How to Add 10 to a Number

Adding 10 to 43 using a flipchart

To add 10 to a number, increase the digit in the tens column by 1.

The tens column is the second column from the right.

Leave all other digits the same.

The digit of ‘4’ in 43 increases by 1 to become ‘5’.

43 + 10 = 53.

How to Add 100 to a Number

Adding 100 to the number 841 using a place value flipchart

To add 100 to a number, increase the digit in the hundreds column by 1.

The hundreds column is the third column from the right.

Leave all other digits the same.

The digit of ‘8’ in 841 increases by 1 to become ‘9’.

841 + 100 = 941.

To add 10 to a number, increase the tens column digit by 1.

To add 100 to a number, increase the hundreds column digit by 1

Adding 100 using a place value flipchart example of 3951 + 100 = 4051

We are adding 100 to the number 3951.

We increase the digit in the hundreds column by 1.

9 is the largest digit on our flipchart.

So we instead think of 3951 as having ’39’ hundreds.

We increase ’39’ hundreds by 1 to get ’40’ hundreds.

3951 + 100 – 4051.

Adding 10 and 100

How to Add 10 to a Number

To add 10 to a number, increase the tens digit by 1 and keep all other digits the same. If the tens digit is a 9, then change the 9 to a 0 and increase the hundreds digit by 1.

For example, here is 43. The tens digit is the digit that is second from the right. The tens digit of 43 is ‘4’.

To add 10 to 43, we increase the tens digit by 1.

4 + 1 = 5 and so, the tens digit increases from 4 to 5.

Adding 10 to 43 on a flipchart

43 + 10 = 53.

In this example, we are adding 10 to 18.

We increase the tens digit by 1.

The tens digit of 18 is ‘1’.

Adding 10 to 18 using a place value flipchart

1 + 1 = 2 and so, 18 + 10 = 28.

We can see in these examples that when adding 10, we only changed the tens digit. All other digits in the number remained the same.

This is true when adding 10 to larger numbers too.

Here is 457 + 10.

The tens digit is ‘5’, so we increase 5 to 6.

Adding 10 to a 3 digit number using a flipchart

457 + 10 = 467

We can see that both the digits of ‘4’ and ‘7’ remained the same.

We need to be more careful when adding ten to a number is when the tens digit is a 9.

Here is an example of 92 + 10.

example of adding 10 to 92 to make 102

We currently have a ‘9’ in the tens column. We can increase 9 by 1 to make 10.

We now have 10 tens. To write this, the 9 becomes a 0 and we put a 1 in the hundreds column.

This is because ten tens are one hundred.

In this next example, we have 195 + 10.

Again, we have a ‘9’ in the tens column. We can think of 195 as having ’19’ tens and 5 ones.

We increase 19 by 1 to make 20 tens.

Adding 10 to 195 to make 205

The 19 becomes 20 tens and the 5 ones remain the same.

195 + 10 = 205

We can see that if the digit in the tens column is a 9, then to add 10, we change the 9 to a 0 and increase the hundreds column by 1 instead.

How to Add 100 to a Number

To add 100 to a number, increase the hundreds digit by 1. If the hundreds digit is a 9, then change the 9 to a 0 and increase the thousands digit by 1 instead.

Here is a place value flipchart showing 28. We will count up in hundreds by adding 100 each time. To add 100, we increase the digit in the hundreds column by 1.

Adding 100 using a place value flipchart

Starting with 28, we have 0 hundreds.

We increase this to 128 by adding 100.

Each time 100 is added, we increase the digit in the hundreds column until we reach 928.

To add 100 to 928, we change the 9 to a 0 and increase the thousands digit by 1.

The thousands digit increases from 0 to 1.

928 + 100 = 1028

It is easiest to think of 928 as having 9 hundreds and after adding 100, 1028 has 10 hundreds.

Here is an example of finding 100 more than a number.

To find 100 more than a number, simply increase the digit in the hundreds column by 1.

We want to find one hundred more than 106. 106 has a ‘1’ in the hundreds column.

Adding 100 to the number 106 using a place value flipchart

We increase the ‘1’ in 106 to a ‘2’.

106 + 100 = 206

206 is one hundred more than 106.

To find one hundred more than a number, we must add 1 to the hundreds digit but keep all other digits the same.

In this example we are finding 100 more than 1548.

‘5’ is the hundreds digit.

Adding 100 to a number in the thousands

We increase the ‘5’ to a ‘6’ but keep all other digits the same.

1548 + 100 = 1648

We can see that the digits of ‘1’, ‘4’ and ‘8’ in the other place value columns remained the same.

We need to be more careful when finding 100 more than a number that has a digit of 9 in the hundreds column.

In this example we are adding 100 to 970, which has a 9 in the hundreds column.

We increase the 9 to a 10.

However, to write 10, we change the 9 into a 0 and put a 1 in the next column along.

How to find 100 more than a number example

970 + 100 = 1070

Here is another example of finding 100 more than a number that has a 9 in the hundreds column.

We have 3951.

Because the hundreds column digit is a 9, we change the 9 to a 0 and increase the thousands column digit by 1.

3951 + 100 = 4051

Adding 100 to a number using a flipchart

We can think of the number 3951 as having ’39’ hundreds.

When we add 1 to 39, we get 40.

The answer of 4051 has 40 hundreds and so, we have still increased by 1 hundred.

How to Teach 10 More than a Number

To teach 10 more than a number, it is best to use a place value flipchart. Practise with a variety of different numbers, showing how the tens digit increases by 1 each time 10 is added.

Here is a link to our free interactive place value flipchart for practising finding 10 more than a number.

It is helpful to teach adding 10 by starting with a small number and cycling through the digits. You should say each number as you add ten and change the digit, getting your child to say the number as well.

It is sensible to teach counting up in ones before teaching counting up in tens. It is helpful to familiarise the child with the flipchart by first counting up in ones.

Here we start with 6 on the flipchart. We keep adding 10 to find ten more than the previous number.

The pattern should become clear.

teaching 10 more than a number using a flipchart

Here we start with the number 1.

We add 10 by increasing the tens digit of the flipchart.

Adding 10 when teaching using a flipchart

We can also teach finding 10 more than a number using a number grid.

To find 10 more than a number, simply move one place down on the grid.

For example, here we start with 32 and add 10 to find the number that is 10 more.

42 is directly below 32 and so, it is 10 more.

adding 10 using a number grid

It is helpful to use a variety of methods to teach each concept and both the flipchart and number grid can be used to teach finding 10 more than a number.

The 12 times table is:

1 × 12 = 12

2 × 12 = 24.

3 × 12 = 36

4 × 12 = 48

5 × 12 = 60

11 × 12 = 132

12 × 12 = 144

12 multiplied by 6

The 12 times table is made by counting up in twelves.

To multiply a number by 12, we can multiply the number by 10 and 2 before adding these results.

Multiplying a whole number by 10 just involves putting a zero on the end.

Multiplying a number by 2 just involves adding it to itself.

6 × 10 = 60 and 6 × 2 = 12.

60 + 12 = 72 and so, 6 × 12 = 72.

To multiply a number by 12, multiply it by 10 and 2 then add these results together.

12 multiplied by 5

Here is 5 × 12.

To multiply a number by 12, we multiply by 10 and 2 then add the results together.

How to Memorise the 12 Times Table

The 12 times table is one of the most difficult times tables to memorise because there are not many patterns and the numbers are relatively large.

The first four numbers in the 12 times table can be memorised since the answers are found by multiplying the digits of 1 and 2 in 12 separately.

For example in 2 × 12, we can simply multiply each digit in 12 by 2.

We multiply the 1 and 2 in 12 by 2.

2 × 1 = 2 and 2 × 2 = 4. Therefore 2 × 12 = 24.

12 multiplied by 2

Similarly, to find 3 × 12, we multiply the 1 and 2 in 12 by 3.

3 × 1 = 3 and 3 × 2 = 6. Therefore 3 × 12 = 36.

12 multiplied by 3

Again to find 4 × 12, we multiply the 1 and 2 in 12 by 4.

4 × 1 = 4 and 4 × 2 = 8. Therefore 4 × 12 = 48.

12 multiplied by 4

The same is true for 1 × 12.

1 × 1 = 1 and 1 × 2 = 2. Therefore 1 × 12 = 12.

However it is easiest to just remember that any number multiplied by 1 does not change. 12 remains as 12 when it is multiplied by 1.

12 times 1

This 12 times table trick only works for the first four numbers in the twelve times table.

This is summarised in the table below.

12 Times Table trick

One of the easiest numbers in the twelve times table to remember is 10 × 12 = 120.

This is because to multiply a whole number by 10, we simply put a zero on the end.

Putting a zero on the end of 12 gives us 120.

12 multiplied by 10

For the rest of the 12 times table there are no real easy tricks or patterns. It can be easiest to work out the 12 times table using the following rule:

To multiply by 12, multiply by 10 and 2 and add them together.

This rule is useful because 10 and 2 are relatively easy to multiply by.

We will use this times table rule to work out some numbers in the 12 times table.

For example, here is 5 × 12.

We multiply by 10 and 2 before adding these results together.

5 × 10 = 50 and 5 × 2 = 10.

We add these results to find 5 × 12.

50 + 10 = 60 and so, 5 × 12 = 60.

12 multiplied by 5

Here is 6 × 12.

We multiply by 10 and 2 ten add the results together.

6 × 10 = 60 and 6 × 2 = 12.

60 + 12 = 72 and so, 6 × 12 = 72.

12 multiplied by 6

Here is 7 × 12.

7 × 10 = 70 and 7 × 2 = 14.

70 + 14 = 84 and so, 7 × 12 = 84.

12 multiplied by 7

Here is 8 × 12.

8 ×10 = 80 and 8 × 2 = 16.

80 + 16 = 96 and so, 8 × 12 = 96.

12 multiplied by 8

In this example we have 9 × 12.

9 × 10 = 90 and 9 × 2 = 18.

90 + 18 = 108 and so, 9 × 12 = 108.

12 multiplied by 9

It is best to practice these calculations until the answers become familiar and the 12 times table is memorised off by heart.

10 × 11 = 110

11 × 11 = 121

12 × 11 = 132

11 Times Table chart

The 11 times table is made by counting up in elevens.

To multiply a number from 1 to 9 by 11, simply repeat the digit.

We can remember 11 × 11 = 121 and 12 × 11 = 132 because the outer digits of each answer add up to make the middle digit.

To multiply a single digit number by 11, simply repeat the digit.

11 multiplied by 7

Here is 7 × 11.

To multiply by 11, we simply repeat the digit.

11 Times Table Trick

The times table trick for multiplying a single digit by 11 is to repeat the digit.

For example, to multiply 5 by 11, repeat the digit of 5. Therefore 5 multiplied by 11 is 55.

Here is the 11 times table chart showing this times table trick.

We repeat each digit from 1 to 9 when multiplying them by 11.

11 Times Table trick

Here are some examples of using this times table trick to multiply single digit numbers by 11.

The rule is to multiply single digit numbers by 11, repeat the digit.

Here is the example of 2 × 11 = 22.

We simply repeat the digit of 2 to get 22.

11 multiplied by 2

In this example we multiply 5 by 11.

We repeat the digit of 5 so that 5 × 11 = 55.

11 multiplied by 5

In this example we multiply 7 by 11.

We repeat the digit 7 so that 7 × 11 = 77.

11 multiplied by 7

To remember the remaining numbers in the 11 times table, we can use some further tricks.

To multiply a whole number by 10, we simply put a zero digit on the end.

So 10 × 11 = 110.

11 × 11 = 121 and 12 × 11 = 132.

We can use another trick to remember the answers to 10, 11 and 12 times 11.

All three of these answers begin with 1, end in the same digit as 10, 11 or 12 and the middle digit is the sum of the two outer digits.

For example 10 × 11 = 110.

11 multiplied by 10

110 ends in a 0 like 10 does. 110 starts with a 1 and the middle digit is the sum of these outer digits, 1 and 0.

11 × 11 = 121.

11 multiplied by 12

121 ends in a 1 like 11 does. 121 starts with a 1 and the middle digit is the sum of these outer digits, 1 + 1.

12 × 11 = 132.

11 multiplied by 12

132 ends in a 2 like 2 does. 132 starts with a 2 and the middle digit is the sum of these outer digits, 1 + 2.

8 Times Table chart

How to Learn the 8 Times Table

To learn the 8 times table, remember that the numbers end in the repeating pattern of 8, 6, 4, 2 and 0.

We can group the 8 times table chart into rows of five to see this times table pattern more easily.

8 Times Table pattern on the times table chart

If we know a number in the 8 times table, we can figure out the next number along using this pattern. For example, if we know that 2 × 8 = 16, then we can figure out 3 × 8. 16 ends in 6 and the next number in the pattern 8, 6, 4, 2, 0 after 6 is 4. Therefore 3 × 8 ends in a 4. 3 × 8 = 24.

Apart from going from 5 × 8 = 40 to 6 × 8 = 48 and going from 10 × 8 = 80 to 11 × 8 = 88, all other numbers in the 8 times table increase their tens digit from one number to the next.

So if we remember that 8 × 8 = 64, then we can figure out 9 × 8. Firstly, 64 ends in a 4 and the next number in the pattern of 8, 6, 4, 2, 0 after 4 is a 2. This means that 9 × 8 ends in a 2. We also know that 64 starts with a 6 and so 9 × 8 starts with the number after 6, which is 7. Therefore 9 × 8 = 72.

We simply add eight to get from one number in the 8 times table to the next. One easy way to do this is to add 10 and then subtract 2.

Another pattern can be seen in the 8 times table when it is arranged into rows of five.

8 Times Table trick

The eight times table trick is that when multiplying 8 by a number from 1 to 5, the answer starts with a digit that is one less than the number 1 to 5. When multiplying 8 by a number from 6 to 10, the answer starts with a digit that is two less than the number from 6 to 10. When multiplying 8 by 11 or 12, the answer starts with a digit that is three less than either 11 or 12.

By arranging the 8 times table chart into rows of five, we can see this pattern in the columns.

The numbers in the first column start with a digit that is 1 less than the number we are multiplying by.

The numbers in the second column start with a digit that is 2 less than the number we are multiplying by.

The numbers in the third column start with a digit that is 3 less than the number we are multiplying by.

Whilst it is best to learn the eight times table by heart, this trick can be a useful starting point for remembering the times table when first learning it. It can be a useful prompt for a child first learning the 8 times table.

Examples of the 8 Times Table

The eight times table is one of the more challenging times tables to learn because the numbers are relatively large compared with other times tables. There are some simple tricks to learning the 9, 10 and 11 times table and so, the 8 times table is one of the larger times tables without an easy pattern.

To remember the 8 times table it helps to link it with tricks found in the other times tables. Therefore we recommend that you learn the 8 times table after some of the other times tables have been mastered, or in conjunction with other times tables. This is because learning one times table reinforces another.

We can start with 2 × 8 = 16.

The 2 times table should be one of the first times tables learnt because it involves doubling.

To double, we simply add a number to itself.

8 multiplied by 2

8 + 8 = 16 and so, 2 × 8 = 16.

Next we can learn 10 × 8 = 80 using the ten times table.

8 multiplied by 10

To multiply a whole number by 10, we simply put a zero on the end and so, 10 × 8 = 80.

We can find 11 × 8 = 88 because to multiply a single digit number by 11 simply repeat the digit.

We repeat the digit 8.

8 Times eleven

If we know that 10 × 8 = 80, we can easily find 5 × 8 by halving this answer.

Half of 80 is 40.

Therefore if 10 × 8 = 80,then 5 × 8 = 40.

8 multiplied by 5

To multiply a single digit number by 9, we can subtract one from this number to see what the answer starts with. We then know that the digits of the answer must add to make 9.

So to multiply 8 by 9, subtract 1 from 8 to see that it starts with a 7.

7 + 2 = 9 and so, 9 × 8 = 72.

8 multiplied by 9

There is a trick for multiplying the even digits of 2, 4, 6 and 8 by 6. This means that we can remember 6 × 8.

We write down the even digit being multiplied by 6 as the units digit of the answer. We then halve this digit to find the tens digit that the answer starts with.

8 is the units digit and half of 8 is 4, which is the tens digit.

8 multiplied by 6

6 × 8 = 48.

Finally, multiplying numbers by 12 can be more challenging due to the larger numbers involved.

It can help to multiply the number by 10 and then by 2 before adding these results together.

10 × 8 = 80 and 2 × 8 = 16.

Multiplying by 10 and 2 is relatively easy using the tricks seen above.

We then add 80 + 16 to get 96.

8 multiplied by 12

12 × 8 = 96.

These tricks can help us remember the 8 times table a bit more fluently.

Because 8 is made up of 2 × 2 × 2, we can use another trick of doubling, doubling and doubling again to multiply a number by 8.

For example to work out 3 × 8, we double 3, double the result and double this result again.

3 × 2 = 6 and 6 × 2 = 12 and 12 × 2 = 24.

Therefore 3 × 8 = 24.

Now try our lesson on Multiplying by 4 and 8 by Doubling where we learn how to use doubling to multiply by 4 or 8.

12 × 6 = 72

Pattern in the 6 Times Table

The six times table is made by counting up in sixes.

The numbers repeat the pattern of ending in 6, 2, 8, 4 and 0.

We can work out the next number in the six times table by adding a 6 to the previous number.

When multiplying one of the numbers 2, 4, 6 or 8 by 6, the answer will end in this number and the tens digit will be half of this number.

When multiplying one of the numbers 3, 5, 7, or 9 by 6, the answer ends in 5 more or less than this number.

The 6 times table repeats the pattern of ending in 6, 2, 8, 4 and 0.

6 Times Table trick for multiplying 6 by 8

To multiply the numbers 2, 4, 6, or 8 by 6, there is a simple times table trick we can use.

The answer ends in the same digit. We are multiplying 6 by 8, so our answer ends in an 8.

The tens digit is half of this.

Half of 8 is 4 and so, the tens digit is 4.

8 × 6 = 48.

This trick only works when multiplying six by the numbers 2, 4, 6 or 8.
