Prezi about Question Tags
It is very common in English conversations to finish the sentences with short questions to show interest. This is called Question Tag.
Question tags are very easy to learn and use, but they have to be explained very clearly at the beginning as well as praccticed to create confidence in the students to learn them.
I found this prezi when I wanted to explained them to my students this years, and although I think it was very good, I included some pictures and examples to make them guess the rules and structure. I also completed it with some exercises because it is very important to practice it.It is a bit long, but it is worth the time, because students understand it very well. Here you have the link, hope you enjoy it:
