Can you match the decimals to the percentages? When you have completed if you found it difficult refresh your screen and you will get different questions.

See how much money you can win on this addictive game! To calculate the probability each time work out first how many card are left and put this number on the bottom of the fraction. Then work out how many cards that haven’t been turned over yet are higher or lower than the last card. Put this number on the top.Sometimes you will be certain that the next card is higher or lower because all the cards that are higher have already been turned over. If you are certain then it is worth wagering all the money. If the probability is nearer to a half only gamble a small amount of money. This way you should soon become rich!

Note this is an American video- in the UK the middle of the circle is spelt CENTRE. Do sing along!

A factor is a number that divides into another number without a remainder. So the factors of 15 are 1, 3, 5 and 15.

The multiples of 4 are all the numbers in the 4 times table. 4,8,12,16,20,24,28,32……..

A prime number is special because it only has 2 factors. These two factors are always 1 and the number itself. So 7 is a prime number because the factors of 7 are 1 and 7.
