1. Try some of the oldies e.g. "A Sailor went to Sea"
A sailor went to sea, sea, sea,
To see what he could see, see, see.
But all that he could see, see, see
Was the bottom of the deep blue sea, sea, sea
2. Make up short, easy rhymes with your students OR use well-known rhymes.
Make up a clapping pattern.
3. Notate the clapping pattern. Either notate just the rhythm on a single line, or use multiline staff to indicate various timbre (hands together, hands tapped on sides, hands clapped on knees, hand claps with partner, etc.)
