Maths - Introducing Ratio
A ratio shows you how much of one thing there is compared to another.
The two amounts are written with a colon (:) between them, like this a:b. When saying the ratio out loud, you would usually say, “a to b”.
Watch this video from to learn more about ratios.
The order you write a ratio is really important. You must write the quantity of the object that is mentioned first, followed by the quantity of the second object. If you don’t, the proportions change!
For every apple, there are two oranges.
This statement has compared the amounts of two fruits.
Since apples were mentioned first, you write that amount first, followed by the number of oranges:
apples : oranges
so the correct ratio is
If the amount of apples and oranges changed, the ratio would change.
Now for every three apples, there are four oranges.
The ratio would be written as 3:4.
For every five strawberry ice creams, there are six vanilla ice creams.
Lucy has written the ratio as 6:5. Is she correct?
Oops, Lucy has made a mistake. Instead of writing the ratio as strawberry to vanilla (the order in which the statement says), she has written it as vanilla to strawberry.
The correct ratio would be 5:6.
Sometimes, you might see that a ratio statement can be written in a number of ways - this is a form of simplifying the ratio.
For every eight yellow dots, there are six orange dots.
This would make the ratio 8:6.
However, you could also say:
For every four yellow dots, there are three orange dots.
The ratio would now be 4:3.
You have halved the original amounts on both sides to create a simplified ratio.
Now that you cannot divide either side of the ratio anymore, it is in its simplest form.

English - Creating a Leaflet
Leaflets are used to inform and persuade people about different things.
Watch this video to find out what makes a good leaflet.
When writing a leaflet, it's a good idea to plan first. Leaflets contain lots of information so you need to think carefully before you start writing.
Your layout is important too. Think about:
Your title. It should be bold and catchy to grab the reader’s attention.
The summary. You could use persuasive language and other devices - such as alliteration - to engage the reader.
Using subheadings to organise the text.
Keeping your paragraphs short so the leaflet is easy to read.
Using eye-catching images to help persuade and inform the reader.
Including graphs, charts or maps to share complicated information in an attractive and easy way.
It’s also important to think carefully about the audience for your leaflet (who will read it?) and about your register (how formal or informal does it need to be?).
A useful piece of punctuation to use in any complex writing is a semi-colon.
Watch this video to revise how to use semi-colons.
- Replace a full stop between two related sentences or independent clauses. For example:
I had a huge lunch; however, I am already hungry again.
- Replace a coordinating conjunction. For example:
She missed they penalty and they lost the game can become She missed the penalty; they lost the game.
- Separate items in lists. For example:
Joseph scanned through his list for school: food for lunch; pens for writing; a book to read and and a coat in case it rained.
Do this worksheet on the use of semi-colons.
You are going to create your own leaflet about the pros and cons of reintroducing wild lynx into Great Britain.
Watch the video below to learn all about this topic.
As you watch, you may find it useful to make notes under these headings:
facts about lynx
why people want to reintroduce them
why others don’t want to reintroduce them
the benefits of reintroducing lynx to Great Britain
Now write your leaflet.
Either print out and use the leaflet template, or copy the layout of the template on to some plain paper.
plan before you write
think about layout
include a title, summary and subheadings
keep your paragraphs short
include images, graphs, charts or maps where appropriate
Challenge yourself to use semi-colons in your leaflet. Remember – they can help you to join two related sentences or organise items in a list.
