Free Y4 maths worksheets: relate addition and subtraction
One of the most important concepts for children to understand in the early years is the relationship between addition and subtraction. Given one set of facts they should be able to deduce several other facts.
For example:
If 40 + 30 = 70 then:
30 + 40 = 70
and
70 – 40 = 30
and
70 – 30 = 40.
These two free worksheets look at this relationship.

Free Y4 Maths worksheets. What must be added?
Both these free worksheets look at questions which involve adding on from one number to make another. In this case they are all adding on from a 3-digit number to the next whole hundred. Again, there is more than one way to do these. As an example look at the question:
“What must be added to 345 to make 400?”
Method 1: add on from 345 to 350 (5) then add 50 to make 350.
Method 2: add on 50 to 345 to make 395 then count on the extra 5.
Plenty of practice still needed at counting up and down in whole tens and as with all mental arithmetic remember to ask your child how they reached the answer as well as seeing whether it is correct or not.
Maths worksheets: Partition into ThHTU Y4
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.

Maths worksheets: Pictograms Year 4
Plenty of progress is expected with data handling during Stage 4. By the end of the year children should have a good understanding of, and be able to spell, these words:
Vote, survey, questionnaire, data, count, tally, sort, set, represent, table, list, graph, chart, diagram, axes, label, title, most common or popular.
One of the most difficult concepts for them is the pictogram. This will be the first time that they come across a symbol which represents more than one item (eg. one stick person represents 10 people). Help is often needed in pointing out that the picture means ten people, not just one and that half a stick person represents 5 people. They should be able to interpret and answer simple questions about pictograms.
Maths worksheets: Y4 Standard units of measurement
The metric system is so easy to understand. Take length for example: no 12 inches in a foot, 3 feet in a yard or 1760 yards in a mile. It’s all tens, hundreds and thousands! By Stage 4 (8/9 yrs old) children should know the standard units of measurement for length, including the abbreviations.
mm (millimetres) cm (centimetres) m (metres) and km (kilometres) . Continue reading “Maths worksheets: Standard units of measurement. Y4”
Maths worksheets Rapid addition and subtraction
Here’s some practice for your children at adding and subtracting multiples of ten. Essentially, they are using their knowledge of addition and subtraction facts to work out harder questions. Knowing that 13 – 7 is 6 makes it easy to work out 130 – 70 = 60, but only if you understand place value! This is good revision for Year 4, and they are fairly straightforward as they do not cross the thousands boundary. If difficulties are found with these then it would be well worth going back to looking at addition and subtraction of single digits. Also, make sure your child can read the numbers correctly. A blank number line could also be very useful.
cube, cuboid, pyramid, sphere, hemisphere, cylinder, cone, prism, tetrahedron and polyhedron
Those tricky 3D shape names! By year 4 children should be familiar with a number of 3D shapes, including,
cube, cuboid, pyramid, sphere, hemisphere, cylinder, cone, prism, tetrahedron and polyhedron.
You can look up these words using an online dictionary such as the MathSphere dictionary or Kids Dictionary for Maths.

Choose the operation and method
One of the hardest things to get children to do is explain how they did a sum. These two pages try to help with this, encouraging them to explain the decisions they make about:
which operation is involved in word problems
whether calculations can be done mentally or with pen and paper
how to explain and record the operations used.
Talking about what they do is vital in the internalisation of processes, which eventually become second nature.
adding three small numbers
When looking at adding three small numbers there are several strategies which can be employed. Usually it is better to start with the largest number, rather than the first number.

Reading four digit numbers
Reading four digit numbers can be tricky. Understanding of place value is vital – realising that each digit becomes ten times bigger when it moves one place to the left. We will return to this many times and in more detail. To begin, this worksheet shows the column names to help with reading the numbers.
