Mental Arithmetic 1

Can you multiply 23 x 6 in your head? 

You can make it easier by doing two multiplication sums,

23 x 6 is the same as 20 x 6 and 3 x 6 

                     This gives 120 and 18

               The answer is  120 +  18 = 138

Mental Arithmetic 2

Look at these number facts:

5 x 4 = 20        20/5 = 4

                        20/4 = 5

Mental Arithmetic 3

Look at your multiplication table.

Find the number 24. It appears twice.

We can get 24 by using 4 and 6 as well as by using 3 and 8

4 x 6 = 24   24/6 = 4   3 x 8 = 24  24/8 = 3

                 24/4 = 6                     24/3 = 8

We have four division facts for 24

Decimals 1

Decimal Point - The word decimal comes from the Romans' word for 10.

Our number system is based on 10.

The point marks where whole numbers end and fractions or parts of numbers begin.

Examples of numbers with decimal points are 2.8  3.145  14.08

Decimals 2

Decimals in words - 2.35 in words is two point three five.

 £4.76 in words is four pounds seventy-six. We really mean four pounds and seventy-six pence.
