I’m looking for a children’s primer, a first reader series, and one of the books is called “The Bus Riding Book.” In the book, all of the animals get on the bus, one by one, and then a bee flies in and everyone runs out of the bus. I learned to read using it in 1976 in catholic school in Queens, NY. I believe the publisher was McGraw Hill, colorful drawings inside the book with animals getting on the bus, and the cover may have been soft.
