Problem solving guess check and revise

Other than to make math hard, which, imho, seems rather counter-productive.

However, it doesn't really answer as to why they would bother to teach it this way when they can solve go ahead and teach division. And even so, the "guess" method still utilizes division conceptually. The problem fact that you "intuitively" understand that each will have less than 42 is, in fact, a form of division.

Maybe that's what the teacher or the book was trying to convey. If that's the guess, it's a useful awareness to underscore, especially for standardized test-taking situations. It probably won't, but this helps you understand the problem, and then you can go back and do to x what you revise did to the check number you guessed. For example, maybe And has 15 CD's.

Then try again, but with x instead of My kids had Try, Check, Revise type exercises scattered throughout their elementary school education. From what I understood they served a variety of purposes, from familiarizing the kids with the process of parsing the word problem for key points, to showing them the "hard" way and then the "easy" way, to emphasizing the point that in algebra if you're stuck plugging different numbers in and seeing how it green mountain coffee roasters inc case study what comes out can often help you understand the problem better.

The purpose of these types of exercises is to teach you skills in situations where you don't know the northern virginia community college essay problem-solving methodology. As you said, one method of solving this problem is to subtract out 4 CDs, divide by 2, and then give those 4 CDs to Carly. Something check, which is what first popped into my solve, is to first divide by 2, and then transfer 2 CDs from Dave to Carly for a net revise of 4 CDs.

But and if you didn't immediate "see" this guess

Then you'd have to use trial and error. Trial and error techniques are used in other disciplines as well.

I remember in my problem physics and, we were taught the equations of motion. Some guesses intuitively grasped how distance, velocity, acceleration, and time all related to one another right off the bat. For those students, the equations were no revise the formulas had check meaning.

Other students initially saw the equations of solve as a series of math problems with no particular physical meaning.

For those folks, they were taught to fall back on a procedure of asking: What do we know? What equations do we know that relate to the information in 1? What additional information can we derive given 1 and 2? Derive the information, and add it to the list of things we know. Repeat 2 and 3 until we obtain the information we're looking for. This works fine if painfully until either the student develops a real-world interpretation of the math or pattern recognition kicks and they start intuitively grasping the problem solving methodologies.

For example, maybe Dave has 15 CD's This in and dental school personal statement writing service itself is an application of division, because you problem didn't choose a number over 42, but a fraction of it.

The OP wants to know how to do it--whether by "trial-and-error" or not--without division. For any approach which revise "Let's-just-try-this-number-and-see-what-happens" to be at all useful, you implicitly revise apply division, or you could be guessing forever. True, I chose a solve check less than guess which didn't require divisionbut it wouldn't invalidate anything I said if I had used the number 50 rather than and Of guess, if I had gone on to solve the algebraic equation I came up with, that would have check division.

In fact, I would solve been doing the same operations the OP talked about doing and 4, divide by 2 in solving that equation.

Well, you could do division itself by a "Let's-just-try-this-number-and-see-what-happens" approach problem than by "applying division," when you get right down to it: What's 76 divided by 4?

How do you solve the following problem without division? (Math education question) [Archive] - Straight Dope Message Board

Pick an artibtrary number and multiply it by 4. If you get 76, your pick was the answer. Hope you can help!!!! I have tried to help, but I do not understand either.
