：公式成功生成了 (3,4,5)、(5,12,13)、(8,15,17)、(7,24,25) 等六组。全部为原始三元数组。出现了一个清晰的模式：当 m 和 n 在筛选列表中是连续值时，a 值的差值与连续奇数相关。一个小表格概括了前五组三元数组及其推导出的性质。
Discussion: The condition that m and n be coprime and of opposite parity proved to be both necessary and sufficient within the tested range. The b-values were always even, which is expected since 2mn is always even. Any deviation, such as using m = 4, n = 2 (not coprime), gave a non-primitive triple (12,16,20), which is simply 4 × (3,4,5), confirming the importance of the coprime condition.
讨论：在测试范围内，互质且奇偶性相反这一条件被证明是必要且充分的。b 值恒为偶数，这在意料之中，因为 2mn 总是偶数。任何违反条件的情况，比如使用 m = 4, n = 2（不互质），会产生非原始三元数组 (12,16,20)，它不过是 (3,4,5) 的 4 倍，印证了互质条件的重要性。
Conclusion: Euclid’s formula, when restricted to coprime m, n of opposite parity, reliably generates all primitive Pythagorean triples up to c < 100. The investigation met its aim and highlighted the deep link between number theory and geometry. Future work could explore rational points on the unit circle generated by these triples.
结论：当限制 m、n 互质且奇偶性相反时，欧几里得公式能可靠地生成所有 c < 100 的原始毕达哥拉斯三元数组。本探究达成了目标，并凸显了数论与几何之间的深层联系。未来可以探索由这些三元数组生成的单位圆上的有理点。

12. Tips for Achieving High Marks in CCEA Further Mathematics Essays | 在 CCEA 进阶数学论文中获取高分技巧
Always read the task-specific mark scheme provided by your teacher or CCEA. Marks are typically allocated for communication, logical reasoning and mathematical accuracy. Ensure that your essay flows logically from aim to conclusion, and connect each section with transitional phrases such as ‘Building on this result…’ or ‘Contrary to the initial hypothesis…’
务必阅读教师或 CCEA 提供的任务专属评分方案。分数通常分配给交流、逻辑推理和数学准确性三个方面。确保你的论文从目标到结论一气呵成，并用过渡语连接各部分，比如“在此结果之上……”或“与最初假设相反……”。
Proofread your essay carefully. Spelling errors in mathematical terms (e.g., ‘triple’ instead of ‘triple’) can create confusion. Also, when you are asked to ‘investigate’, remember that exploration is valued — do not just present a single correct answer; show how you tested conjectures, what went wrong, and how you refined your approach.
认真校对你的论文。数学术语的拼写错误（如把 ‘triple’ 写成 ‘triple’）会造成混淆。此外，当题目要求你“探究”时，请记住探索的过程本身也是有价值的——不要仅仅展示一个正确答案；要展示你是如何检验猜想的、哪里走错了方向，以及你是如何改进方法的。
Finally, practise writing mini-essays under timed conditions. Start with simple investigations such as ‘Prove that the sum of three consecutive integers is divisible by 3’ and use the writing frame. Over time, the structure will become second nature, allowing you to focus on the mathematical creativity that makes a further mathematics essay truly stand out.
最后，请在限时条件下练习写作短篇论文。从简单的探究入手，比如“证明三个连续整数之和可被 3 整除”，并使用本写作框架。久而久之，结构将成为你的第二天性，让你能够专注于数学创造力，这正是让一篇进阶数学论文脱颖而出的关键。
