In KS2 Maths, you'll have loads of fun with multiplication and division! By Year Six, you'll be a times tables champ and a pro at basic multiplication and division. You'll also get to know cool words like 'multiple', 'factor', and 'product'.

Multiplication and division are super cool because they involve remainders – the bits left over. You'll learn to turn leftovers (remainders) into fractions and decimals. Imagine having 4 cats and 10 treats – you give each cat 2 treats, and you're left with 2 treats! Let's turn that into maths magic: 10 ÷ 4 = 2 r2 or 2.5 or 2^{1}⁄_{2}. Now, test your awesome skills with a fun quiz about multiplication and division!

1.

Which strategy would be best to multiply 53 by 25?

Multiply by 100 then double

Multiply by 4 then 100

Multiply by 100 then divide by 4

Divide by 4 then double

2.

5.87 x 100 = ?

587

5,870

0.587

0.0587

To multiply a number by 100 move the digits 2 places to the left

3.

How could we find an eighth of a number?

Multiply it by 4

Multiply it by 8

Divide it by 8

Divide it by 4

An eighth of a number is the same as saying divide it by 8

4.

2.43 x 10 = ?

2.430

24.3

243

0.243

To multiply a number by 10 move the digits 1 place to the left

5.

Which gives the answer 91?

(6 + 5) x (8 - 3) + 6 =

(6 + 5 x 8) - (3 + 6) =

6 + 5 x (8 - 3) + 6 =

(6 + 5) x 8 - 3 + 6 =

Work out the calculations in brackets first

6.

On a calculator the answer to a division question is 5.25. What fraction is the remainder?

Half

Quarter

Third

Eighth

0.25 is the decimal equivalent of ^{1}⁄_{4}

7.

Which of these methods would result in finding ^{1}⁄_{12}?

Half one third twice

Half one quarter twice

Double one quarter twice

Double one sixth

e.g. ^{1}⁄_{12} of 66. One third is 22, half of 22 is 11, half of 11 is 5.5

8.

Which strategy would be best to multiply 93 by 101?

Multiply by 10 then add 93

Multiply by 100 then add 93

Multiply by 100 then subtract 93

Multiply by 10 then subtract 93

You can use this strategy for other numbers over 100, for example to multiply a number by 107 multiply by 100 and also by 7 then add the 2 results together

9.

What is the best method of multiplying 81 by 99?

Multiply by 100 then subtract 81

Multiply by 10 then add 81

Multiply by 100 then add 81

Multiply by 10 then subtract 81

Multiplying by 100 is much easier than multiplying by 99

10.

What is the best method of multiplying 72 by 15?

Multiply by 10 then halve

Multiply by 10, halve the result, then add the two parts together

Multiply by 10, divide by 5, then add the two numbers

Divide by 10 then double

72 x 10 = 720; half of 720 = 360, so 720 + 360 = 1,080

^{1}⁄_{4}of 1, 25 is^{1}⁄_{4}of 100
