Query: Perfect for beginning to read music

These cards have worked out very well for my two sons (ages 11 and 7). We do them a few times a week and they are quickly learning how to read music. We incorporate them with actual playing on the piano. They are excited as they learn the notes to apply their knowledge into playing a song. They do not come with a box, but work out just fine.
