Speaking as someone who spent his career in IT, I can see a little bit of benefit to teaching kids to "code". Computers will no longer be magic boxes and they can decide if they like doing it. 

But I wouldn't waste a lot of time on it. 

Strangely enough, there are a lot of jobs in IT that require reasonable fluency in English and being able to read and write reports and documents.

And, I should add, a lot of "coding" jobs are disappearing off to places like India. So if your only skill when you finish school is "coding", you may have some difficulty finding a job. And, also, whatever computer language you might be taught in grade 6 will likely be obsolete by the time you finish high school. 

Sorry, but IT has its share of fads too.
