I was that child. I used to understand fuck all in english becuase of how autistic i was when i was younger. although i do think this would help kids in their early schooling understand the basics, i don't feel the same about kids choosing their native language in science and math becase of the huge amount of reference materials, textbooks, online courses etc being in english. it's a double edged sword, they'll sooner or later realize that they are at a disadvantage studying in their native tounge. case in point : my autistic ass
