Have you been searching for a relevant, fun, real-life way to teach Usted and negative tú commands, as well as direct object pronouns [mete Lola]? Here it is!
I am a sociolinguist, court interpreter/translator, and professor of Spanish, and I L♥VE music! I used this amazing song by Don Omar y Romeo teach commands [sneakily using the subjunctive masked as commands too!] as well as direct object pronouns. **This song has PG-13 content, suggested for older students only!**
The lyrics are publicly accessed, as is the YouTube video link, but its use for second language acquisition is non-infringing and fair use.
