I incorporate each month a new response chant into my classrooms Pre-K through 6th grade. Usually the response will have something to do with the seasons, holidays or common courtesies.
The response chant has also evolved into a classroom management tool, since after the class has responded, everyone is quiet waiting to hear my next instructions.
The teacher calls out a word, sentence, part of a rhyme, etc. and the students "chant" the appropriate response. The response has been, of course, introduced and practice before.
