I found some plastic chocolate bunnies at Easter that I bought to use with storytimes on chocolate. As we were kidding around, I came up with the following rhyme:
Five chocolate bunnies that we adore,
Anna ate one and then there were four.
Four chocolate bunnies yummy to see,
Billy ate one and then there were three.
Three chocolate bunnies delicious it's true,
Sue ate one and then there were two.
Two chocolate bunnies wished they could run,
Scott ate one and then there was one.
One chocolate bunny, only one thing to be done,
I ate it and then there were none.
This can also be done as a flannelboard with felt pieces.
