10 graders: Possessive Case

This week we will look into the possessive case in English. 

We use the possessive case ('s or ') to express that something belongs to someone. 

Let's look at the rules:

1 - With plural nouns, we add: '
      e.g. The scientists' theory.

2 - With words without the final s, we add: 's
      e.g. The teeth's colour.  Tim's work.

3- With 2 or more names, we add 's to the last name we write. 
     e.g. Tim, Brenda and Alan's grandmother.

4 - With people's names which end in "s" we add: 's
      e.g. Charles's bike.   Inês's car.
