Honestly it's so difficult to find a map that satisfies all of one's requirements for teaching kids if you're a bit rigorous.

I might be asking bit too much but I want Antarctica to be shown correctly, I want all microstates to be shown, I want all the "(UK)" and "(FR)" mentions for overseas territories to be there, ideally Taipei to be shown as a capital, etc, and that's only what I care about, I'm sure there are dozens of other details I don't think of that are wrong on most maps.

I ended up making my own world map with d3 (that was 10 years ago, I don't know what I would use today) and print it at a print shop. I printed a dymaxion map (with ocean blue for the gaps) and another more "normal" projection though I don't actually remember which one, with Antarctica as an insert. It wasn't even expensive, and in addition I was able to put all the names in both French and Dutch.

You might assume that in Belgium, it would at least be possible to find bilingual maps but no, if you can find one that's not in English you're already lucky.
