Revision of MODAL VERBS

We are back to our lessons again. Last year we learnt the use of modal verbs shall/should/may/might/could/have to/must/ needn't/couldn't to express:

• obligations and prohibitions 
•  duties and necessity
•  future possibilities
•  ask permission
•  ask for and offer help and advice
•  make requests and invitations 

Click on the link to play the snakes and ladders' game to revise.  Remember that modals are never followed by infinitive with "to" , they have no -s/-es for third person singular and never use auxiliaries for negative and interrogative sentences.

On the website from British council you cann practise and learn about rules and examples.Do the exercises below:
