3rd Grade [session2]

Have to.

• We use have to to talk about strong obligation that comes from somewhere else; for example from you boss, you parents, a rule at school or work.
  
  Examples:
  I have to be home by ten. (My parents told me so.)
  I have to get up early, because I start work at 8. (It is a rule.)
  I have to stop when the traffic light is red. (It is the law.)

• Don't have to means that there isn't any obligation at all,
  there is no need to do it.
  Examples:
  I don't have to get up early at weekend. (I can stay in bed as long as I want.)
  You don't have to go with me. (You can go with me if you want to.)

• We use has to/doesn't have to for 3rd person singular pronouns: he, she & it.
