So even though I've been teaching a long time, I never thought of doing this. This year my four 8th grade classes celebrated one girl's Quinceañera in each class. After reading about what is a Quinceañera and doing comparisons with Bat Mitzvah and confirmations, we learned to do a 'vals'.
The kids loved it. Students prepared authentic foods for our Quinceañera and invited other classes. This also was a hit because of the Quinceañera dress! To learn the vals, I searched YouTube videos until we found this one http://youtu.be/ocExyKPUT9w
We made a few adjustments ( no lifts) but all-in-all the students really learned quickly.
