It's such fun getting a postcard! Students are given a sample postcard, which they can use as a model. They can cut out the blank postcard, make a drawing on the other side about their holiday (they could do the drawing for homework), and imagine they´re still there. The names of the students are written on small slips of paper and put in a box or cap, from which students can pick one - make sure they don't have their own names. They write the postcard to the classmate they´ve chosen. Then the teacher delivers the postcards. It can be done as a back-to-school activity.
