Question tags

Hello,

I'm looking for interesting ways to present question tags to an upper-intermediate group.

Any ideas for activities will be helpful.

Thank you.

Shouldn't upper-intermediate students be familiar with them?

There's not a lot of amazing and stimulating ideas out there, but you could try these two:

Tag Mix - a straightforward way to practice Question Tags with your class.

Verifying Tags - an activity to practice using question tags.

I often wonder myself about teaching question tags. It seems to be part of most course books but I wonder how much they're really used in everyday English.
