Year 3 maths worksheet: Double 2-digit numbers
Doubling 2-digit numbers can be quite easy or fairly tricky; it all depends on the numbers. For a number such as 23, doubling is easy as the tens and units can be doubled in your head in either order and can be easily remembered.
However, doubling 37 leads to more complex mathematical thinking as at least three separate operations are needed to reach the correct answer. Probably the easiest way is to double the 30 to make 60. Holding 60 in the back of your mind add the 7 to make 67 and then add the 7 again to make 74. Another way is to double the 30 to make 60 and then double the 7 to make 14 and then add the 60 and the 14 to make 74.
There are other ways, including doubling 40 to make 80 and taking 6 away (double 3) to reach 74. It is always a good idea to see how children tackle these types of questions, ask them what they did and see if it is an efficient way.
Year 3 maths worksheets: Subtraction
Many children still need plenty of practice with adding and subtracting small numbers mentally. Here is a nifty way to give practice in subtracting a single digit from a teen in a slightly different way from the usual questions.Suitable for bright year 2 or year 3 children.
The second page shows a blank grid which can be printed out and your own choice of numbers put in – useful for children with particular problems with subtraction.
These pages can be found in our Year 3, Know Number facts section
Year 3 maths worksheet: Make 5 sided shapes
By Year 3 children should be familiar with the names of 5 and 6 sided shapes: pentagons and hexagons. Usually these shapes are seen in a regular form and children do not always recognise them when they are irregular. This mini investigation will help with this. A geoboard is a great help. Schools already have these, but at home it is easy enough to make one – just 9 short nails evenly spaced in a block of wood and some elastic bands are all that is needed.
When doing this it can be quite tricky to recognise two shapes which are the same but just rotated.
Year 3 worksheet: counting in tens
These are a useful couple of pages for children entering Year 3 next term. Counting on and back will still be important in year 3, using up to three digit numbers. Grouping into tens or fives and using tally charts are both effective ways of counting larger numbers.
Children seldom get a chance to count a larger number of objects – somewhere between 30 and 60. By seeing and counting this many they become more able to estimate larger numbers and be able to give rough approximations rather than wild guesses.
Try similar exercises with heaps of coins, counters etc, dividing them up into fives or tens. A really good idea is to collect change (pennies etc) and guess how much of any one coin there is.

Year 3 maths worksheet: Make 12 investigation
Here we have a rather nice number investigation for Year 3. Using exactly 5 of the cards, how many ways can 12 be made?
It is probably a good idea to cut out the cards, or make your own, to make it much easier to move the numbers around to make the number sentences.
As with all investigations look out for a logical, well ordered method, although at the beginning most children will work in a random fashion (as will most adults.) Once it is clear that there are a number of 2-digit subtractions that can be done it is important to show them in some logical way so that it can be seen that all possible combinations have been covered.
Rules can be changed or adapted: one of the first questions which might come up is ‘Can I use the cards twice?’ In the case of adding three single digits the plus sign needs to be used twice, but children can make their own rules for this.
Year 3 maths worksheet: Counting back
This is the second page of revising counting back in whole tens from any 2-digit or 3-digit number. Some children still find this difficult, especially when it involves crossing a hundreds boundary. If children do find this hard it is well worthwhile going back to a large number square and making sure that they are confident with counting on, crossing the hundreds boundary.

Calculator game: 5x table
This is another in our series of using a calculator to help learn and reinforce tables. To be successful with this game you need to know your 5x table: the calculator just confirms your correct mental arithmetic (or not!). This series of calculator activities for 2x, 3x, 5x and 10x tables are all found in the Year 3: Know number facts section.
Counting back in tens: Year 3 revision
In year 3 many children still find it tricky to count on and back and there is a danger that they are moved on to harder maths before they have mastered this basic skill. This is a page which can be used as a check to make sure that they are confident with counting back in tens from any 2 or 3-digit number.
Calculator game: Multiples of 10
Multiples of ten are fairly easy to work out, but nevertheless this is a good game of strategy to play to help reinforce multiples of 10. Choose a number on the grid then try and make it on the calculator by multiplying a number by 10. If correct and the answer on the calculator matches the number on the grid place a coloured counter on the grid. Play then goes to your opponent, with the aim of trying to get 4 in a row.

Year 3 maths worksheet: Reading scales
Children are used to reading scales where the divisions go up in ones, but they find it much harder when either they go up in larger numbers or when not all the divisions are numbered. This worksheet does both of these. The ruler shown is a scale drawing and each division is 10 cm, but only the 100 cm division lines are named.
Once it has been established that each mark represents 10 cm., it is relatively straightforward to work out the lengths shown. As children usually only use centimetre rulers this might be the first time they come across a ruler where not all the divisions are numbered.
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.

Calculator game: Multiples of 5
The idea of this game is to make a row of 4 in any direction before your opponent. Take it in turns to use the calculator to multiple chosen numbers to match numbers on the grid. This is excellent practice at multiplying and dividing by 5 mentally and then using the calculator to check answers. Suitable for year 3 upwards.
