If I was taught that method as a kid.... What are they thinking? I can do mental math because I'm able to line the numbers in my head like
no way I'd be able to do that if I had learned that method. I know how to reason, but really I think should be taught in highschool even college not 3rd grade. I hated 3rd grade math, but I would have hated it more even someone didn't tell me how to work a problem then told me to do it and when I got it wrong marked it wrong, knowing that I would not know. Also I don't like the set in stone rule, I understand kids need to learn rules for math, but if it's a word problem and the kid solves it unconventially and the solution and the work makes sense shouldn't they get credit?
These new methods are completely ridiculous. They are time consuming and mentally exhausting. Wtf is a cluster anyways? If you want to teach kids how to cluster mentally, it should be taught after the standard algorithm is. It is no wonder that the average level of intelligence in America's schools is taking a downward plunge. Those books do not teach math, and all should be burned at once.
Btw, the woman in the video writes her 8's funny.

The lattice method is certainly different... very visual in an Ne appealing way. It doesn't explain why it works though. Nor is transition between that and the normal method easy.
But you have to admit that the Turc cluster method IS rather silly. Guess and test is the slowest and least preferred method of problem solving. It's almost like they teach with the expectations that kids are too stupid to learn basic arithmetic. On one hand, you have these self-esteem classes that tries to booster self-confidence in academic abilities... on the other, the very teaching system they try to implement expects kids to fail and does nothing to help build confidence in their actual math abilities... I think it spells disaster... very sad. I hope this does not spread.
Oberon: Weapons of Math hey? What were you trying to teach them? Angle and initial velocity calculations for how to hit the pentagon with a missile? j/k
