What Is Place Value? Explained For Primary Parents And Kids!
In this post we will be explaining what place value is, what it means, and providing you with some questions you can use to test your KS2 child’s skills!
What is place value?
Place value is the value of each digit in a number.
For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000.
It is important that children understand that whilst a digit can be the same, its value depends on where it is in the number.
Children will most likely be taught place value through a place value chart like this…
Often these will just appear with letters on them to represent each position Millions, Hundred Thousands, Ten Thousands, Thousands, Hundreds, Tens, Ones, tenths, hundredths, and so on.
You can download your own place value grid and activity here. It takes no time at all to make and then you can physically manipulate the numbers to show their place value. This makes a real difference when working with children.

When will my child learn about place value in school?
Place value is arguably one of the most important areas of the primary maths curriculum.
Every year group has a set of objectives specifically focused on number and place value. Come September every year in primary school your child is likely to be recapping previous place value work and building on it with larger (or smaller in the case of decimals) numbers.
Examples of these objectives are below:
Place value in Year 1
In Year 1 pupils should:
- Count to and across 100;
- count, read and write numbers to 100 in numerals.
Pupils may also begin to recognise place value in numbers beyond 20 by reading, writing, counting and comparing numbers up to 100, supported by objects and pictorial representations.
Place value in Year 2
In Year 2 pupils should:
- Recognise the place value of each digit in a two-digit number (tens, ones);
- read and write numbers to at least 100 in numerals and in words;
- use place value and number facts to solve problems.
By the end of year 2, pupils should know the number bonds to 20 and be precise in using and understanding place value.
Place value in Year 3
In Year 3 pupils should:
- Recognise the place value of each digit in a three-digit number (hundreds, tens, ones);
- read and write numbers up to 1000 in numerals and in words;
- use larger numbers to at least 1000, applying partitioning related to place value using varied and increasingly complex problems;
- use a variety of representations, including those related to measure;
- continue to count in ones, tens and hundreds, so that they become fluent in the order and place value of numbers to 1000.
Place value in Year 4
In Year 4 pupils should:
- Recognise the place value of each digit in a four-digit number (thousands, hundreds, tens, and ones);
- know that over time, the numeral system changed to include the concept of zero and place value.
Place value in Year 5
In Year 5 pupils should:
- Read, write, order and compare numbers to at least 1 000 000 and determine the value of each digit.
Place value in Year 6
In Year 6 pupils should:
- Read, write, order and compare numbers up to 10 000 000 and determine the value of each digit.
How will my child be taught place value at primary school?
Throughout primary school, two concrete maths resources are used to help make place value easy to understand for children. Both of the following aids do this by representing place value in a visual manner.
Dienes blocks for place value
Dienes blocks are cubes that are used to represent units/ones, tens, hundreds and thousands.
These cubes are a simple way for children make different numbers. To make the number 174, they would need to gather one set of 100, 7 sets of 10 and four single cubes.
Arrow cards for place value
Arrow cards are simple visual representations of hundreds, tens and units that children can manipulate to create different numbers and learn about place value.
Children may be asked to make up numbers to show that they have a firm grasp on place value. For example, if a child was asked to make the number 241, they would place the 40 card over the last two digits on the 200 one, and the 1 card over the last digit on the 40 card.
Understanding place value is crucial for children before they can move on to adding and subtracting two-digit numbers.
If you’re interested in digging deeper into this topic, then we recommend reading this detailed guide to teaching place value at KS2 and trying out some of these place value game and place value worksheets.
How does place value relate to other areas of maths?
Place value is intrinsically linked to many other areas of maths; a solid understanding of place value is vital in order to allow children to competently add, subtract, multiply and divide, amongst other things.
Place value and other areas of maths: A year by year breakdown
In Year 2, recording addition and subtraction in columns supports place value and prepares for formal written methods with larger numbers. Year 2 also connects the 10 multiplication table to place value.
In Year 3 pupils solve problems, including missing number problems, using number facts, place value, and more complex addition and subtraction.
Year 3’s use their understanding of place value and partitioning, and practise using columnar addition and subtraction with increasingly large numbers up to three digits to become fluent.
They will also connect tenths (1/10) to place value.
In Year 4, place value is used in multiplication and division, where known and derived facts are used to multiply and divide mentally.
Year 4 pupils should connect hundredths to tenths and place value. Their understanding of the number system and decimal place value is extended at this stage to tenths and then hundredths. In measurement, Year 4 pupils build on their understanding of place value and decimal notation to record metric measures, including money.
In Year 5 pupils use their knowledge of place value and multiplication and division to convert between standard units, such as metres and kilometres.
Place value practice questions for primary school children
Try these to get an idea of how comfortable your child is with place value.
1) In the following numbers, what is the digit 7 worth? a) 405.7 b) 30,070
2) Jack has four number cards: 2, 3, 4 and 7. He uses each card once to make a four-digit number. He places: 4 in the tens column; 2 so that it has a higher value that any of the other digits; the remaining two digits so that 7 has the higher value. What number did Jack make?
3) Look at this number: 23,451.96. Write the digit that is in the a) hundreds place b) hundredths place.
4) Write the number 402,037 in words.
