Thank you.
It constantly amazes me the things my daughter is learning at a young age. But, in other areas, school seems to be weaker. Like she isn't as fast with her times tables as I was at that age, and her spelling is quite a bit weaker too (at least according to my best memory of what I was like at that age). Maybe they figure that isn't as necessary with calculators and spell checkers everywhere?
But as far as the categories, the kids didn't choose those. They just made up a project, and then the teachers had to figure out what category it fit in.
