A comment on U.S. math scores drop on major international test. Parent comment
Generally in the US it is:
* K ~5 yo
* 1st ~6 yo
* 2nd ~7 yo
* 3rd ~8 yo
* 4th ~9 yo
* 5th ~10 yos
Give or take of course since birthdays don't align perfectly.
That seems to roughly align to US standards for the same age but not the same grade.
