My 10 year daughter loves legos but complained the other day it seems only boys play legos. I would argue that legos and building things for fun is STEM, and it's curious why girls aren't encouraged to play with legos as much as boys in the U.S. This is despite things like lego friends that are targeting younger girls. Once they hit around 10-11, then all the legos seem to be engineering oriented (robotics etc..), which she loves but can't understand why other girls don't get it.

Note: Am Indian and can totally see the same problem you noted.
