How should I try to give a lecture for more than ten minutes when applying for a primary school music teacher?

You can make students like you as much as possible during the trial lecture time of 10 minute, without teaching too much, mainly to show your cohesion, because children like you and are willing to learn from you, so there is no need to talk too much in this 10 minute, mainly to make students like you and are willing to learn from you. I think this is enough to explain the problem. Personal thoughts. . Hey, hey, good luck! ~
