Hi Natasha,
 
A few simple suggestions:
 
* Awards ceremony- You can have a simple awards ceremony.  Give award for best writer, best reader, most improved, best grades, most creative, et cetera.  The award can be a certificate and a special pencil.  Something simple.
 
*Share food- Ask students to bring in a favorite food to share.  If the weather is nice, you can go outside to share it.  This is also a great time to practice saying names of food in English!  :)
 
*Play a game-  Play any game the students like. You can go outside and play soccer for example.
 
*Autograph book- Have each student make a simple book using colored paper.  Ask the students to decorate their book and write their names on the cover.  Then, ask other students to write messages in everybody �s book.  Then, all your students will have a special book to take home with messages from their classmates.
 
*Slide show-  Take pictures of your students with a digital camera.  Show them the pictures on the last day.
 
Hope these ideas get you started!
 
:) Teri
