The song is so repetitive and sweet (and appropriate!). So, I wrote up a little story to use with my Spanish 1 students. I also created a basic cloze activity and translated the song. Click here if you would like to use the story or just the cloze activity.
Update 1/25/20: Here is another activity from TeachVid.
Update 9/19/19: I just created this video and made a little evaluacioncita for it for after the story.
