Here is another song I like to use to teach children when we are learning food.
En el supermercado
En el supermercado se venden muchas frutas: Naranjas, uvas, limones, sandia, melones.
En el supermercado se venden legumbres: Guisantes, papas, cebollas, tomates, lechuga.
En el supermercado se venden comestibles: Harina, queso, azucar, aceite, cafe.
Below you can click on my grandchildren singing so you can hear the tune.
I always am fascinated as I talk about food because the vocabulary is so different in so many places. I learned most of my Spanish in Bogota, Colombia so I use those words, for instance, corn is "choclo" there. No one around here, Texas and mostly Mexicans, would have any idea what I am talking about.
Try teaching the song to your children and let me know how it works.
