Here is how, with Common Core, the children are required to solve this problem in not TWO steps (90/18), but in 108 steps.
They are required to draw 18 circles, and put 1 hash mark near each circle until they get to circle 18, loop back to the beginning with another hash mark near each circle to the end, and repeat this until they have drawn 90 total hash marks, and then count how many marks are near each circle.
If they do it the simple way (90/18) they fail.
Folks, using hash marks is the cave man way of doing it, and you won't learn ANYTHING doing it that way.
That is how people who know nothing at all about math are forced to do it in totally uneducated regions of the world, IF they are stupid as well as not educated.
This is cold hard proof that our educational system is actually training the kids to think like monkeys. If in the 4th grade your educational level is so low that you are required to hash mark out math, you have no education at all and the requirement of doing it this way or face failure is insurance to the global elite that you will attend school, LEARN NOTHING, and fail if you are taught how to do it the correct way elsewhere and insist on doing it right.
After having this new Common Core method forced on them, fourth graders who got straight A's on internationally standardized math tests in third grade were reduced to C's D's and F's on internationally standardized tests in the fourth grade.
The sabotage is so effective in removing proper mathematical thinking from the children that what is learned in past years is over written and lost.
Common Core is an act of war on America, but we all know who is now in control of our education. And with this "elite" zionist community seeking permanent intellectual dominance over all people, it is easy to see why common core is getting rammed down America's throat.
