Last day of school...how do we keep kids motivated?

What can we do to keep our students motivated on the last day of school?  I ask myself this question all the time.  I know by the end of the year everyone including administrators need a break from school.  If staff is feeling this way so are the students.

So let's think what would keep us motivated on the last day of school:

• food
• ice-cream
• no work
• activities
• guest speakers
• party
• water fights (weather permitting)
• teacher - student sport game

Getting students to come to school on the last day and be motivated I think applies more to the high schools.  Correct me if I'm wrong.  Therefore, teachers have a hard time already motivating high school students on a regular school day.  So what might it look like on the last day? 

Well let me tell you:

• water fights outside on the field
• skipping classes
• horse playing in the halls
• food fight in the cafeteria
• pulling the fire alarm
• and much much more

Help me, because us teachers need to stick together.  What type of motivating strategies have you used on the last few days of school?
