a) The teacher and the students analyze crossword puzzles together, either in the first language or the second language, and discuss the procedures or “recipe” to create a crossword puzzle themselves.
b) Following this method, the students create their own crosswords and exchange them among each other to solve the puzzles.
Hint: crossword puzzles based on the Latin alphabet can be easily created, using suitable tools available on the internet. Example: see http://www.xwords-generator.de or: http://www.armoredpenguin.com/crossword
