Hell, if this shit sticks our kids wont need to worry about taking any damn iq test. they will be so messed up they will probably turn to drugs to escape trying to solve one of these problems lol
Why are we doing this?

I developed a modified system of math adding, subtracting and percentages when I worked in system implementation of MRP systems on mainframes in the mid seventies. Part of my major responsibility was inventory control, capacity planning and forecasting. I could look at stacks of random parts in different count boxes and do the math in my head without using a calculator. It was very similar to this common core method of bundling the thousands and hundreds and tens. So as an example there would be 10 boxes of 1 inch stainless steel balls and I would have counts ranging in the three digit hundreds....eg....362....498.....740... 245...etc, and in my head I would go 4 down 38, 9 down 40, 17 down zero, 19 down 55 for an answer instantaneously of 1,845, and as a mental exercise I would often reverse the method and add, but still rapidly doing the same in my head. When the Borg Warner outside auditors would come in they would question me on a count on a shelf of parts during an inventory, and thought I was full of chit when I glanced at the same and never used a calculator and gave them an answer. One auditor thought I had memorized certain shelving units to impress him.....which I thought was really weird because I was using a simple technique very similar to what they are trying to teach kids now. He thought I was really smart when in fact I was using a tool which allowed a person without the capacity he probably had to outperform him and his calculator. It was hard to explain, but it certainly had nothing to do with intelligence. It was a perfect example of a person using a tool to expand their capacity beyond their God given talent.

Bob....this confirms you spent way too much time at PB in high school, and not enough time in math class.......the box interfering with the symbol makes no difference.

Common core is but isn't adopted in Florida. It was going into full effect next year, but has met with pushback. There's a lot of parent discontent with it. As it should be. Why have all these steps to add or subtract? It's asinine.:)There's a lot of discontent going on all over the country about this common core crap.
Call me old fashioned and regressive if you must, but really messing with something as simple as subtraction and making it this long process is just another way to confuse kids and further harm future generations. Not to mention the damn parents wont be able to help with homework lol
I'm glad I only have the one left in school and hes in private school and they don't use common core.
Also, on this from my understanding is they don't actually have to get stuff right, just understand the "theory".
oat, when did your wife retire? Did they introduce common core before she retired and did she see it? I think PD has expressed dislike for it if I recall correctly.
It's the admin at district level specifically or in the asst supers office for each level. Principals, believe it or not, are still led by the carrot and stick from the county office.2seaoat wrote:I think my wife and Pace would agree 100% on this subject.

Are you defending common core math?

2+ 4 (the 4 used to round up to 40, the 2 that was included in the first calculation) = 6
40+6=46

Anyhow, that's how my head does it. If was hard to figure out how to put it down on paper! Big blocks, little blocks. Just gotta know how to stack'em.

You know what--I understand how you think that way! I do simple math in my head similarly. But if it gets to be large numbers, forget it!
