This one is actually a round, but it would work as a chant - or maybe a chant round! (Depending on the age group you're doing it with). The beginning of each line is the first beat of each measure. 'bottle of' is to be done like a triplet. Count quietly *2 3* after POP to provide the necessary rests. 'Fish' is held out for a beat and a half. 'Vinegar' is quick - eighth eighth quarter (rest), rather than three quarter notes.
Hope it works for you! One bottle of pop Two bottles of pop Three bottles of pop four bottles of pop five bottles of pop six bottles of pop seven bottles of pop POP
