As I take each animal out of the ziploc bag I say (for example), "This animal eats bugs; It's a ____"
"Frog," M answers as she takes the puzzle piece and puts it in the correct place.
Once all of the pieces are placed, I ask, "Can you hand me the animal that eats bugs?" She gives me the frog, and so on and so forth until all of the pieces are put away.
