📚 Grade 4 Maths Test: Core Skills and Practice | 四年级数学测试：核心技能与练习

In a Grade 4 maths test, students are expected to work with larger whole numbers, apply the four operations, understand basic fractions and decimals, measure using standard units, describe shapes, and read simple graphs. The test usually mixes quick calculation questions with word problems that require careful reading and clear working.

在四年级数学测试中，学生需要掌握较大的整数、运用四种基本运算、理解基础分数和小数、使用标准单位进行测量、描述图形以及阅读简单图表。测试通常将快速计算题与需要仔细读题和清晰列式的应用题结合起来。

1. Number Sense and Place Value | 数感与位值

Place value is the foundation of almost every Grade 4 question. Students must read, write, compare and round numbers up to at least 10 000, and often up to 100 000 or 1 000 000 in some curricula.

位值是几乎所有四年级题目的基础。学生必须会读、写、比较和四舍五入至少到 10 000 的数，在许多课程中还会扩展到 100 000 甚至 1 000 000。

In the number 47 382, the digit 4 is in the ten-thousands place and represents 40 000; the digit 7 is in the thousands place and represents 7 000.

在数字 47 382 中，数字 4 位于万位，表示 40 000；数字 7 位于千位，表示 7 000。

Comparing numbers requires checking the highest place value first. For example, 56 210 > 55 999 because the ten-thousands digits are equal, but 6 000 is greater than 5 000.

比较数字时要先看最高位。例如 56 210 > 55 999，因为万位相同后，6 000 大于 5 000。

Rounding rules are also tested: to round 3 476 to the nearest hundred, look at the tens digit 7, so round up to 3 500.

四舍五入规则也会考查：将 3 476 四舍五入到百位，看十位数字 7，因此进位到 3 500。

• 4 725 in expanded form: 4 000 + 700 + 20 + 5. 4 725 展开式：4 000 + 700 + 20 + 5。
• Round 3 476 to the nearest hundred: 3 500. 将 3 476 四舍五入到百位：3 500。

2. Addition and Subtraction | 加法与减法

Grade 4 tests include multi-digit addition and subtraction with regrouping, often up to 5-digit numbers. Students need accurate column methods and estimation to check answers.

四年级测试包括多位数的加法和减法，通常涉及最多五位数的进退位。学生需要准确的竖式方法和估算来检查答案。

For 7 456 + 2 389, align digits by place value and carry when a column total is 10 or more. The sum is 9 845.

计算 7 456 + 2 389 时，按位值对齐，某列相加满 10 要进位。结果是 9 845。

For 9 203
