Somebody needs to inform OpenAI how Kindergarten works... classes are normally smaller than that, and I don't think any kindergarten teacher would ever try to pull off a "50-minute lesson."
Maybe ai wrote this list of examples. Seems like a hallucination where it just picked wrong numbers.
OpenAI is a California based company. That's about right for a class here
The average kindergarten class size in the US is 22 with rural averages being about 18 and urban averages being 24. While specifics about the distribution is not available, it's not too much of a stretch to think that some kindergarten classes in urban areas would have 25 students.
This varies a lot by location. In my area, that's a normal classroom size. My sister is a kindergarten teacher with 27 students.
I've been to jelly fish rooms in other aquariums that are dark with only glowing jelly fish swimming all around. Pretty sure at least a few toddlers have been entranced by the same.
