1. Model
This is a  really simple,effective and communicative
lesson for vocabulary reinforcement. The most
important thing is to choose a good or "essential "
set of words.

* First,  write the list on the right on the board.

*  Ask for the definitions of one of the words and
    write it up.

Then throw the students into groups (I like threes)
and tell them to write their own definitions. Encourage them to be as creative as they like.

2. Speaking
F ood -
       Vocabulary lesson

       Now you have 6 or 7 sets  of meanings for the one set of words.
This is great material for  a  vocabulary reinforcement exercise.   One student from each group stands up with  his or her groups list of definitions and  walks around the other pairs seated eliciting  the vocab by reading  his/her group's meanings.
Because the definitions are different  and some words are close in meaning
this is not as easy as it may seem.

For example:

  Student A: This is something you ask for in a restaurant.
  
  Student B:  "Service"
  
  Student A:  No.
 
  Student C: " A dish"

  Student  A: No.

  Student B: "A menu!"

  Student  A:  Correct.
