Cambridge Primary Mathematics Workbook 2 (2nd Edition) is designed for young learners aged 6–7, helping them build a strong foundation in key mathematical concepts through engaging and varied exercises. This article provides a detailed breakdown of the question types found in the workbook, offering insights into the skills each section develops and practical tips for effective learning.
《剑桥小学数学练习册2》第二版专为6–7岁的小学习者设计，通过丰富多样的练习帮助他们打下坚实的数学基础。本文将对练习册中的题型进行详细解析，说明每个部分所培养的技能，并提供高效学习的实用建议。
1. Counting and Number Recognition | 数数及数字识别
Exercises in this section focus on reading, writing, and sequencing numbers up to 100. Typical questions include completing number lines, filling in missing numbers in sequences such as 23, 24, __, 26, and matching written numbers to numerals. These tasks reinforce counting forwards and backwards, as well as recognising patterns in the number system.
该部分的练习侧重于100以内数字的读写与排序。典型题目包括完成数轴、在如23, 24, __, 26的数列中填入缺失数字，以及将文字数字与阿拉伯数字进行匹配。这些任务能够强化正向与反向数数能力，并帮助儿童识别数字系统中的模式。
A common question type presents a partially filled hundred square and asks the learner to write the missing numbers. This develops both number sense and spatial awareness of the number grid.
常见题型之一是提供一幅部分填充的百数表，要求学习者写出缺失的数字。这既培养了数感，也增强了对数字网格空间位置的认识。
2. Place Value and Partitioning | 位值与拆分
Learners explore the concept of tens and ones through a variety of representations. Questions often show bundles of ten sticks and single sticks, or ask pupils to decompose a two‑digit number like 47 into 4 tens and 7 ones. Matching activities and cut‑and‑stick exercises are also used to reinforce partitioning.
学习者通过多种表现形式探索十位与个位的概念。题目常常展示成捆的十根小棒和单根小棒，或要求学生将47这样的两位数拆分为4个十和7个一。匹配活动和剪贴练习也常用来巩固拆分技能。
Another typical format presents a number in a place value chart and asks children to identify the digit in the tens column or to build the number from given parts. This prepares them for formal column addition and subtraction later.
另一种常见形式是在位值表中给出一个数字，让孩子找出十位上的数字，或者根据给定的部分组合出该数字。这为后续的正式竖式加减法做好准备。
| Tens | Ones |
| 5 | 3 |
53 = 5 tens + 3 ones
3. Addition and Subtraction Strategies | 加减法策略
This section moves from concrete addition within 20 to two‑digit calculations. Question types include number bond diagrams, part‑whole models, and number line jumps. Learners are encouraged to use strategies such as counting on, making ten, and using known facts to solve problems like 28 + 5 or 63 − 9.
本部分从20以内的具体加法逐渐过渡到两位数计算。题型包括数字关系图、部分‑整体模型和数轴跳跃。鼓励学习者使用继续数数、凑十法以及利用已知事实等策略来解决诸如28 + 5或63 − 9这样的问题。
Word problems appear frequently, requiring pupils to read a short story, identify the operation, and write a number sentence. For example: ‘Sam has 34 stickers. He gives 12 to a friend. How many stickers are left?’ The answer is often recorded as a subtraction equation.
应用题频繁出现，要求学生阅读一个简短的故事，确定运算方式并写出算式。例如：‘Sam有34张贴纸，他给了朋友12张。还剩多少张贴纸？’答案通常以减法等式记录。
4. Multiplication and Division Introduction | 乘除法入门
Early multiplication is introduced through equal groups and arrays. Questions might show a picture of 3 plates with 4 cookies on each and ask for the total number, helping children connect repeated addition (4 + 4 + 4) with multiplication (3 × 4). Division is presented as sharing or grouping, e.g. ‘Share 15 pencils equally among 3 pots.’
初识乘法通过相等组和阵列引入。题目可能展示一张图片：3个盘子，每个盘子里有4块饼干，要求计算总数，从而帮助孩子将重复加法（4 + 4 + 4）与乘法（3 × 4）联系起来。除法以分享或分组的形式呈现，例如‘将15支铅笔平均分到3个笔筒中’。
Workbook 2 uses simple multiplication tables for 2, 5 and 10. Skip‑counting sequences and missing‑factor problems (e.g. __ × 2 = 10) are also included to build fluency.
练习册2涵盖2、5和10的简单乘法表。还包含跳数序列和缺失因数问题（例如__ × 2 = 10），以培养运算的流利度。
5. Fractions: Halves, Quarters, Thirds | 分数：二分之一、四分之一、三分之一
Fraction work begins with recognising ½ and ¼ of shapes and sets. Questions often show a circle divided into equal parts with some parts shaded and ask the learner to write the fraction. Learners also find ½ of a quantity, e.g. colour ½ of 8 stars.
分数学习从识别图形和集合的½和¼开始。题目常常展示一个被等分的圆，其中部分涂色，要求学习者写出相应的分数。学习者还需找出一个数量的½，例如将8颗星星中的½涂色。
A typical problem‑solving question provides a shape with 4 equal parts, 3 shaded, and asks ‘What fraction is not shaded?’ This encourages understanding of the whole. The workbook also introduces ⅓ using practical sharing contexts.
典型的解决问题题目会给一个4等分的图形，其中3份涂色，并问‘未涂色的部分占几分之几？’这促进了对整体的理解。练习册还通过实际分享情境引入⅓。
6. Measurement: Length, Mass, and Capacity | 测量：长度、质量和容量
Measurement tasks involve comparing and ordering objects by length, mass and capacity using non‑standard units such as paper clips or hand spans, and later centimetres. Learners measure lines to the nearest centimetre and compare lengths using phrases like ‘longer than’ and ‘shorter than’.
测量任务涉及使用回形针或手拃等非标准单位以及之后的厘米来比较和排序物体的长度、质量和容量。学习者需要将线条测量到最接近的厘米，并用‘比…长’、‘比…短’等短语比较长度。
Mass activities often show balance scales and ask which object is heavier or lighter. Capacity problems involve estimating and measuring how many cups fill a jug, linking to early volume concepts.
质量活动通常展示天平，并询问哪个物体更重或更轻。容量问题涉及估算和测量一个壶能装满多少杯水，与早期的体积概念联系起来。
7. Money and Time | 货币与时间
Money exercises use coins up to $1 (or the equivalent local currency) to practise counting, making given amounts, and finding change. A question might ask: ‘How many 5¢ coins make 20¢?’ or ‘Draw the coins you need to buy an item costing 65¢.’
货币练习使用面值不超过1美元的硬币（或等值的当地货币）来练习数钱、凑出指定金额以及找零。题目可能会问：‘多少个5¢硬币能凑成20¢？’或‘画出你购买一个65¢物品所需要的硬币。’
Time work focuses on reading analogue clocks to the half hour and quarter hour, and sequencing daily events. Children match clock faces to written times and draw hands on blank clocks for given times such as half past 3.
时间部分侧重于认读模拟钟表到半小时和刻钟，以及为日常事件排序。孩子们需要将钟面与书写的时间匹配，并在空白钟面上画出给定时间（如3点半）的指针。
8. 2D and 3D Shapes | 二维与三维图形
Learners identify and describe common 2D shapes (circle, triangle, square, rectangle, pentagon) and 3D shapes (cube, cuboid, sphere, cylinder, pyramid, cone) by their properties. Questions ask for the number of sides and corners, or to sort shapes into groups.
学习者识别并描述常见的二维图形（圆形、三角形、正方形、长方形、五边形）和三维图形（立方体、长方体、球体、圆柱体、棱锥、圆锥）的特征。题目要求说出边和角的数量，或对图形进行分类。
Symmetry is introduced by completing a symmetrical picture on a grid or identifying a line of symmetry in simple shapes. Patterns involving shapes and turns are also included to develop spatial reasoning.
通过完成网格上的对称图画或识别简单图形的对称轴来引入对称概念。还包括涉及图形与旋转的模式，以发展空间推理能力。
9. Position and Direction | 位置与方向
Directional language such as left, right, above, below, between, and next to is practised through grid‑based activities. A typical task gives a starting position and a set of directions, e.g. ‘Move 2 squares right, then 1 square up. Where are you now?’
通过基于网格的活动练习左、右、上、下、之间、旁边等方位语言。典型任务是给出起始位置和一组方向指令，例如‘向右移动2格，再向上移动1格。你现在在哪里？’
Another question type uses a simple map or classroom plan and asks pupils to describe the position of one object relative to another. This links mathematics with real‑world navigation and reinforces precise vocabulary.
另一种题型利用简单地图或教室平面图，要求学生描述一个物体相对于另一个物体的位置。这将数学与真实世界的导航相联系，并强化精确的词汇使用。
10. Data Handling: Pictograms and Block Graphs | 数据处理：象形图和方块图
Learners collect, organise and represent data using tally charts, pictograms (where one symbol represents one unit), and simple block graphs. Questions often require completing a pictogram from given data or interpreting a graph to answer ‘how many more?’ and ‘how many altogether?’
学习者使用计数表、象形图（一个符号代表一个单位）和简单的方块图来收集、整理和展示数据。题目常常要求根据给定数据完成象形图，或解读图表回答‘多多少？’和‘一共多少？’等问题。
A frequent exercise shows a block graph of favourite fruits and asks: ‘Which fruit is the most popular?’ or ‘How many more children chose apples than bananas?’ This develops the ability to draw conclusions from data.
常见练习是展示一张关于最喜爱水果的方块图，并问：‘哪种水果最受欢迎？’或‘选择苹果的孩子比香蕉的多几人？’这培养了从数据得出结论的能力。
11. Problem Solving and Reasoning | 问题解决与推理
Throughout the workbook, problem‑solving tasks are integrated to encourage logical thinking. These may be in the form of missing‑number puzzles, word problems requiring two steps, or ‘What if?’ scenarios. For instance: ‘I think of a number, add 10, then subtract 3. The answer is 25. What was my number?’
练习册中贯穿了问题解决任务，以鼓励逻辑思考。这些任务可能以缺失数字谜题、需要两步计算的应用题或‘如果…会怎样？’情境的形式出现。例如：‘我想一个数，加上10，再减去3，答案是25。我想的数是多少？’
Reasoning questions ask learners to explain their thinking, identify errors in a given solution, or decide whether a statement is always, sometimes or never true. These develop higher‑order skills and prepare children for more advanced mathematical challenges.
推理类题目要求学习者解释自己的思路、找出给定解法中的错误，或判断某个说法是‘总是’、‘有时’还是‘从不’正确。这培养了高阶思维能力，为孩子迎接更高级的数学挑战做好准备。
