How do I clue the reader into the fact that this IS a counterargument:

Question

On the contrary, homework lets the parents know what is actually going on in school and keep track of their students progress in school.

Answer 1

One way to clue the reader into the fact that this is a counterargument is to use a contrasting phrase or transitional word, such as "on the contrary," "however," or "despite this." In this particular sentence, the phrase "On the contrary" signals that the statement will present a contrasting viewpoint to the argument previously mentioned.
