If you are looking for a simple game for beginners for the holidays, you might be interested in this game.
There are four cards in this PDF. I suggest laminating them if you want to keep them, because home printer ink will smear. The teacher calls out a letter and the students cover it with a bingo token. Students can win by covering all of one color or row. Younger children like to play several short games. Older beginners will want to play “black out” and cover all the ornaments.
If you have a few students in your group who are not beginners, make it more difficult for them. Give them a big staff and let them place a token on the staff note as well as the piano key. I have many big staves on my website you can use. There are always ways to make music games more difficult if you think about it.
I used to have some students who had trouble learning piano keys, no matter what cute little ideas I used at the piano. But once I started playing games like this, they learned the keys very quickly. It is a fact that if something is fun, students learn faster. Maria Montessori showed teachers a long time ago that children learn through play.
