I would think that the play party type “dances” would be good for getting them to equate certain melodies/and perhaps the beat to movement. I second Sasha and others like that. If I were doing this I’d incorporate some drumming but that may not be for you. However, if anyone is interested there’s a ton of resources on YouTube on how to introduce this age group to drumming/percussion. Would it be a good idea to find out what the in tunes are for this age group are and use that music as a starting point? Lastly I hope they are paying you well for your efforts!!!!! Sounds like a real chore. Tom
