One thing our kids are learning at Primary School is persuasive language - both spoken and written. How to argue their point and explain their opinions.
This is also something that is in the Naplan tests in the form of a writing test. I've mentioned before this link to Pascal Press which has free downloadable sample writing tests and answers for each graded level.
Here are some topics from those samples, some past tests and some of our own ideas too.

Life is easier today than in the past.
Dogs are a better pet than cats.
Cats are a better pet than dogs.
Every child should have a pet.

Here is a site with some ideas on how to structure an argument.
I hope this gives a few ideas for topics you can bring up with your kids to help them practice arguing their opinions!
