These two worksheets look at doubling larger numbers, including those in the teens. It is well worthwhile asking children how they have worked these out in their heads, making use of the knowledge they have. For example doubling 17 can be worked out in several ways:

double 10 and double 7 and add

double 7 and double 10 and add

double 20 and take 6 away

double 15 and add 4.

Children will develop different methods but they do need to be shown that there is more than one way to reach the answer. The ultimate aim is to find a variety of efficient quick methods for calculating.

A couple of speed trials aimed to improve rapid recall of basic addition and subtraction facts. Eventually knowledge of addition of single digits should become second nature – children do not need to work them out, but know them just like they know their name! Subtraction facts can then quickly be worked out from this knowledge.

Two maths worksheets which look at counting on and back in twos. When doing this keep to small numbers until children are really confident moving up and down a number line in twos. Don’t forget you can create your own number lines on a path, driveway etc and jumping up and down in twos can be more exciting than just jumping in ones! Start at different numbers and talk about what is happening eg counting down – with odd numbers you will always end on one, whilst with even numbers you will end on zero. It is also easy to make your own number tracks on paper – with a little imagination move a train along a track or a pirate’s prisoner along the plank! Once again, it can’t be emphasised enough how important it is to play simple board games with your children where they are moving counters along a number track.

By year 5 children are expected to be able to read and write some seriously large numbers. A really good understanding of place value is needed to read large numbers successfully. The key to looking at a number and working out how to say it lies in separating the number up into a series of hundreds, tens and units.

A good understanding of place value is crucial for successful mental arithmetic and progress with written methods of the four rules. The value of a digit depends on its place in the number. For example: the 2 in 1 234 is worth 200 whilst the 2 in 4 321 is worth only 20. Our whole number system is based around this idea but don’t be surprised if your children find it difficult – many do! It seems quite an old fashioned idea to place the letters HTU to stand for hundreds, tens and units, above a number or sum, but it does help with this understanding and in reading numbers out loud.
