If you are looking for a good Navidad en América Latina resource, check out www.navidadlatina.com. This site has information on how holidays are celebrated in different Spanish-speaking countries, villancicos, videos, games, recipes and more. If you have native speakers or higher levels, you could have them do some sort of webquest and research what traditions are from the different countries. The site used to have an English version, which would be great for level 1’s but they got rid of that 😦
Another resource you may find useful is www.navidaddigital.com. This site has a very large list of villancicos, recipes and pictures of belenes or pesebres to see.
What resources do you use for la Navidad? How would you have your students use these resources?
