从小学升入中学是一个激动人心的里程碑,在苏格兰,由 P7 进入 S1 意味着数学学习将迎来新的挑战。卓越课程(CfE)框架通过其“体验与成果”设定了明确的进阶路线,大多数 P7 学生正朝着第二级末端努力,并准备好接触第三级的内容。本指南旨在帮助你理解需要熟练掌握的关键数学领域,提供实用的复习建议,并建立应对更复杂课题的信心。无论你是正在为升学做准备的学生、在家支持学习的家长,还是规划针对性辅导的老师,这些见解都将帮助你平稳地完成衔接。
1. Understanding Number Systems | 认识数系
A solid grasp of place value, rounding, and the base-ten number system is fundamental. You should be able to read, write, and compare whole numbers up to at least 1,000,000, and decimals to three places. Being able to round numbers to the nearest ten, hundred, or decimal place is a skill used daily in secondary maths, from estimating answers to checking calculator work.
牢固掌握位值、四舍五入以及十进制数系是一项基本功。你应该能够读写并比较至少达 1 000 000 的整数,以及三位小数。能够将数字四舍五入到最近的十、百或小数位,是中学数学中每日都会用到的技能,无论是估算答案还是检验计算器结果。
| Place Value Heading | 位值标题 | Example | 示例 |
|---|---|
| Millions | 5 600 000 |
| Hundred Thousands | 600 000 |
| Ten Thousands | 50 000 |
| Thousands | 3 000 |
| Hundreds | 400 |
| Tens | 20 |
| Units / Ones | 5 |
Practise rounding numbers like 3476 to the nearest 100 (3500) and decimals like 14.378 to two decimal places (14.38). In S1, you will extend this to significant figures and standard form, so a strong number sense is essential.
练习将诸如 3476 的数字四舍五入到最近的百(3500),以及将 14.378 这样的小数四舍五入到小数点后两位(14.38)。进入 S1 后,你将把这些知识拓展到有效数字和科学记数法,因此扎实的数感必不可少。
2. Fractions, Decimals and Percentages | 分数、小数和百分比
Being able to switch between fractions, decimals and percentages is a core Third Level expectation. You need to recognise equivalent fractions, simplify fractions, and find fractions of quantities. Interchanging common fractions like 1/2 = 0.5 = 50%, 1/4 = 0.25 = 25%, 3/4 = 0.75 = 75%, and 1/10 = 0.1 = 10% should be second nature.
能够在分数、小数和百分比之间自由转换是第三级的一项核心要求。你需要识别等值分数、约分,并求出一个数量的几分之几。像 1/2 = 0.5 = 50%、1/4 = 0.25 = 25%、3/4 = 0.75 = 75% 以及 1/10 = 0.1 = 10% 这样的常见分数转换应成为你的第二天性。
Calculating percentages of amounts — such as 15% of 200 — and using percentages in real-life contexts like discounts or interest builds numeracy. In secondary school, you will link fractions, decimals and percentages with ratio and proportion, and solve problems such as sharing £120 in the ratio 3:5.
计算一个数量的百分比——例如 200 的 15%——以及在折扣或利息等现实情境中使用百分比,能够培养数感。在中学,你会把分数、小数和百分比与比和比例联系起来,并解决诸如将 £120 按 3:5 分配等问题。
3. Working with Negative Numbers | 负数的运算
P7 learners should confidently add and subtract negative integers. You must visualise temperature scales, bank balances, or lifts going below ground level to understand the effect of adding a negative or subtracting a negative. For example, 3 − (−2) = 3 + 2 = 5.
P7 学生应当自信地进行负整数的加减运算。你需要借助温度计刻度、银行余额或低于地面的电梯等情景,理解加上一个负数或减去一个负数的效果。例如,3 − (−2) = 3 + 2 = 5。
Secondary mathematics expects you to multiply and divide with negative numbers. Remember the rule: if the signs are the same, the answer is positive; if the signs are different, the answer is negative. So (−4) × (−3) = 12, while (−6) ÷ 2 = −3.
中学数学则要求你进行负数的乘除运算。记住这条规则:同号得正,异号得负。因此 (−4) × (−3) = 12,而 (−6) ÷ 2 = −3。
4. Introduction to Algebra | 代数入门
Algebra begins by using letters to represent unknowns or general rules. You should be comfortable forming expressions from statements, such as ‘I think of a number, add 5, then multiply by 2’ becomes 2(n + 5). Collecting like terms — for instance, simplifying 3a + 2b − a + 4b to 2a + 6b — is a skill that will be used in every maths lesson from S1 onwards.
代数从用字母表示未知数或通用规则开始。你应当能轻松地从文字描述中列出表达式,诸如“我想一个数,加 5,再乘 2” 写作 2(n + 5)。合并同类项——例如将 3a + 2b − a + 4b 化简为 2a + 6b——是 S1 起每堂数学课都会用到的技能。
Substituting values into formulas, like finding the area of a rectangle using A = l × w when l = 5 cm and w = 3 cm, shows the power of algebra in everyday problem solving. Practise evaluating expressions like 3x + 7 for x = 2, 0, and −1.
将数值代入公式,例如当 l = 5 cm、w = 3 cm 时用 A = l × w 求矩形面积,展示了代数在日常问题解决中的威力。练习计算诸如 3x + 7 在 x = 2、0 和 −1 时的值。
5. Solving Simple Equations | 求解简单方程
At the transition stage, you should be able to solve one-step and two-step equations. This means using inverse operations to find the value of the unknown. For example, to solve 4x = 20, divide both sides by 4 to get x = 5; to solve p + 9 = 15, subtract 9 from both sides to give p = 6.
在衔接阶段,你应当会解一步和两步方程。这意味着运用逆运算来求出未知数的值。例如,解 4x = 20,两边同除以 4 得到 x = 5;解 p + 9 = 15,两边同减去 9 得到 p = 6。
Building up to two-step equations like 2y − 3 = 11, first add 3 to both sides (2y = 14) and then divide by 2 (y = 7). In S1, you will apply these skills to problems with brackets and variables on both sides, so getting the balance method right is crucial.
逐步上升到 2y − 3 = 11 这样的两步方程,先两边同时加 3(2y = 14),再除以 2(y = 7)。在 S1 中,你会将这些技能应用到带括号以及两边都有未知数的题目中,因此掌握平衡方法至关重要。
6. Shapes and Symmetry | 形状与对称性
You should be able to name and describe 2D shapes including triangles (equilateral, isosceles, scalene) and quadrilaterals (square, rectangle, parallelogram, rhombus, kite, trapezium). Understanding the properties — number of sides, equal sides, parallel lines, angles — allows you to classify shapes correctly.
你应当能说出并描述二维图形,包括三角形(等边三角形、等腰三角形、不等边三角形)和四边形(正方形、矩形、平行四边形、菱形、风筝形、梯形)。理解它们的性质——边数、相等边、平行线、角——能让你正确地对图形进行分类。
Lines of symmetry and rotational symmetry are important concepts. A square has 4 lines of symmetry and rotational symmetry of order 4, whereas an equilateral triangle has 3 lines of symmetry and order 3. In S1, you will use these properties to make tessellations and solve problems involving coordinates.
对称轴和旋转对称是重要的概念。正方形有 4 条对称轴,旋转对称的阶为 4;而等边三角形有 3 条对称轴,阶为 3。在 S1 中,你将利用这些性质制作镶嵌图案并解决涉及坐标的问题。
7. Angles and Lines | 角和线
Measuring angles with a protractor, drawing angles accurately, and estimating sizes are continued from primary. You must know that angles on a straight line add up to 180°, angles around a point total 360°, and vertically opposite angles are equal.
用量角器测量角度、准确地画出角以及估算角的大小,这些是从小学延续上来的技能。你必须知道直线上的角之和为 180°,绕某一点的角之和为 360°,以及对顶角相等。
In secondary mathematics, you will explore angle rules within parallel lines — corresponding, alternate, and vertically opposite angles — and begin to use these to calculate missing angles without measuring. For instance, if two parallel lines are cut by a transversal, the alternate angles are equal, so a 50° angle implies its alternate is also 50°.
在中学数学中,你将探究平行线中的角规则——同位角、内错角——并开始运用这些规则来计算未知角度而无需测量。例如,两条平行线被一条横截线所截,内错角相等,因此一个 50° 的角意味着它的内错角也是 50°。
8. Measurement and Units | 测量与单位
Converting between metric units (km, m, cm, mm; kg, g; litre, ml) is expected. You should recall relationships like 1 km = 1000 m, 1 m = 100 cm, 1 kg = 1000 g. Simple calculations of perimeter of rectilinear shapes and area of rectangles (area = length × width) need to be accurate and quick.
你需要能够在公制单位(千米、米、厘米、毫米;千克、克;升、毫升)之间进行换算。你应当记得诸如 1 km = 1000 m、1 m = 100 cm、1 kg = 1000 g 这样的关系。对直线形周长和矩形面积(面积 = 长 × 宽)的简单计算必须做到准确且迅速。
S1 will introduce compound units like speed (km/h), area of triangles, and volume of cubes and cuboids. Being comfortable with decimal measurements and using formulas is key. Practise finding the perimeter of a shape with sides 3.5 m, 2.2 m and 4.3 m, and the area of a rectangle of length 8 cm and width 5 cm.
S1 将引入复合单位,如速度(km/h)、三角形的面积以及正方体和长方体的体积。对带小数的测量感到自如并会使用公式是重点。练习求一个边长分别为 3.5 m、2.2 m 和 4.3 m 的图形的周长,以及求长为 8 cm、宽为 5 cm 的矩形面积。
9. Handling Data and Statistics | 数据处理与统计
Reading and interpreting bar charts, line graphs and pictograms is second nature by P7. You should be able to find the mean, median, mode and range of a simple data set, for example: 5, 8, 8, 12, 17. The mean is (5+8+8+12+17) ÷ 5 = 10, the mode is 8, the median is 8, and the range is 17 − 5 = 12.
到 P7 时,读懂并解释条形图、折线图和象形统计图已经是你的基本功了。你应当能找出一组简单数据的平均数、中位数、众数和极差,例如:5, 8, 8, 12, 17。平均数是 (5+8+8+12+17) ÷ 5 = 10,众数是 8,中位数是 8,极差是 17 − 5 = 12。
In secondary school, you will create and compare sets of data, use spreadsheets, and draw pie charts using the fraction of the whole. Simple probability — expressed as a fraction, decimal or percentage — also starts here: if a bag contains 3 red and 5 blue counters, the probability of drawing a red counter is 3/8.
在中学,你将创建并比较数据集,使用电子表格,并利用部分占整体的分数来绘制饼图。简单的概率——以分数、小数或百分比表示——也从这里开始:如果一个袋子里有 3 个红色和 5 个蓝色筹码,抽到一个红色筹码的概率是 3/8。
10. Time and Timetables | 时间与时间表
Reading 12-hour and 24-hour clock times, calculating time intervals, and interpreting bus or train timetables are essential life skills. You should be able to work out that if a film starts at 14:35 and lasts 1 hour 50 minutes, it finishes at 16:25.
读懂 12 小时制和 24 小时制时间、计算时间间隔以及解读公交或火车时刻表是重要的生活技能。你应当能算出,如果一部电影在 14:35 开始,持续 1 小时 50 分钟,那么它将在 16:25 结束。
S1 work extends this to speed, distance and time problems using the formula: speed = distance ÷ time. Time calculations become linked with algebra and ratio, so ensure you can change minutes to hours accurately — for example, 45 minutes is 0.75 hours.
S1 的学习会将其拓展到运用公式“速度 = 距离 ÷ 时间”解决速度、距离和时间问题。时间计算将与代数和比例关联起来,因此确保你能准确地将分钟转换为小时——例如,45 分钟等于 0.75 小时。
11. Problem-Solving Strategies | 问题解决策略
Mathematics is not just about calculations; it is about applying logical thinking. You will be asked to work through multi-step problems, identify the operation needed, and sometimes check if your answer makes sense in the context. Drawing a diagram or making a table can often transform a puzzling question into a clear solution.
数学不仅仅是计算,它更是逻辑思维的应用。你会被要求解决多步骤问题,确定所需运算,有时还要检验答案在该语境中是否合理。画图或列表常常能将一个令人困惑的问题转化为清晰的解法。
A practical example: ‘A garden is in the shape of a rectangle 12 m long and 8 m wide. A border of flowers 1 m wide is planted around the outside edge. What area remains for grass?’ Break it down: the grass area is a smaller rectangle with length (12 − 2) m = 10 m and width (8 − 2) m = 6 m, giving an area of 60 m².
一个实际例子:“一个花园呈矩形,长 12 m,宽 8 m。沿外围边缘种植了一圈 1 m 宽的花卉。剩下种草的面积是多少?” 分步解决:草地是一个较小的矩形,长 (12 − 2) m = 10 m,宽 (8 − 2) m = 6 m,因此面积为 60 m²。
12. Tips for a Smooth Transition | 顺利衔接的小贴士
Keep a positive mindset towards maths — mistakes are part of learning. Review your times tables regularly; rapid recall of multiplication facts up to 12 × 12 frees your brain for higher-level reasoning. Use online tools like Sumdog, BBC Bitesize (Mathematics Third Level) or the National Numeracy website to practise little and often.
保持积极的数学心态——错误是学习的一部分。定期复习乘法口诀;对 12 × 12 以内乘法的迅速反应能释放你的大脑空间,用于更高级的推理。利用 Sumdog、BBC Bitesize(第三级数学)或 National Numeracy 网站等在线工具,进行少量多次的练习。
Talk through problems aloud. Explaining your reasoning to a parent or friend helps cement your understanding. Before starting S1, try a few past revision worksheets from CfE materials; they often combine number, shape and data into thematic challenges, giving you a flavour of what’s to come.
把问题大声地说出来。向父母或朋友解释你的推理过程有助于巩固理解。在升入 S1 前,可以尝试做几份 CfE 材料的复习练习题;这些练习常常将数字、图形与数据融合在主题挑战中,让你提前感受未来的学习内容。
Finally, stay organised: having a maths toolkit — ruler, protractor, compass, calculator — and keeping a dedicated notebook for maths vocabulary will make you feel prepared and confident from the very first day.
最后,保持有条不紊:准备好一个数学工具包——直尺、量角器、圆规、计算器——并保留一本专门的数学词汇笔记本,这会让你从第一天起就感到准备充分且充满信心。
