JURASSIC PARK TAG
Choose one person to be the Tyrannosaurus Rex and give that person a red
nerf ball.  This dinosaur eats meat but has bad eyesight.  If a "person" is
standing still they can not be tagged by the T-Rex.  This dinosaur may only
tag their prey.  Choose one person to be a Diloposaurus.  This dinosaur spits!!  Give this dinosaur a different colored ball.  They may throw the ball and hit a
"person" below the shoulders.  They have good eye-sight so if their prey is standing still they can "get" them.
Choose 2-3 people (I found 3 was too difficult) and give them each a
colored ball different from the others.  These are the Vilocoraptors.  They hunt in twos or in packs.  They can only tag their prey together at the same time.
They eventually (especially the older ones) figure out they have to corner
their prey or follow the T-Rex around and wait for their prey to stand
still.  The younger ones will hold hands but that does not work.
If you are tagged by any meat eating dinosaur you freeze.
Choose another person and give them a scooter board.  This is a
Brontosaurus or Tricerotops or any plant eating dinosaur.  They do not eat the "people" and will unfreeze those who have been frozen.  You may want to have 2 in the lower classes cuz they are slow.  I stop them after several minutes and ask:  who has not been tagged, I ask the Vilocoraptors if they caught anyone and if they did, how did they do it, and then I ask the Tricerotops did anyone say thank you to them.  This is a pet peeve with me.  I stress being polite and say please and thank you in my class.
I usually play the game until everyone has had a turn being some dinosaur.
This is one game they all like, even the 5th graders.  The kids will know
the dinosaurs and a discussion will come up about different dinosaurs and their characteristics!!!  Cool, huh?
