I do that when I’m computing large numbers. It does make it easier at times to do that, so it’s not totally worthless.
However, it’s probably too early to introduce that sort of mathematical principle. You can’t teach algebraic principles to,kids who are still learning basic math.
Ok, we get it, union teachers. You suck at math, so you concocted a way to teach something you aren’t strong at. Nevermind, this entire system thinks you don’t know implicitly what 7 plus 7 is, but by gawd, you reliably know that 3 plus 4 equals 7! And that of course, you’re supposed to choose 3 plus 4 so you can add the 3 to the 7 to get 10!
In review, 7 plus 7 hard, but knowing 7 plus 3 is easy. Oh, and 3 plus 4 was easy too.
You know that, and I know that, but all the "education experts" don't know that.
Common Core has been created primarily by two groups, really, really big business, like GE and Microsoft and the Association of Governors. It’s implementation is by the Dept of Education. It is designed solely to provide governors with a docile electorate that does what they are told and for big business, happy docile worker bees, aka serfs.
Big businesses like microsoft and GE will have company schools where their engineers and upper level management will send their kids, free of common core but instead teaching a classical education, but one free of Creation and The Creator. Thus giving big business a pool of company schooled engineers and management.
It is Common Core that has Maine’s secession movement going from super slow to emergency overdrive. Ten years from now there will be no way possible to enforce our Constitutional right to secede since the Common Core voters will out number us by 3 to 1.
Folks Common Core is a much bigger threat to the Republic than anything coming out of Washington in the past 150 years.
If you are a Christian give prayerful thought to moving your family to Maine and helping to create the Free and independent Christian nation of the Republic of Maine.
Common Core was not developed by teachers, it was developed by big business and the governors association. It is a copyrighted and patented program that can not be gotten out of by the 377 states that took Race to the Top money.
Why does anyone think CC is a good idea?
My daughter is going to the community college and has several students in her chemistry class who are taking remedial math and they just graduated high school. Americans are not getting a good education now and it will only get worse.
It kinda makes a person wonder whose “friend” the developers were.
What the hell are “skip count” “number bonds” “making ten” “adding to the ones?”
I used skip math...
7 + 7 = 1+1+1+1+1+1+1+1+1+1+1+1+1+1=10 fingers + 4 toes
“You can’t teach algebraic principles to,kids who are still learning basic math.”
But maybe you can teach them that there is more than one way to solve a problem....heck, it worked for Gauss and summations :-)
Remember that what we are looking at here is just a very easy example being used to illustrate a larger concept. So, of course it looks a little silly. But I wish I had been taught more along these lines rather than just memorize, memorize and memorize.
As for what the appropriate age is for this sort of thing...I admit that I have no idea :-)
I bet there are a lot of teachers asking the same thing. Imagine parents trying to help their kids with homework these days.
I also do that (in my head) but I do NOT call it: “using number bonds to help skip-count by seven by making tens or adding to the ones”.
That phrase is nonsense: both mathematically and linguistically.

No comment necessary, other than this was from the ‘60s.
Old math didn’t work.
That’s why Albert Einstein was never able to work out his theorums for light, time, space and energy.
That’s why men weren’t able to send other men to land on the moon and return to earth 45 yyears ago using just slide rules and their brains.
You can still see guys like this every day on the “Stupid White Guy” commercials on TV.
If only they had known the new “new math”.....

What in the world is wrong, or so difficult, as learning the multiplication tables, or “i” before “e”? I wasn’t an Einstein in math but I learned then and still automatically use the multiplication tables most every day of my life. I’d hate to think I had to use some convoluted, non-sensical method as I see in the extant example. I’m not aiming my comments at you in particular but this math method is asinine and pure crap.
I saw another example on FR last week. I showed it to an engineer and a college math student and neither of them understood the principle behind it or even how to do it.
You can only really learn the short cuts when you’ve mastered the topic. Using shortcuts before that inhibits the learning process because you have no way to verify if your shortcut is a valid one because you cannot compare with the longer method.
It’s like trying to use a shortcut to drive through an unfamiliar city. That short cut might work, but you won’t know it without having known the longer way first.
Certainly not the friend of children in the public schools, nor the Christian and other private schools that are embracing it.
JBS has put out an excellent DVD entitled Common Core ot runs about 70 minutes and is probably the most concise and accurate video available to parents, including Home School parents, concerning the dangers and direction of the common core curriculum.
