Sadly, it is not just Yanks (though we are on a role of anti-American lately here
). Millennial Australians and current primary and secondary schoolers probably can't. We have had to EXTENSIVELY home-teach (supplemental to regular schooling) our 9 y.o - she was not able to tell me a single Australian capitol until I taught her, let alone name any planets, understand what a year is, or even do division.
What appals me is they get homework once a fortnight, and ONLY if we ask for it!!! WTF!!!!!!!!!!!!!!! Soros education for you! So, we take matters in our own hands - a responsibility that every parent should take since the education system is failing to deliver - our 9y.o went from all C's to now nearly all B's in a matter or a couple months of work. Plus she also attends non-English after-school schooling for 3 hours 5 days a week.
Her younger sister, thankfully, we "rescued" in time after recognising the failings of the sordidly pathetic education system.
