This book was a children’s early reader book from 70s/80s with scenes from a park (which had a pond in it, I think, and possibly a duck in the pond), classroom, hospital room, etc. In the picture of the classroom, for instance, it said “paint” next to where the paints were, and “chair” next to the chair in the picture. No plot, just labels for items in the pictures. It is *not* a Richard Scarry book (which sometime label individual items as well).
Was it one of the Usborne First Thousand Words books?
Could it possibly be “Let’s Go to School”? See the pictures at this link.

Unfortunately not either of those. Thanks for the ideas, though.
