MATHS- ARITHMETIC Addition, subtraction,

multiplication and division.

ADDITION AND SUBTRACTION

For addition and subtraction we always use column method

(Unless we can easily spot a number bond)

Make a list of all your number bonds to 10 to help you out.

Don’t forget addition and subtraction go hand-in-hand. Subtraction is the inverse of addition.

This means you can check your answers by doing the opposite.

For example, 23+14= 37 37-14= 23

Have a look on nrich and see if you can solve any of the problems! There are lots of KS2 Addition and Subtraction problems.

MULTIPLICATION AND DIVISION

MULTIPLICATION

In Year 5, we need to be able to multiply two digit numbers by four digit numbers.

Practise multiplying two digits by two digits first and work your way up!

If you are finding it too tricky, start off by multiplying by one digit. The key to this is knowing your times tables. Use TTRockstars to help.

Multiplying by one digit: https://www.twinkl.co.uk/resource/year-3-diving-into-mastery-multiply-2-digits-by-1-digit-1-teaching-pack-t-m-30562

PRACTISE

The easiest way to come up with new questions is to use a dice

(or virtual dice https://www.random.org/dice/)

Simply roll the dice and write the numbers. Multiply them. Use a calculator to check your answers.

44 x 61

MULTIPLYING TWO DIGITS BY TWO DIGITS

Remember our little chant:

Ones x Ones

Ones x Tens

MAGIC ZERO

Tens x Ones

Tens x Tens

ADD THEM UP

https://www.youtube.com/watch?v=zkUUNo90eSE

The chant comes from our

understanding of place value.

(Parents – ones were previously

known as units – it is the same

thing!)

We have had lots of practise

with this in class – so hopefully

you can remember!

Use a calculator to check your

answer.

MULTIPLYING TWO DIGITS BY TWO DIGITS

MULTIPLYING TWO DIGITS BY THREE DIGITSIt is the same method again. But the chant is a little different. Can you work out how? We need to multiply the digit in the hundreds too!

Ones x Ones

Ones x Tens

Ones x Hundreds

MAGIC ZERO

Tens x Ones

Tens x Tens

Tens x Hundreds

ADD THEM UP

MULTIPLYING TWO DIGITS BY THREE DIGITS

MULTIPLYING TWO DIGITS BY FOUR DIGITS The final step – this is the end goal so don’t worry if you find it a little trickier!

I bet you can all do it though! (Growth Mindset guys!) Ones x Ones

Ones x Tens

Ones x Hundreds

Ones x Thousands

MAGIC ZERO

Tens x Ones

Tens x Tens

Tens x Hundreds

Tens x Thousands

ADD THEM UP

You will spot here that you can find these questions

in the Year 6 SATS! How amazing that you are already

ready for this Worth two marks too BUZZING!

Extra GD Challenge:

Can you work out how to multiply a three digit number by a three digit number?

How would the chant change?

How many Magic Zeros would be needed?

Investigate.

DIVISION

DIVISION

Division is the inverse of multiplication. Again, it is really important to know your times tables. If you are not confident with them you will find it much harder.

The formal method of division is the bus stop method.
