Have you ever wondered how a single digit like “5” can mean very different things depending on where it’s placed in a number? That’s the magic of place value—a foundational concept in primary school maths that helps children understand the value of digits based on their position in a number. Place value lays the groundwork for all future mathematical learning, from addition and subtraction to algebra and beyond.

Why Is Place Value Important in Maths?

  • It helps us read, write, and understand large numbers.

  • It allows us to perform calculations efficiently.

  • It builds number sense and mathematical reasoning.

  • It prepares students for decimals, fractions, and operations.

In the UK National Curriculum, place value is introduced as early as Year 1 and continues to be built upon up to Year 6. How to Solve Integration Problems

Understanding the Base-10 Number System

What Are Digits and Numbers?

A digit is a single symbol used to make numbers. In base-10, we use ten digits: 0 to 9. A number is a group of one or more digits. For example:

  • Digit: 4

  • Number: 42

How the Decimal System Works

Our number system is positional and base-10, which means:

  • Each place has a value 10 times more than the one to its right.

  • The rightmost place is the ones (or units).

  • Moving left, we have tens, hundreds, thousands, etc.

Place Value
Thousands 1,000
Hundreds 100
Tens 10
Ones 1

Place Value Chart for Primary School Students

Place value charts are visual tools that help children understand how digits form numbers. How to Write the Perfect Essay for GCSE English

Ones, Tens, Hundreds, Thousands

Thousands Hundreds Tens Ones
3 5 2 6

The number above is 3,526:

  • 3 in the thousands = 3,000

  • 5 in the hundreds = 500

  • 2 in the tens = 20

  • 6 in the ones = 6

Place Value Beyond Thousands

Ten Thousands Thousands Hundreds Tens Ones
2 3 4 5 6

This number is 23,456. Understanding extended place values helps learners deal with larger numbers confidently.

How to Read and Write Large Numbers

Using Commas and Number Groups

To make reading numbers easier, we group digits in threes starting from the right:

  • 1,000 (One thousand)

  • 10,000 (Ten thousand)

  • 100,000 (One hundred thousand)

Children should practise:

  • Saying numbers aloud

  • Writing numbers in words

  • Breaking numbers into expanded form

Example:
34,127 = 30,000 + 4,000 + 100 + 20 + 7

Place Value in Decimal Numbers

Tenths, Hundredths, and Thousandths

Decimals allow us to represent parts of a whole. In place value, decimal places come after the decimal point.

Ones . Tenths Hundredths Thousandths
3 . 1 4 7

This is 3.147:

  • 1 is in the tenths = 0.1

  • 4 is in the hundredths = 0.04

  • 7 is in the thousandths = 0.007

Comparing and Ordering Decimal Numbers

When comparing decimals:

  • Compare digits from left to right.

  • Use zeroes to match place values.
    0.5 = 0.50 = 0.500

Common Mistakes and Misunderstandings in Place Value

  • Reading numbers right to left.

  • Thinking the digit’s face value is the same as its place value.

  • Misplacing the decimal point.

  • Ignoring zeroes in significant positions.

Tip: Reinforce with real-world examples like money (£2.50) or measurements (3.25 litres).

Teaching Place Value in Primary School

Visual Aids and Manipulatives

  • Base-10 blocks (units, rods, flats)

  • Place value counters

  • Digit cards

  • Number lines

Interactive Games and Activities

  • Place value bingo

  • Roll-a-number challenges

  • Online platforms like Topmarks Maths

Place Value in Real-Life Situations

  • Money: £1.25 = 1 pound and 25 pence

  • Time: 1 hour = 60 minutes = 3,600 seconds

  • Measurement: 1.5 kg = 1,500 g

  • Population figures: 65,000 people = 6 ten thousands + 5 thousands

Conclusion

Place value is the cornerstone of mathematical understanding in primary school. When students grasp this concept, they unlock the ability to work confidently with both whole numbers and decimals. Through clear explanations, hands-on activities, and practical examples, learners can build a strong foundation in maths that will serve them for life. Enrol for affordable Online Tutoring UK

FAQs

Q1: What is place value in simple terms?
Place value tells us how much a digit is worth based on where it is in a number.

Q2: Why do we need place value?
It helps us understand, read, and work with numbers of all sizes.

Q3: What is the difference between place and value?
Place is the digit’s position; value is how much the digit is worth in that place.

Q4: How is zero important in place value?
Zero holds a place to ensure digits are in the correct positions.

Q5: What is expanded form?
It’s a way of writing numbers to show the value of each digit. Example: 4,205 = 4,000 + 200 + 5

Q6: How do you teach place value to struggling learners?
Use visual aids, hands-on tools, and start with small numbers. Repetition and real-life context help.
