Divide children into small groups and ask them to visualize, that they are doctors working in magic hospital where laziness, cunnings, greediness, anger etc. are being treated.
Children should choose one bad quality and make up a recipe and recommendations how to help people to get rid of this quality.
The recipe from laziness:
Every day from the morning one should take on an empty stomach a drink from orange and several drops of an elixir of diligence. Then, after breakfast, one should stretch onerself a couple of times, then say in a loud voice about everything, what it is necessary to do for this day. And at night it is necessary to write down everything what is made, and to make the plan for the next day. Then it is necessary to drink a glass of milk with several mint sweets for a good dream.
All children's' recipes and recommendations should be compiled into a book: "Magic hospital".
Suggest children to describe, what qualities should have the doctors in this "Magic hospital".
