One or two years ago when I was watching the Amazing Race on TV, there was an episode where the contestants had to figure out what was the year written in Roman numerals. I found it sad that a lot of them didn't understand what it was.
I am hoping that my children will better appreciate architecture with/and Roman numerals engraved into them.

So, are Roman numerals taught in Singapore Math? If it is, which grade/level? If not, what did you use to teach Roman numerals?
Thanks!
