Year 7 OCR 数学课程以国家课程第三学段要求为基础，帮助学生扎实掌握数学的各个核心领域。课程从小学算术平稳过渡到更正式的数学思维方式，引入代数、几何、统计和概率。学生将学习逻辑推理、解决多步骤问题并清晰地表达解题方法。本指南将逐一拆解每个主要课题，让学生和家长清楚了解全年的学习内容和如何有效支持学习。
1. The OCR Approach and National Curriculum | OCR 教学思路与国家课程
The OCR Mathematics course for Year 7 aligns with the national curriculum, ensuring coverage of number, algebra, ratio, geometry, probability and statistics. Teachers use a mastery approach, meaning topics are studied in depth and students are expected to demonstrate fluency before moving on. Regular diagnostic checks identify gaps and provide stretch for high attainers.
OCR 的七年级数学课程与国家课程保持一致，涵盖数、代数、比、几何、概率和统计。教师采用精熟教学法，即深入探究每个课题，学生在展现流畅的解题能力后才会进入下一阶段。定期的诊断性测验能够查漏补缺，并为能力较强的学生提供挑战性任务。
Problem solving is embedded throughout, rather than treated as a standalone unit. Pupils are encouraged to use concrete resources, pictorial representations and abstract symbols to deepen understanding. The scheme promotes key skills such as reasoning, conjecturing and generalising from patterns.
问题解决能力贯穿整个课程，而非作为独立单元处理。鼓励学生使用实物教具、图示表征和抽象符号来加深理解。课程注重推理、提出猜想以及从模式中归纳概括等关键技能。
2. Number and Place Value | 数与位值
In Year 7, students extend their understanding of place value to include decimals and numbers up to one billion. They work with tenths, hundredths and thousandths, using place value charts to compare and order numbers confidently. Negative numbers are introduced in context, such as temperature and bank balances, and pupils learn to place them on a number line.
七年级学生将位值的理解扩展到小数及十亿以内的数。他们学习十分位、百分位和千分位，借助位值表熟练比较和排序数字。负数则通过温度、银行余额等情境引入，学生要学会在数轴上找到它们的位置。
Rounding is another core skill: students round integers to the nearest ten, hundred or thousand, and decimals to a given number of decimal places. They also explore powers of ten, linking multiplying and dividing by 10, 100 and 1000 to shifting digits left and right.
近似数是另一项核心技能：学生将整数近似到最近的十、百或千，将小数近似到指定的小数位数。同时他们探索十的幂，把乘除以10、100和1000与数字的位置移动联系起来。
3. Arithmetic Operations | 算术运算
Fluency in formal written methods for addition, subtraction, multiplication and division is a priority. Column addition and subtraction are extended to larger numbers, while short and long multiplication are practised with up to three-digit numbers and decimals. Long division is introduced step by step, often linking to the chunking method.
熟练运用竖式加法、减法、乘法和除法是重点。竖式加减法扩展到更大的数字，短乘法和长乘法练习包含三位数及小数。长除法逐步引入，常与分块法关联教学。

学生还需掌握运算顺序，借助BIDMAS或BODMAS口诀计算带括号、指数、除、乘、加、减的表达式。心算策略同步发展，例如运用补偿法和拆分法进行快速准确的心算。
4. Fractions, Decimals and Percentages | 分数、小数与百分数
Year 7 pupils deepen their work on equivalent fractions and learn to compare and order fractions with different denominators by finding common denominators. They convert between improper fractions and mixed numbers and perform all four operations with fractions, including adding and subtracting fractions with unlike denominators.
七年级学生深化对等值分数的理解，学会通过通分比较和排序不同分母的分数。他们能进行假分数与带分数的互化，并对分数进行四则运算，包括异分母分数的加减。
Decimals and percentages are tied closely to fractions. Students express one quantity as a percentage of another, convert between fractions, decimals and percentages, and solve percentage increase and decrease problems. This topic is essential for later work on ratio and proportion.
小数和百分数与分数紧密相连。学生能将一个量表示为另一个量的百分数，在分数、小数和百分数之间进行转换，并解决百分数的增减问题。这部分内容对之后的比和比例学习至关重要。
5. Algebra: Expressions and Equations | 代数：表达式与方程
essions and substitute positive integers into formulae. They simplify expressions by collecting like terms, understanding that 3a + 2a = 5a.
代数作为算术的一般化表达方式被引入。学生学会用字母符号表示变量，写出简单的代数表达式，并将正整数代入公式。他们通过合并同类项来化简表达式，理解3a + 2a = 5a。
. They learn to keep the equation balanced by performing the same operation on both sides, often checking their solutions by substitution.
解线性方程是一个重要的里程碑。从 x + 5 = 12 这样的一步方程开始，学生进而学习 2x + 3 = 11 这样的两步方程。他们学会通过在等号两边进行相同运算以保持方程平衡，并常通过代入检验答案。
6. Sequences, Functions and Graphs | 数列、函数与图像
The study of sequences develops pattern-spotting skills. Pupils generate terms of a linear sequence from a given term-to-term rule, such as 'add 4'. They also find the nth term of simple arithmetic sequences and use it to predict any term, for example the 100th term.
学习数列可以培养发现模式的技能。学生根据给定的项间法则（例如“每次加4”）生成线性数列的项。他们还能求出简单等差数列的第n项，并用它预测任意项，比如第100项。

绘制四个象限内的坐标得到巩固，学生开始绘制线性函数图像。他们为诸如 y = 2x + 1 这样的函数填制输入输出表，并将得到的数对描点，观察它们落在一条直线上。
7. Ratio and Proportion | 比与比例
Ratio notation is introduced as a way of comparing quantities. Pupils learn to simplify ratios by dividing both sides by a common factor and to share an amount in a given ratio, often using bar model diagrams to visualise the parts.
比的记法作为比较数量的方式被引入。学生学会通过除以公因数化简比，并按给定比例分配数量，常借助条形模型图来直观呈现各部分。
Proportion problems extend the idea to direct proportion. Students use multiplicative reasoning to scale recipes up or down and to solve 'best buy' problems, comparing unit prices. This topic strengthens links between ratio, fractions and multiplication.
比例问题延伸到正比例的概念。学生运用乘法推理来调整食谱分量，并通过比较单位价格解决“最佳购买”问题。这一课题强化了比、分数和乘法之间的联系。
8. Geometry: Angles and Shapes | 几何：角度与形状
Angle facts are consolidated and extended. Pupils measure and draw angles with a protractor, use angle notation, and apply rules: angles on a straight line sum to 180°, angles around a point sum to 360°, and vertically opposite angles are equal. They also calculate missing angles in triangles and quadrilaterals.
巩固并拓展角度知识。学生用量角器测量并绘制角，使用角度符号，并应用以下规则：直线上角之和为180°，一点周围角之和为360°，对顶角相等。他们还计算三角形和四边形中的未知角。
Properties of 2D shapes are explored in more depth. Pupils classify triangles by side lengths and angles, and quadrilaterals by symmetry and parallel sides. They use this knowledge to deduce further properties, such as the angle sum of a pentagon.
更深入地探究二维图形的性质。学生根据边长和角对三角形分类，根据对称性和平行边对四边形分类。他们运用这些知识推导更深层的性质，比如五边形的内角和。
9. Measures: Perimeter, Area and Volume | 测量：周长、面积与体积
Perimeter and area are formalised with standard units. Pupils find the perimeter of rectilinear shapes and the area of rectangles, triangles and parallelograms using formulae. They also calculate the area of compound shapes by splitting them into known figures.

10. Statistics and Data Handling | 统计与数据处理
Year 7 statistics focuses on collecting, representing and interpreting data. Pupils design surveys, create frequency tables and draw bar charts, pictograms and line graphs. They learn to choose the most appropriate diagram for a given data set and audience.
七年级统计学习的重点是收集、表示和解读数据。学生设计调查问卷，制作频数表，并绘制条形图、象形图和折线图。他们学会为一组给定数据和目标受众选择最合适的图表。
Averages are covered in depth: mode, median and mean. Students calculate the mean from a simple frequency table, understand the range as a measure of spread, and compare data sets using both the average and the range. This leads to simple statistical reasoning and decision-making.
深入理解平均数：众数、中位数和均值。学生从简单的频数表中计算均值，理解极差作为衡量离散程度的指标，并利用平均数和极差比较数据集。这导向简单的统计推理和决策。
11. Probability | 概率
The probability scale from 0 to 1 is introduced, with 0 meaning impossible and 1 meaning certain. Pupils use words like 'likely', 'unlikely', 'even chance' and assign numerical probabilities to simple events, such as rolling a number on a fair dice.
引入从0到1的概率标尺，0表示不可能，1表示必然。学生使用“很可能”、“不太可能”、“等可能性”等词语，并为简单事件分配数字概率，例如掷一个公平骰子得到某个数的概率。
They list all possible outcomes systematically and calculate probabilities of equally likely outcomes. Experimental probability is explored by carrying out simple trials and comparing relative frequency with theoretical probability, building a foundation for risk and chance in everyday contexts.
学生系统地列出所有可能的结果，并计算等可能结果的概率。通过简单的试验探索实验概率，将相对频数与理论概率进行比较，为日常情境中的风险和机会打下基础。
12. Problem Solving and How to Succeed | 问题解决与成功策略
Throughout Year 7, problem solving is woven into every topic. Pupils learn to read a word problem carefully, identify the mathematics needed, break it into manageable steps and check their answers for sense. Questions often combine two or more areas of maths, such as using algebra to solve a geometry problem.
整个七年级，问题解决贯穿每个课题。学生学会仔细阅读文字题，识别所需的数学知识，将其拆分为可处理的步骤，并检验答案的合理性。题目经常结合两个或多个数学领域，例如用代数解决几何问题。
