On the right, three desks and chairs should be placed in a row.
On the left, three chairs and desks should be put in a row.the affirmative team should be seated on the left,and the negative team should be seated on the right.
-------------------
Would you check the passage? Correct any errors, please. Thank you. Do you have some more common expressions?

Answer 1

You have the word "debate" three times in the first three sentences. You should delete "over the debate."

Space and capital T is needed in the last section. See it? Also there needs to be a space after the comma in that same sentence. (I know the spaces, capitals and punctuation won't be heard by your audience, but still ... !)

In addition to affirmative and negative, you can also use pros and cons.

(The pros team should be seated on the left,and the cons team should be seated on the right.)

- Thank you for your help. This is the corrected one.-

Answer 3

The only other thing I'd do, to remove repetition, is to omit these words: "on your chairs" (because you know they won't sit on their desks!!).

Otherwise, it all reads really well!
