Thousands, hundreds, tens and ones
A four-digit number has four columns: thousands (Th), hundreds (H), tens (T) and ones (O). Each column is worth 10 times the column to its right. 10 ones make 1 ten. 10 tens make 1 hundred. 10 hundreds make 1 thousand.
You can show a number with base-ten blocks. A big cube is 1,000, a flat is 100, a rod is 10 and a small cube is 1. These blocks show 2,314.
You can also use place-value counters. Each counter in a column has the value of that column. Here is 4,306. The tens column has no counters, so the digit there is a 0. The zero is a place holder. It keeps the other digits in the right columns. Without it, 4,306 would look like 436.
Partitioning means splitting a number into the value of each digit: 4,306 = 4,000 + 300 + 6. We write numbers in words too: 4,306 is four thousand, three hundred and six. We put “and” before the last two digits.
Key words. The value of a digit is what it is worth. A digit is one of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. A place holder is a zero that holds an empty column.
Key ideas
- Columns, right to left: ones, tens, hundreds, thousands. Each is 10 times bigger than the one before.
- The value of a digit is the digit times the value of its column: the 7 in 3,742 is worth 700.
- A zero is a place holder: 4,306 and 436 are very different numbers.
- Partition: 4,306 = 4,000 + 300 + 6.
- Words: put “and” before the last two digits.
Key words. The value of a digit is how much it is worth. A place-value table has columns: ones (O), tens (T), hundreds (H), thousands (Th).
Method. The value of a digit depends on its column. Find the column, then work out the digit times the column value.
- Write the number in a place-value table. Each column has its own name and value.
Th H T O 5 2 4 7 - Find which column the digit is in. The coloured digit is 2, in the hundreds column.1 hundred = 100
- Multiply the digit by the value of the column. There are 2 hundreds.2 × 100 = 200
Check. Say it in words: 2 hundreds is two hundred. ✓
Watch out. The digit is 2, but its value is 200. The value depends on where the digit sits.
Key words. To partition a number is to split it into parts, one part for each digit.
Method. Partition means splitting a number into the value of each of its digits.
- Write the number in a place-value table. This shows how many thousands, hundreds, tens and ones there are.
Th H T O 6 3 0 5 - Work out the value of each digit. Digit times the value of its column.6 thousands = 6,000
3 hundreds = 300
0 tens = nothing to write
5 ones = 5 - Leave out the zeros. A zero means that column is empty, so there is nothing to add.
- Write the values as an addition. Start with the biggest value.6,305 = 6,000 + 300 + 5
Check. Add them up: 6,000 + 300 + 5 = 6,305. ✓
Watch out. Write 3,000 for 3 thousands, not just 3. Each part keeps its full value.
Method. Count each kind of block, work out what each kind is worth, then add them up.
- Count the big cubes. A big cube is worth 1,000.1 big cube = 1,000
- Count the flats. A flat is worth 100.4 flats = 400
- Count the rods and the small cubes. A rod is worth 10. A small cube is worth 1.2 rods = 20
3 small cubes = 3 - Add the values. Start with the biggest.1,000 + 400 + 20 + 3 = 1,423
Check. Say it in words: one thousand, four hundred and twenty-three. ✓
Watch out. A flat is 100, not 10. Count each kind of block separately.
Method. Say the number in parts, from the biggest column to the smallest: thousands, then hundreds, then the last two digits.
- Write the number in a place-value table. This helps us see each part.
Th H T O 7 0 3 0 - Say each part in words. Put "thousand" after the thousands and "hundred" after the hundreds.7 thousands → seven thousand
30 (the last two digits) → thirty - Join the parts together. Put "and" before the last part, just before the tens and ones.seven thousand and thirty
Check. Read it out loud. It sounds like 7,030. ✓
Watch out. The words for 4,065 are four thousand and sixty-five. There are no hundreds, so you do not say "hundred".
Method. Listen for the words "thousand" and "hundred". They tell you which column each digit goes in.
- Split the words into parts. Each part belongs to one or two columns.four thousand → 4 in the thousands column
no hundreds are said → 0 in the hundreds column
sixty-five → 6 tens and 5 ones - Write the digits in the place-value table. Write 0 in any column that was not mentioned.
Th H T O 4 0 6 5 - Write the number. 4,065
Check. Say 4,065 in words: four thousand and sixty-five. ✓
Watch out. If no tens or ones are said, those columns are zeros: “six thousand” is 6,000.
Watch out
Do not forget the zero place holder. “Four thousand and sixty-five” is 4,065, not 465 and not 4,650. Also remember that the value of a digit is not the digit itself: in 6,420 the 6 is worth 6,000.Exercise 1B Place value in four-digit numbers
Non-calculatorMethod. Count each kind of block, work out what each kind is worth, then add them up.
- Count the big cubes. A big cube is worth 1,000.2 big cubes = 2,000
- Count the flats. A flat is worth 100.4 flats = 400

5 small cubes = 5 - Add the values. Start with the biggest.2,000 + 400 + 30 + 5 = 2,435
Check. Say it in words: two thousand, four hundred and thirty-five. ✓
Watch out. A flat is 100, not 10. Count each kind of block separately.
Method. Count the counters in each column. Each counter is worth the same as the column it is in.
- Count the counters in each column. No counters in a column means a zero.Th column: 3 counters → 3

- Write the number in a place-value table. Seeing the columns helps.
H T O 5 6 0 - Read the digits up to the tens column. The digits to the left of the tens column are bigger columns. Each of them can be swapped for tens: 10 ones make 1 ten, so 1 hundred is 10 tens.The digits 56, read as one number, tell us there are 56 tens.
- Write the answer. 56 tens
Check. 56 × 10 = 560. ✓
Watch out. Do not just give the digit in that column. In 560 there are 56 tens, not 6 tens.

Th H T O 7 3 0 0 - Read the digits up to the hundreds column. The digits to the left of the hundreds column are bigger columns. Each of them can be swapped for hundreds: 10 tens make 1 hundred, so 1 thousand is 10 hundreds.The digits 73, read as one number, tell us there are 73 hundreds.
- Write the answer. 73 hundreds
Check. 73 × 100 = 7,300. ✓
Watch out. Do not just give the digit in that column. In 7,300 there are 73 hundreds, not 3 hundreds.
Key words. A place holder is a zero that holds an empty column so the other digits stay in the right place.
Method. Put each part into its own column of a place-value table. Write a zero in any column with nothing in it.
- Read the parts: 3 thousands, 7 hundreds, 2 tens and 5 ones. Each part tells us which column it goes in and how many.
- Put each digit in its column. The first part goes in the biggest column.3 thousands → write 3 in the Th column
7 hundreds → write 7 in the H column
2 tens → write 2 in the T column
5 ones → write 5 in the O column - Read the digits across the table.
Th H T O 3 7 2 5
The number is 3,725.
Check. Say it in words: three thousand, seven hundred and twenty-five. It matches the parts. ✓
Watch out. A zero is a place holder. It keeps the other digits in the right columns. 4,065 and 465 are very different numbers!
Method. Find the column the 6 is in, then work out its value.
- Write 6,420 in a place-value table. The 6 is in the first column on the left.
Th H T O 6 4 2 0 - Find the value of the 6. The 6 is in the thousands column, so it is 6 thousands.6 × 1,000 = 6,000
- Answer Mei. No. The 6 is worth 6,000, not 6.
Check. 6,420 = 6,000 + 400 + 20 + 0. The 6 stands for 6,000. ✓
Watch out. The digit and its value are different things. A digit in a bigger column is worth more.
Method. Write what Ravi should have written, then compare it with his number.
- Say the words in parts. “Four thousand” is 4 in the thousands column. “Sixty-five” is 6 tens and 5 ones. No hundreds are said.4 thousands, 0 hundreds, 6 tens, 5 ones
- Write it in a place-value table. The empty hundreds column needs a zero.
Th H T O 4 0 6 5 - Compare with Ravi’s number. Ravi wrote 4,650. That has 6 hundreds and 5 tens.4,650 is four thousand, six hundred and fifty.
He put the 6 and the 5 in the wrong columns.
Check. Say 4,065: four thousand and sixty-five. ✓
Watch out. When you do not hear “hundred”, there are no hundreds, so write 0 in the hundreds column.
Method. Work out each number, then find the one that is different.
- Write each as a four-digit number. Use place value.5,030
5,000 + 30 = 5,030
5 thousands and 3 tens = 5,030
