as a person that grew up in an European country I can tell you that beginning with grade 4 or 5 (cant remember exactly), we started learning geography, physics, history, biology, another language... I am not saying that it isnt too much for a child, cause sometimes it was... I remember my mom had to sit with me every night and help me with homework.... anyways in geography, we learned where countries are located, bodies of water, topography, neighbors etc.
