How do you finish off a debate?

Okay so basically debating consists of one topic which can be a statement or question, for an example I'll use the topic "that homework should be banned in school"

you have three speakers and one silent speaker who helps write speeches and rebut arguments, there is the affirmative- they agree with the topic, and the negative- they disagree. the affirmative begins the debate. different speakers have different roles, the 1st speaker of the affirmative introduces the topic, scopes the topic, makes a model if required, and allocates the arguments between themselves and their second speaker, then they go into their arguments. 1st speaker of the negative rebuts the arguments made by the 1st aff. and then goes into their own definition of the topic, scope and sometimes model, they then discuss their points. 2nd speakers rebut and do their arguments and 3rd sums everything up using no new information and half their speech is rebuttle.

that's about it. just arguing for or against a topic but using structure whilst doing so.
