Err... sorry I don't know said teacher, I was just following along your comment, where you seem to portray the teacher in such way.

You even do it in this comment, condescendingly,

>I would not expect a kindergarten teacher to be [...] fully educated in other counting methods than base 10

Honestly, it's not that big of a deal to know binary or not.

But anyway, that aside, you completely missed the point of my comment. Whew.

Are you saying that my not expecting a kindergarten teacher to be educated in binary math is condescending?

I got your point that 10 in binary is not actually base 10 10, but 2 in base 10. It was just not worth commenting as it was a discussion about a 5 year old conversation not the semantics of math.

I mean, I'd want my kindergarten teacher to be focused teaching kindergarteners. I don't want them to be an expert on calculus, just be the best teacher for a kindergartener. Same thing as "i want my IDE to focus on being an IDE, and not add facebook integration".

I feel like making sure the absolute fundamentals are well ingrained in your kid is way more important than trying to teach them binary.

Important stuff like learning the alphabet. How to read simple books. Things like that.

That was my point. Expecting a kindergaten teacher to do anything beyond those things you listed is not reasonable. It's great if after teaching a day of kindergartners they can then do an evening teaching college classes, but that's so not the norm. Stating that a teacher at this level is not fully versed in binary is not an insult. It's more insulting to think that someone was able to construe that from my comment.

That was not a condescending comment by my read.

Replace counting in other bases with “theoretical physics” or “woodworking” and it doesn’t read that way either.

I think this xkcd is relevant here: https://xkcd.com/2501/

I was taught how to count in binary in grade 5, is this not a normal thing that kids learn in school?

I think it depends on what curriculum your school's using; non-base-10 math is a punchline in Tom Lehrer's "New Math" [1]. Common Core might be getting rid of it?

As a side note, comparing the complaints in "New Math" (from 1965) to those offered about Common Core is educational :)
