Definitely a pain if you're trying to teach it in a sentence-diagramming kind of way. That said, I kind of wonder why you'd be bothering to do that unless the kids are literally not able to understand what's being said and you need to work through it from first principles. (Which I guess is possible? That all reads as a bit of a ramble but perfectly understandable, particularly if you read it out loud.)

For my part, I've never once in my academic career had to explicitly identify sentence parts.
