Reading fluency or card game?

Reading fluency or Card Game?!?!  At first glance, I could not tell what was going on with this group of 2nd grade boys having so much fun during Language Arts class.  One screamed out a word that they read from a card in their hand while the others frantically looked for the same word in their own hand.  Turns out it was a phonics activity.  It's amazing that their literacy learning included so many laughs!
