One of the fun activities that grades 4-8 do in Computers just before Christmas break is called Type that Christmas Tune. It's a great way to practice keyboarding skills and have some fun at the same time. We listen to instrumental versions of various Christmas songs, and the students have to type the name of the song. I use some of the more recognizable songs for the lower grades and use some of the more difficult songs with the older students. After I play 10 different tracks, we go through each one again and name the tune. The student(s) with the most titles correct wins a little prize. I usually get candy cane pens from the local Walgreens for a reasonable price.
This activity could really be done with any kind of music at any time of the year.
