How to Read and Write Numbers for the 11+ UK Exam

Understanding how to read and write numbers is an essential skill that will serve you well in the 11+ exam and beyond. This article will provide clear guidance on these important concepts, helping you gain confidence in your mathematical abilities.

Understanding Place Value

First, let’s talk about place value. Every digit in a number has a specific value based on its position. For instance, in the number 4,562:

The 4 is in the thousands place, meaning it represents 4,000.

The 5 is in the hundreds place, representing 500.

The 6 is in the tens place, representing 60.

The 2 is in the units (or ones) place, which means it represents 2.

Key Points:

Always read numbers from left to right.

Recognize the value of each digit according to its position.

Reading Numbers Aloud

When it comes to reading numbers aloud, clarity is crucial. Break larger numbers into manageable parts and read each part according to its place value.

Examples:

1,234 is read as "one thousand two hundred thirty-four."

56,789 is read as "fifty-six thousand seven hundred eighty-nine."

Practice:

Try reading these numbers aloud:

3,456

78,910

1,005

Writing Numbers in Words

Writing numbers in words requires precision. Use hyphens for compound numbers (from 21 to 99) and commas to separate thousands.

Examples:

1,234 is written as "one thousand two hundred thirty-four."

45,678 is written as "forty-five thousand six hundred seventy-eight."

Tips for Writing:

Break down the number into parts: thousands, hundreds, tens, and units.

Use "and" when necessary, especially in British English. For example, "one hundred and five."

Understanding Different Types of Numbers

Whole Numbers

These are the basic counting numbers, including zero (0, 1, 2, 3, ...). For instance, 150 is a whole number.

Decimal Numbers

Decimal numbers include a decimal point and represent fractions. For example, 3.14 is read as "three point one four."

Fractions

Fractions indicate parts of a whole. For instance, 1/2 is written as "one half," and 3/4 is written as "three quarters."

Practice Exercises

Exercise 1: Read Aloud

2,345

67,890

1,200

Exercise 2: Write in Words

102

Exercise 3: Identify Place Value

Identify the place value of the underlined digits:

56,789 (What is the value of 6?)

4,234 (What is the value of 2?)

Conclusion

Mastering how to read and write numbers is crucial for the 11+ exam and everyday life. By understanding place value, practicing reading aloud, and writing numbers accurately in words, you'll build a strong foundation for success in mathematics and other subjects. Keep practicing, and you’ll improve your skills in no time!
