I find that when I buy musical concept posters from a teachers store or catalogue they are so 'busy' with information it is hard for my ESL/ELL students to process. I created these super simple concept cards to focus my music teaching concepts. I ask them:
"What are we learning to day?
What did we learn today?" (or in Spanish)
¿Lo que estamos aprendiendo al día?
¿Qué hemos aprendido hoy?
and they look at the Concept Card and can answer the question.
