Helpful Activity

I really like a dynamic class. Some activities that I like is when the teacher ask everybody to make a circle with the chairs, one chairs less than the number of the students and some of the students have to say a sentence using specific grammar. All the another students stand up or not if they have been lived this situation or not, the last person to seat down should be the next one to say the sentence. It is a helpful activity because we practice our grammar and learn by our classmates errors.
