Here is the fifth installment in the Open (Source) English series of materials I've been presenting on this blog. Open Source (I also like to think of it at time as 'open sauce'!) is a very apt name for this sort of material, because you can adapt it at will for your own classroom use but it also works very much from the idea that we are opening the learners (and the learning space itself) as rich sources of potential communicative content and language.
Here's a quick look at the Time Flies edition, why it was made this way and how you might use it.
Here are those open source downloads:
Open English - Time Flies (MS Word 2007)
Open English - Time Flies (Compatible)
Remember there is a variety of other Open Source English resources with accompanying video tutorials/ideas in the Open English section of the blog.
Whether or not time is on your side, hope this helps... :-)
