For this activity, we learned the basics of conducting music.
I went the simple route and used the information from the back of the hymn book. We talked about eighth, quarter, half and whole notes and what they meant while conducting. We tried out a couple of different hymns from the book with various time signatures while one of the girls played the piano. I taught them how to look for the time signature and which beat pattern to use for them.
Some of the girls already had quite a bit of knowledge about music and they were able to assist me in teaching the other girls. It was also a good opportunity for the girls who could play the piano to practice in front of others.
