The document describes a classroom activity to teach children the vocabulary of fruits and vegetables. The teacher divides the class into two groups and has volunteers from each group sit with their backs to the board. The teacher will show a picture of a fruit or vegetable on the board, and the volunteers must describe it to their group without using the word itself. The first group to guess the word correctly earns a point, and the group with the most points after 15 minutes wins. The document provides examples of the language the teacher and pupils might use during the activity.
