Maravilloso Mexico is one of my favorites to teach as it incorporates music, art, history and small group work all into one lesson.
This is a great lesson for the Christmas season, if you want to teach about other cultures and how they celebrate the holiday as well as engage your class to dig deeper, discovering why traditions and rituals exist and why they are important.
The lesson begins with music (maybe a little dancing) followed by short lecture into traditions, holidays and cultural context. They then work in small groups to develop new traditions then follow up with a traditional Mexican art piece that they are sure to keep through holidays to come.
