                                     Tired? Bored? Hungry? And more miles left to go?
                                         Help pass the time on your trip: play a game!
     Everyone knows that a long bus ride can make even the most exciting field trip seem boring. When the
bus is traveling a long distance to reach the cool field trip destination,it can seem like forever. What about
when you are in the backseat waiting to reach Grandma' s house? The road stretches like a rubber band for
miles and miles. Here's a way to beat the road at its own game. Use what you have around you to play games
with your family and friends. You can have fun while you travel!
                                           Materials=nothing but time & imagination
                    Make Them LOOK
                   License Plate Games
1) ABC Version: 
Try to find license plates that begin with
each letter of the alphabet. You can work
together or competitively. Set a time limit
for best results.
2) State Version
Try to find a license plate from every state.
Work as a team. Use paper to keep track of
which ones you have seen if you can,
because 50 states can be hard to keep track
of!
* Note: Feel free to add or change rules.
For example, Alaska and Hawaii plates are
not necessary because those states might
be too far away. You want the game to be
fun, not annoying! 		                   Make Them LAUGH
                          Straight Face
One person is "it". They have to answer
any question with a silly phrase. You
decide what this phrase is before
beginning. A common first phrase is "The
cat's tail." Then you each ask this person a
question, like "What is the most important
thing to take to school tomorrow?" Each
person must ask a question until the person
who is "it" breaks down and laughs or
smiles. Then you pick another phrase.
Some suggested phrases:
＊My horse's hat
＊The bird's boots
