Year 4: 3, 4, 6, 8 and 10 times tables

How well are tables known? Here is a quick sheet to see how well the 3x, 4x, 6x, 8x and 10 times tables are known. Probably the two hardest of these are the 6 times and 8 times tables and whilst it is well worth knowing that the six times table is double the 3x table and that the 8x table is double the 4x table, there is nothing to beat actually knowing all tables off by heart, so that any answer can be given just as quickly as answering the question ‘What is your name?’

Children who know their tables well will find this page very easy. If they don’t know them it can take a surprisingly long time!

Calculator game: Multiples of 4

multiples of 4_larger_numbersOnce children have learned the 4 times table this calculator game can be played. Set up the calculator to be a 4 times table machine by pressing 4 x x = 0 and then all you have to do to multiply a number by 4 is to type the number and press equals (don’t delete the answer before pressing the next number). Choose a number on the grid and say it out loud, then try and make that number by entering a number on the calculator and multiplying it by 4 by pressing =. If correct place a counter on the grid. Continue taking in turns with the aim of getting 4 in a row.

Complicated? Why not try the game and see just how easy it is.

Year 4 Calculations: Multiplication with words

Here we have the second page which looks at the vocabulary used for multiplication questions. This can used as a quick check to see how well the language is understood as well as how well tables are known. Terms such as ‘lots of’, ‘multiply by’, ‘times’, ‘multiplied by’ are all important to know.

This can be found in our year 4 Calculations section but there are also a lot of other multiplication pages in our Four Rules section.

Year 4 maths worksheet: Multiplication and addition

Here is another in our series of multiplication and addition, suitable for Year 4 upwards.

The rule is that multiplication should be worked out before the addition and in most of these questions that is fairly straightforward. However the questions towards the end are quite tricky.

Let’s look at 70 + ?? x 4 = 150

The best way to go about this is to go in reverse order; subtract 70 from 150 which leaves 80.

Then work out what number multiplied by 4 makes 80, which is 20.

Therefore the missing number is 20.

It is best to check this by going back to the original question; multiply 20 by 4 = 80 and then add 80 and 70 = 150, making the statement true.

Many children will find these very difficult to work out as they require several steps.

Year 4 calculations: Multiplication with words

By year 4 it is expected that children have a pretty good knowledge of their tables, but, of course, they also need to know when multiplication is the correct option. This depends on having a good understanding of the vocabulary involved. Continue reading “Year 4 calculations: Multiplication with words”

Year 4 maths worksheet: Doubling and halving

It’s always a good idea to think about how we work out answers in our heads and doubling multiples of 5 is a good example of this. Thinking and saying what you do is similar to watching  a slow motion movie, in real time everything happens very quickly but by slowing it down each step can be seen in turn.

Let’s look at doubling 65. I know without thinking that double 5 is 10, so I ignore this part and first work out double 60. This is 120. I then add on 10 for the double 5 part, making 130.

A similar process can be used with halving a number such as 130. I take 10 off to make 120 as it is easy to work out half of 120, which is 60. I then add on 5 (which is half of the 10 I took off at the start) making 65.

Try to get children to explain how they do these doubling and halving questions.

Year 4 maths worksheet: Division with remainders

Here is another page where the remainders from division are written as fractions. Children need a good knowledge of tables to work out the division ‘in their heads’ and this is probably best suited to Year 4, aged8/9+ years old.

The remainder goes on the top line (numerator) and the bottom number (denominator) is the number you have divided by.

This is a much neater finish to the question as the whole number is divided completely, with no messy remainders. Some of the fractions could be cancelled down to their simplest form, although this is not essential at this stage.

Year 4 Maths: Multiplication and addition

This is the second worksheet which looks at multiplication and addition. The rule is that the multiplication should be worked out before the addition, whatever the order of the question.

This is a good mental arithmetic exercise but children may need to jot down the answer to the first part (multiplication) before moving on to the addition.

Year 4 maths worksheet: Multiplying by 10 or 100

Remember the golden rules about multiplying:

When a number is multiplied by 10 it moves one place to the left.

When a number is multiplied by 100 it moves two places to the left. if this leaves a gap in the units or tens and units a zero must be inserted as a ‘place holder’.

Don’t get dragged into saying ‘add a nought’ because this doesn’t work with decimals eg 1.5 x 10 is not 1.50!!

Multiply by 10 or 100

Subtract a single digit from a multiple of 100

A nice little revision exercise to check that children are confident with counting across the hundreds boundary and also have quick mental arithmetic strategies.

These questions are all subtracting a single digit from a multiple of 100. Some children will do them by counting back, others will employ different strategies such as subtracting 10 and adjusting. Generally, we are looking for quick and accurate methods.

The last three questions ask children to write down the method they usedm, which can reveal a lot.
