Remember my K math problem?

About the silent partners? I totally get it now.

I volunteered in DS's class last week. The teacher was putting flash cards up on the board that had 10 boxes and dots in some of the boxes. The kids had to tell her how the number of dots and how they came up with the number.

For example one kid said 3 plus 3 is 6. Another kid said 2 plus 4 is 6. Then the teacher asked them to do it backward- how many silent partners are there? 4. 10 boxes and 4 are empty so 10-4= 6.

Ok, I had to read that several times and I "think" I get it.

Were they ten frames?

We have had several different uses of words in 1st grade math this year. It's like either call it subtraction/addition or give parents a list of terminology, because this is not stated this way in real life. We figured them all out, but for fun presented them to adults with enigineering degrees thru masters degrees and none of them knew off the bat what info those problems were seeking.

Like what terms? 

It doesn't really matter if adults w/ engineering degree don't know the terms. in 30 years when these kids are those engineers I'm sure they'll be fine.

Well, that I totally agree with. But that is a teacher/homework concern not a concern about how math is done or the terms, you know? You shouldn't have to teach during homework.

That makes sense.

I ways hate the whole "an engineer with a master's degree couldn't do this". When I took an education class about teaching math, our professor had us do simple problems in base 7, base 13, base 4, etc, always mixing it up so we couldn't get used to it. It mimicked the way a young child thinks about numbers without the familiarity adults have with base 10. And let me tell you, those problems were 100x easier using "new math" than they were with the way we were taught. The new math is much more logical and cleaner, we just aren't used to it so it seems overly complicated.
