We moved to Australia and Ds1 is 15 and in Y10 doing extra history subject, so he has double history if you want.
They do historical topics, not historical facts, so for WWII it will be prisoners of war, but not how Hitler got to power in the first place.
They went from Ancient greek to Middle Ages society skipping completely the Roman Empire which makes no sense as how can you understand the rise of the Church without the Fall of the Roman Empire .
They teach bits and bites, no logical order.
I show my sons movies, documentaries, give them books. DS1 is currently reading the Kindly Ones. When he was younger, around 12, I gave him the fall of the giant, as it was a soft introduction to historical fiction. I can't stand young adult crap books. There are great books set in specific historical times that can catch a teen's interest. Michener, roots, .....
DS2 is in Y6. He wouldn't know anything about the birth of writing and therefor history, the Sumerians, or even the Homo Erectus, homo sapiens, the fire, how we became the dominant species, if it wasn;t for books provided at home.
And talking about Geography, the school covers topics such as globalisation, feeding the population, water issues, not countries, capitals, mountains and rivers.
So I think parents need to step in and fill the many holes. Which is not always easy because you compete with Netflix or the PS4.
For all of you, there is an animation movie about Anne Franck. I showed it to my kids when the youngest was 6. There is no scary part, it finishes with the van she is in driving away and birds flying.
It is called Anne no Nikki.
And of course, there are a fair amount of documentaries on Netflix. Just type History in the search box.
