My wife teaches Bilingual middle schoolers (spanish/english). Around 40% of the kid’s Moms are from Mexico.
To get the kids to clean up the classroom she has a small list of school appropriate “Cleaning songs”. She never announces it or tells them to clean up. She just turns the music on 5 minutes before class ends.
All the kids with Mexican moms, pop up and start frantically cleaning. The other kids, after a bit of confusion, follow.
She says “I might as well take advantage of all the Pavlovian training their mothers have done.”
