Revise the Correct Use of the Apostrophe

The apostrophe to show possession
 
An apostrophe can be used to show that something belongs to or is connected with something else.

For example:
Sam's house
The dog's bone
The company's logo

 
The apostrophe is placed before the 's' when something is connected with one person (singular). However, if there were two dogs or more than one company (plural), the apostrophe would be placed after the 's'.

For example:
The dogs' bones
The companies' logos

 
For words that already end in the letter 's', it is correct to add an apostrophe and an extra 's'.

For example:

Jones's Bakery

Thomas's car.

It's and Its:
 
Be careful with these two words as they can be confusing when it comes to apostrophes.
 
It's is a shortened version of it is.
 
Its is a possessive pronoun and does not have an apostrophe. For example, the owner took his dog for its walk.

One huge tip when using apostrophes to show possession ..... check that the apostrophe works by using a finger to cover the apostrophe  and everything that comes after it. If the apostrophe is in the correct place then you should be left with the name of the owner. 

For example:

In 'the children's school', the apostrophe  is correct because if you cover the apostrophe, you're left with the owner - children. If it had said 'the childrens' school' it would have been wrong because the owner would be childrens - which isn't a word!

Also, in 'James's car' the apostrophe is correct because the owner's name is left if you cover the apostrophe - James. If it had been 'Jame's car' it would be wrong because the owner would be Jame - which isn't a name!

Simple really!

Now it's over to you!
