I've tried this C.D. with three different classes P6/7, P3/4/5 and an infant class, and in each one I've had excellent results. The class settled down quickly and worked quietly. It was great to get feedback from the classroom assistants as they too, were really surprised at how quickly the children took to the music and how much calmer they all seemed. I'll continue to use this C.D both in class and at home and a few colleagues are interested in purchasing copies for themselves after having borrowed mine.
