 Place Value | KS2 Maths Revision | Primary Maths

Understanding place value is important for helping us read and write numbers, and also giving us an idea of just how big a number really is.

There are a lot of words to learn, so it can be helpful to look at this topic using a place value chart.

When finding the value of a digit in a number, we just need to imagine (or find) which column it would be in if we wrote the number in the place value chart.

What is the value of the 3 in 2365?

We start by writing the 5 next to the decimal point and then writing the rest of the numbers to the left.

When finding the value of a digit in a number, we just need to imagine (or find) which column it would be in if we wrote the number in the place value chart.

What is the value of the 3 in 2365?

We start by writing the 5 next to the decimal point and then writing the rest of the numbers to the left.

We can now see that the 3 is in the hundreds column, so must be worth $3\times100=300$.

Luckily, it doesn’t get much more difficult than that, you just need to remember the names of the place values!

There is quite a lot to learn here, but luckily we have you covered:

Example

What is the value of the 2 in 325?

We’d count along twice, which is the tens, so the 2 is worth $2\times10=20$

Example

What is the value of the 4 in 4311?

We’d count along four times, which is the thousands, so the 4 is worth $4\times1,000=4,000$

Example

What is the value of the 7 in 273,400?

We’d count along five times, which is the ten thousands, so the 7 is worth $7\times10,000=70,000$

Example

What is the value of the 1 in 13,000,412?

We’d count along 8 times, which is the ten millions, so the 1 is worth $1\times10,000,000=1,000,000$

Example

What is the value of the 9 in 23.789?

This in the third decimal place, which is the thousandths, so the 9 is worth $19\0.001=0.009$

## Example Questions The 6 is in the hundreds column, so is worth $6\times100=600$. The 8 is in the millions column, so is worth

$8\times1,000,000=8,000,000$. The 7 is in the hundredths column, so is worth $7\times0.01=0.07$.
