Too Cool for School Linky Party

I'm a native Texan which means I'm used to hot weather.  But lately it has been a little unbearable.  We've suffered through 15 consecutive days of triple-digit temperatures.  I'm sorry, but 107 is not ok.

So, it got me thinking...yes, I may be a little delusional due to the heat, but anyway... How about throw a linky party to cool off!?!?!  I want to know the coolest tip, trick, technique, or time-saver that you use in your classroom.  If you want to include more than one cool idea, then feel free to take the plunge.  But just one cool tip is enough.

Here is my cool tip:

• Use a yellow highlighter and write "Original" across any paper that you want to save in your files.  The word "Original" won't show up if you copy the paper, and it reminds you that it's your last copy.

So let the cool party begin!  And it would be really cool if you could follow my blog as you link up.  Feel free to share a link from your blog or share your tip in a comment.  Either way...stay cool!
