I think it was in October this year that Daniela Tomasi published Treasure Hunt together with her colleague Daniela Becchio in The Machine Goes on. For some unknown reason, I have been lazy to try this activity until now.
I'm still a bit dazed at Daniela's and her friend's imagination to implement this idea: music, vocabulary, reading, listening, almost everything thown in for a fun activity suitable to students of all levels.
Thanks very much, Daniela.
