10x table maths worksheet from mathsblog.co.uk

The 10 times table is often the second that is learnt by children, usually after the two times table. The reason for this is that it appears to be easy. Before attempting to learn the table children should have had plenty of practice counting up and down in tens.

However, there is a great danger with the ten times table in that many children are told to just ‘add a nought’ when multiplying by 10. This is disastrous to later understanding of place value and does not work when multiplying a decimal by 10 (eg 2.3 x 10 is not 2.30, it is 23).

The whole idea of tables is that they are learnt, off by heart. To do this it is essential to say them out loud:

One times ten is ten
two times ten is twenty
three times ten is thirty
four times ten is forty
five times ten is fifty
six times ten is sixty
seven times ten is seventy
eight times ten is eighty
nine times ten is ninety
ten times ten is one hundred.

Below are two free maths worksheets on the 10x table.

Here is another in our series of simple, single digit addition. This time there are two worksheets for adding 6 to a single digit.

These pages can act as ‘brain training’ exercises, to help children get to know the number bonds from one to ten so that they can answer from memory. Knowing off by heart all the additions of numbers from 1 to 10 is a great help with rapid mental arithmetic later.

3 x table maths worksheets from mathsblog.co.uk

The 3 times table is one of the harder tables to learn – the pattern of even numbers found in the two times table is not there: but answers do alternate between odd and even. It is usually learned after the twos, tens and fives.
A good way of checking if an answer is correct is to see if the digits add up to 3, 6 or 9. eg 24: 2 + 4 = 6
Remember the danger is that some children are taught that they only need to count up the answers: 3, 6, 9, 12 etc. However, this is not very helpful if a child needs to know what 3 x 9 is; they do not want to have to go through the whole counting up in threes 9 times to get the answer. The whole idea of tables is that they are learnt, off by heart. To do this it is essential to say them out loud:

One times three is three
two times three is six
three times three is nine
four times three is twelve
five times three is fifteen
six times three is eighteen
seven times three is twenty one
eight times three is twenty four
nine times three is twenty seven
ten times three is thirty
Below are two worksheets for the three times table. A good way to do these is to time them to see how long your child takes.

The 2 times table is usually the first that is learnt by children, usually after a lot of practice with doubling small numbers. There is a danger when only using the two times table that children think of multiplying only as ‘timesing by 2’ or doubling.
Another danger is that some children are taught that they only need to count up the answers: 2, 4, 6, 8 etc. However, this is not very helpful if a child needs to know what 2 x 9 is; they do not want to have to go through the whole counting up in twos 9 times to get the answer. The whole idea of tables is that they are learnt, off  by heart. To do this it is essential to say them out loud: Continue reading “Maths worksheet: 2 times table”

Free maths worksheet from mathsblog.co.uk

Here is a worksheet which looks at multiplying a 2-digit number by 2. It uses a method taught in school prior to children using the standard written method, with which you are probably familiar.

This method of multiplication encourages understanding of the process of multiplying a 2-digit number by  a 1-digit number. The questions on this page would not normally be completed using written methods: mental methods should suffice. It would be expected that children could do these ‘in their heads’ from a  knowledge of doubling. However, carrying out the calculation with numbers that they are familiar with should help with understanding the method.

Many parents say that the methods used today for adding are not the same as when they were at school. Often this is not strictly true: the final standard written method is the same, but the steps used to reach this standard method have changed. The worksheet attached explains this in more detail.

The method of addition encourages understanding of the process of adding two, 2-digit numbers. It is known as ‘adding the least significant digit first’.

The method is to add the units first, then add the tens, finally adding the two together. It is a ‘half-way house’towards the standard written method, explaining what happens when the tens boundary is crossed during adding the units (ie when the units add up to more than 10). At this stage ‘carrying’ does not need to take place.

Here are another two worksheets for early subtracting. They concentrate on subtracting a single digit from 10 and use the conventional signs for subtract and equals. At first children will probably ‘add on’ from the lower number to 10. Eventually it will be important that children know all the pairs of numbers that add up to 10 so that they can answer these immediately without going through the ‘add on’process.

adding 2 to a single digit

A couple of free maths worksheets for very simple addition sums here. Aimed at young children who have learnt to count to ten and can begin to add two single digits without the help of a number line. If they find these hard don’t be afraid to use a number line to help.

Here is another in our series of simple addition of single digits, keeping below 10. At first children will count on, probably using their fingers or apparatus such as cubes. In time they need to be able to remember the answers off by heart – but this takes an awful lot of practice.
