CELTA Pre task

[Unregistered]

Help!!

I am doing pre interview task for the CELTA english teaching course.
I'm having a wee spot of bother with two of the questions.

1.

I am playing tennis every Tuesday.

Correction: I play tennis every Tuesday.

Now I have to explain the correction using terms like " Present progrssive " but the grammar book I have is not much help.

Any advise would be helpfull

Thanks

Shannon
