#CommonCore This is how the Government gets the unemployment rate.
Is it bad when the kid who did this is smarter than the teacher?
Please tell me this is satire.
Are these people saying if they have 8 pieces of candy plus 5 pieces of candy they don’t know how they can eat just ten pieces leaving three for later? Come on people. Don’t deprive your kids of knowledge because you don’t understand how to regroup numbers.
Read the question. How do you make 10 when adding 8 + 5? There’s no effective use of “regrouping” in this question because the question (which is an embodiment of its own set of rules, as are all such questions) does not provide for transitory results. You have not completed the task of adding 8 + 5 by only adding 8 + 2. Put another way, if the question were “Does 8 + 5 = 10” and you answered Yes, you would be wrong, even though under the set of truths you are trying to bring to the “How do you make 10…” question, Yes would be a correct answer because, you could argue with the test proctor (or the person auditing your income tax return), “I get 10 on the way to counting to 13.”
And if I’m going to bring my own set of truths to the question anyways, I might as well conclude that the answer is “Aardvark!” or “50,000”. Saying that you can bring your own set of truths to the question and simply ignore the fact that 8 + 5 = 13 and not 10 is to basically say you can ignore truths when they do not suit your own arrogant view of things. Try doing that on your income tax return and let us know how it works out.
The old “Sam has 8 candies and Sally has 5. How can they give 10 candies to Sid? How many candies do they have left?” That at least has some basis in logic. This question is just nonsense disguised as new age math compliments of Bill Gates and the Common Core hipsters.
Indeed, this looks more like the kind of math question that would pop up in a Monty Python skit. At which point, once again, the answer must be “Aardvark!”
And another thing. Some parents like to be able to help their kids with homework. But if homework is so absurd as to defy common sense, how can parents be involved?
Just because you don’t grasp the effective use doesn’t mean there isn’t one. Say the question was how do you make 10 from 13? Could you answer that? Instead the question is how to make 10 from 8 + 5. 13 = 8 + 5 = 8 + 2 + 3. 8 + 2 = 10 + 3 = 13. This is a simple regrouping question. A fairly easy one. No where does anyone say 8 + 5 = 10. The question is how to get 10 from 8 + 5. There are many possible ways. And the set of rules that apply are basic arithmetic. So if basic arithmetic is as absurd as a Monty Python skit to you don’t blame math. And all for parents helping their kids. But that is no reason to hold your kids back to only what you understand.
