My site is thinking of adding homework functionality (so you can send activity sheets to your students). So to get the ball rolling, I’ve released 10 activity sheets for download (with answer keys), 5 for the present perfect simple, and 5 for the present simple. You can download them off my blog (link in my signature).
All feedback very welcome!
