Not to ask stupid questions, but if you're leading a "Perl Team", shouldn't you be coming up with the exercises yourself? A quick read through the last couple weeks' worth of posts to Seekers of Perl Wisdom will give you many ideas. Also, what's with the "Each exercise should take at least one day of time to finish"? The whole point of Perl is that it's the fastest language on Earth to write programs in, so assuming you do your job well, the exercises shouldn't take more than an hour or two each for your students to complete. I suggest lots of tiny exercises for references, nested data structures, and regular expressions, with a brief skimming over of the other topics. Nested data structures are probably the most difficult thing to understand as a newbie programmer.
