I've found four interesting videos related to el Dia de los Muertos and Halloween for the students to compare and contrast.
This activity is ALL IN SPANISH, for an upper-level (Span 3 or 4+) class. I've included links to the YouTube videos and I've also created Tiny URLs and QR codes to help the students find the content.
There are questions for writing after watching the four short films. (Length of films are 8 minutes, 7 minutes, 6.5 minutes and 10 minutes).
The document is in Word, so you can edit it to your liking, or change-out the video links if one does not suit your curriculum.
This would be a good substitute activity if you plan to be gone any time around the end of October or the 1st of November!
