This is a GREAT activity for someone who is a non-musician that has to sub in a music room. This can keep students busy for 30-40 minutes talking about music terms and symbols and singing and clapping rhythms. I've used it many times for kids from grade 1-5 and they have a great time. I have had subs use it in my absence, and they have had rave reviews! This is level 2, so a little harder than the first one that I created.
