A blown first grade presentation isn't a deal breaker. I'd suggest that her speech needs to be short, so she should focus on just a few slides for the class. Remind her that her teacher will see the longer presentation and the written work. I would email the teacher with a head up, too.
I remember my D2 writing a book for class that they were going to have published, and having terrible time management. Her book was far longer and more complex than anyone else's, but she also exhausted her teacher. They had a deadline to meet so the books could be bound. It caused a pretty big rift between her and the teacher near the end of what had been a good year. Just because our kids are smart doesn't mean they have any sense of time management...
Boy, isn't THAT the truth.
If anything, I'd go further and state outright that there may well be a tendency to learn
horrible time management practices from proscribed assignments/work, which then translates into a kind of waking nightmare on open-ended projects like this. I feel your pain.
Another good reason to rein it in early, though, is that advanced coursework in middle/high school often has these embedded "projects" for independent learning. DD
always did more-more-more-more-more on this stuff. She was chasing peer reviewed literature on altruism when she was 8 and 9, spending time in the local university library stacks, etc. On the other hand, getting her through to the finish line on a huge project was hellish.
I see this one as a scope-and-time-management problem, and it's one where it really is pretty critical to emphasize accurate estimation of one's own ability and time needed, and hope that they get it down by the time they reach post-secondary and beyond.
I still have to step in occasionally with DD15 about this, and she's in college. Mostly, she manages that immense course load just fine, and certainly so academically-- but there are times when she is not protective
enough of her own open blocks of time. Deadly, that "it's fine" impulse, which is usually motivated by a sense of never having been SHORT on time to any appreciable degree.
I think that HG/+ kids in particular need help developing a sense of NEEDING to manage their time well.
