We are rapidly approaching the Christmas season in schools, with plenty of work going on preparing concerts, nativities etc. but the maths work still needs to go on, so here are a couple of worksheets for Year 1 children with a Christmas feel to them.
They look at counting on in whole tens from any 2-digit number, with answers up to 100. It is important that children are confident and happy with counting in ones up to 100 before starting this and some children may still need a number square to help them with this. Counting on in tens also helps with the understanding of partitioning numbers into tens and units and it is important to ask children what is happening, both to the tens and the units.

The latest draft version of the Primary Maths Programme of Study includes counting to and across 100, which has usually been left until year 2. It is quite tricky and shouldn’t be covered until you are certain that children can count confidently up to 100.
Here is a worksheet aimed at helping with this, counting three, four or five more in steps of one and crossing the hundred boundary in each case. Thanks to urbrainy.com for letting me adapt one of their pages.
Count across one hundred
Counting is one of those activities that it is all to easy to assume that children can do. In fact there are many children in Primary Schools who are very shaky in their knowledge of numbers and counting in ones, forwards or backwards. Yet one of the targets for Year 1 is for children to count on and back in twos and threes. This page is a help towards achieving this as it looks at counting back from a 2-digit number in threes. Starting at 43 count back 1, 2, 3 and reach 40; colour the square and count back a further three and so on. When the end of the line has been reached get children to read the numbers which have been coloured, both forwards and backwards. predictions could also be made as to which number comes next.
A blank sheet has been provided at the end of these pages so that different starting numbers can be used, or children asked to fill in the numbers themselves.
This page can be found in our Year 1 Counting category.
Count down in threes
It is often assumed that children in year 1 are capable at counting, but this is frequently not the case and they need plenty of practice reciting the number names and counting on and back.
Of course number rhymes such as ‘One, two, three, four, five, Once I caught a fish alive’ will help with this.
There are plenty of occasions when counting can be done in a practical situation, such as counting out knives and forks, counting objects, recounting them if they have been rearranged etc.
This worksheet looks at counting sets of objects with numbers up to 20. They balls etc have been arranged so that they do not line up neatly, which makes it harder for them to be counted.
Count up to 20 (2)
A great deal is expected of children by the end of Year 2 and we have some great maths worksheets to help them on their way.
By the end of the year children are expected to read and write 2-digit numbers in figures and words, describe and extend number sequences and recognise odd and even numbers.
They should continue to gain confidence with counting in singe steps up to at least 100 and begin to count in twos, fives and tens. Estimating a number of objects and rounding 2-digit numbers to the nearest ten are also introduced in Year 2.
There are a number of pages on counting on and back in ones and tens, finding missing numbers on number squares as well as recognising simple fractions.

I recently published a page on counting on in steps of 10p which was quite straightforward, but this one is much trickier. This time the counting on crosses the hundreds boundary and in the case of money this also crosses the decimal point.
The first set of questions just looks at 2-digit numbers which cross the hundreds boundary;
For example: 96p + 10p = 106p.
Questions 7 to 10 are much harder as they show the money as pounds rather than pence.
For example: £6.94 + 10p = £7.04.
There is quite a lot to remember here, including putting the pence as .04.
Some children will find this difficult and may well use their fingers to count on in single digits. Others will not convert to pounds properly; often answers such as this are seen:
£6.94 + 10p = £6.104
which shows a lack of understanding of the decimal system.
Count on in 10p crossing hundreds
The fourth, and probably last in a mini series of missing numbers on number grids. Each grid is part of a 1-100 number square with most of the numbers missing. The grid can be tackled in any order and it is interesting to see how confidently children approach this task. Some will be happiest by counting on in ones and filling in what they can before trying to count back in ones. Others will leap in and happily fill the columns in vertically, adding ten each time.
This and other similar pages can be found in the Year 2 Counting category.
Missing numbers on a number square (4)
The third in my series on missing numbers on a number square which can be found in the Year 2 Counting category. Each grid shows a different section from a 1-100 number grid, with only a couple of the numbers filled in. The task is to complete the number grid.
This is very good practice at counting on and back in ones, from any 2-digit starting number. It is also very good at showing the patterns in numbers, for example by moving down the grid one space the number increases by ten.

To attain maths level 1 children need to be able to recognise the number names up to 20, say them clearly and write them. They will be counting forwards and backwards up to 20, starting at any whole number.
To enable this to happen the numerals need to be displayed clearly on a wall so that they can be frequently referred to. Every opportunity needs to be given to count on and back in practical situations, around the home, in the kitchen, at the supermarket, in the car etc. There are lots of games which involve counting and using dice. Number lines and number tracks are really useful; pointing at each number before it is said whilst counting up and down. Eventually the number track can be visualised in a child’s head, helping with fast mental arithmetic.
To herlp with all of this, I have a good selection of worksheets for counting in:
and Year 2 which will help with this process.
We have a great set of worksheets for Counting and Number for year 3. There are pages which require grouping objects in to fives and tens to help with counting. There are also worksheets on counting back in tens, including crossing the hundreds boundary which can be tricky.
We have several worksheets which use number tracks to count as well as some revision exercises for those less confident with counting on and back. Slightly harder are the pages on finding half way between two numbers. A number line is always useful for this kind of work.
