This rhyme can be found in A History of Nursery Rhymes (1899) by Percy B. Green. Green wrote that it's… "a verse repeated when playing at skimming shells or stones on the water of a pond or lake."

Notes

*A drake is a male duck.

Here's the version from The Real Mother Goose (1916):

A duck and a drake,
And a halfpenny cake,
With a penny to pay the old baker.
A hop and a scotch
Is another notch,
Slitherum, slatherum, take her.
