## Year 2 maths worksheet: counting on in tens

Here we have another page to help with counting on in tens from a 2-digit numbers. A little care needs to be taken with these as the question asks,

“How many tens did you count?”

So, when counting in tens from 23 to 43 the answer is 2 (tens), not twenty.

Many children (and adults) count out loud and use their fingers to work out the answer to this type of question, holding out one finger each time ten more is added. Nothing wrong with this but care needs to be taken that ten is not counted when saying the first number out loud.

## Year 3 maths worksheet: Counting in tens

By year 3 most children are quite confident with counting up in tens, but there can still be some difficulties, especially when counting over a hundreds boundary. This page looks specifically at this, with a set of number tracks which need completing. All of them cross the hundreds boundary and involve both counting on and counting back.

## Resource of the week: counting and colouring fish to total 10.

Our counting game, colouring ten fish, is great practice for young children both with counting and seeing how many ways three small numbers can total 10.

The game involves clicking on each of ten fish to make them change colour. One click changes the fish to red, two clicks turns the fish blue and a third click will make it gold.

Any fish can be coloured as long as the totals work out correctly. Just click on the ‘Go’ button to see if you have completed the colouring correctly… and there’s even a colouring page to print out at the end!

## Maths Worksheet: Count on Whole Hundreds

This worksheet is very similar to the year 4 ‘count on in tens’, but this time it is counting on in whole hundreds. When working these out the tens and units can be ignored as they do not change – just add up the hundreds and write them down with the tens and units.

Most of these questions cross the thousands boundary and provide good practice at reading larger numbers.

## Maths Worksheet: Counting up, crossing thousands

There are many occasions when a 4-digit subtraction can be done ‘in your head’. These questions, suitable for Year 5, are examples of this. They all involve numbers which are just over and just under a whole thousand.

For example: 3003 – 2994

Probably the easiest way to do this mentally is to count on 7 from 2993 to make 3000 and then count on, or add, the extra 4, making 11.

This is much easier than doing the question on paper, with lots of ‘borrowing’ and carrying, crossing out etc!

## Maths Worksheet: Year 4 Count on Whole Tens

This worksheet looks at counting on in whole tens from 3-digit numbers, probably most suited for Year 4 children. There are a number of different strategies that children use to do this type of question. Some will count on in tens (still using fingers to record the number of tens they have counted). Others will use more efficient methods, such as, adding the tens digits and then adjusting the hundreds.

## Year 1 worksheets: Counting up to 20

Here we have a very straightforward couple of pages with up to 20 sweets to count. We work hard with children when they first start to count but then tend to neglect this area of counting on past ten. The sweets have been laid out in such a way that there are rows of ten. ‘Bright sparks’ may spot this and start at ten and just count the second row. ‘Burning hot’ sparks might do a quick subtraction with the rows that are nearly ten: it’s always interesting to watch how children set about tasks such as these.

There’s lots more for young children at urbrainy.com, which is rapidly becoming one of the best sites around for early years maths.

## Year 3 maths worksheet: counting in tens

This free maths worksheet is a development  in counting on in tens as it involves crossing the hundreds boundary. Most children find it easy to count on in tens until the number  becomes more than 100, then a certain amount of confusion can occur. It is a good idea to have a number line which goes across the hundred – of course most of us have a ready made one in the form of a tape measure. (As long as you use the centimetres!)

## Year 1 maths worksheet: counting back 4

Once children have got a firm grasp of working with numbers up to 10 their skills can be developed with addition and subtraction from larger numbers, beginning with teens. This maths worksheet is a first step at counting back 4 from a number, including crossing the ten boundary. The arrows can be used to help count down 4. Continue to encourage counting back ‘out loud’. If children want to use their fingers then the best way is to hold four fingers up and say the number to count down from and then take one finger away each time they count back one until there are no fingers left!

## Year 1 maths worksheet: counting on in tens

Here is a maths worksheet suitable for year 1 children, taken from the great range of maths at urbrainy.com.

When children first learn to count in tens they usually start with whole tens eg 10, 20, 30, 40 etc.

This page takes the concept one step further in that the starting number is not a multiple of 10.

When counting on from 13 children will quickly realise that the units remain the same and that it is the tens digit which is increasing by one  each time.
