Bonfire Night Worksheets

It’s always nice to have something topical to use as part of the maths curriculum. Today I would like to point you to a page on percentages, linked to the theme of bonfire night, or fireworks, suitable for Year 6 children who are learning about how to work out percentages.

Four different kinds of fireworks are on sale, with 20% off. The questions involve working out how much the boxes cost and how much in the way of savings can be made.

Finding 20% is relatively straightforward if done in two parts:

first find 10% by dividing by 2

find 20% by doubling the answer.

You can find this page in my Year 6, Understanding Number section.

Percentage worksheet for Year 5

Here is the second of our percentages worksheets for Year 5. It is typical of the English that we manage to write per cent in two different ways. Unlike the Americans who use percent we use two words per cent, apart from when we write percentage when we put it altogether.

Anyway, as to the maths: remember that many percentages can be worked out ‘in your head’ by remembering that 10% of an amount is equivalent to dividing the amount by 10. At this stage we will only be dealing with whole tens so it is probably the best approach. Later more complicated percentages will be found by dividing by 100 and multiplying by the percentage.

To find 20% of £350.

Find 10% of £350, which  is £35

If 10% is £35, then 20% will be £35 x 2 = £70.

Percentages (pg 2)

Year 5 maths worksheet: Percentages

A straightforward introduction to finding 10% off multiples of 10p up to a pound. This can be done in two stages:

Firstly: find 10% of the total. As these are all multiples of ten this is straightforward – just divide the amount by 10.

eg 10% of 50p is 5p

Secondly: subtract from the original amount.

50p subtract 5p is 45p.

However, if you have some really nifty mathematicians they might spot that if you multiply the 5(tens) by 9 you get 450p and divide by 10 to get 45p (or simply multiply 5 by 9). This is a case of finding 90% rather than finding 10% and subtracting from 100%. Tricky, eh?

Year 6 Maths Worksheet: Percentages and Fractions

percent_and_fractions_1_large

This worksheet looks at the relationship between fractions, decimal fractions and percentages. This often proves very tricky for many children who fail to grasp that because percentage means ‘out of 100’ it can also be represented as a fraction.

Children should begin to understand that 23% also means 23/100 or 0.23.

later, when trying to work out how to find a percentage of a number it can be done quite easily by multiplying by the decimal fraction. In other words, to find 23% of a number multiply it by 0.23.
