Disclaimer I do TEFL so I am essentially untrained and have to deal with a language barrier . I have a powerpoint . Rule 1 , 2 , and 3 . Rule 1 is be silent when the teacher is talking . Rule 2 is the same . I ask them , what is rule 3 ? They say be quiet or put their fingers on their lips , and I say yes , correct . Then they repeat , rote , as a group , I will be silent while the teacher is talking 35 times . We do that until everyone is saying it , in unison . Then I explain what I want them to not do . Then I explain my system 10 marks on the board . If all 10 remain , everyone gets a sweet . If 5 remain , we will play a music video for 4 minutes at the end of class . If 0 remain , grammar test for the entirety of the next lesson . I tell them , I don ' t want that . Do you want that ? No , teacher . Then we all raise our right arm and sit in silence for 15 seconds , resetting if anyone talks . Max I had to do is 11 resets . I have said We will do this all lesson if we have to . We will do it next lesson too . We will sit in silence for 15 seconds until you get it right . I know you don ' t enjoy it . Do you think I do ? It ' s worked like a charm ! Why ? Because if more than one table ruins it for everyone , no one gets the reward . If one table misbehaves , they get no candy . But . it ' s different here . I ' m sorry if this isn ' t super helpful , but maybe it could give you inspiration ? From one Brit teacher to another , good luck !
