New Common Core question

I LOVE this !!!!

If we all went through memorization of Multiplication tables, applied those to the rest of Division, Fractions, what else is there to squeeze out ?
Same with Addition and Subtraction - once you get it and learn how to add and subtract "carrying" over as needed, what else could you possibly need to function here ??

I am not the smartest math brain in the room but I can figure out everything on all those pages you posted in my head without any tables, etc...

Do I get a gold star and get to go to recess sooner ??? :)

I gotta write a ck to the school this week......

I want to do the same thing, but looked on line how to write 110.00 and couldn't find out

btw

The way we do/did math is now called "granny math".........
 
Math isn't always as set-and-done as one might think. Some "Mental Math" courses have given me good techniques ("tricks" some might say) that were never touched on in the classroom.

If nothing else, learning all sorts of different ways to do such stuff (yeah, including matrixes, tables, etc.) can help develop critical-thinking skills and maybe even improve one's ability to, uhm...think laterally.

Eh, I guess I just like most anything that encourages thinking, as long as the approach doesn't lead down a falacious path. But I also suppose that there's just *so* much to learn that they shouldn't waste time that could be better spent on various fundamentals.
 
Quote ----- Since I mentioned spreadsheets, Maybe Bill Gates is working on a new version of Excel that incorporates common core math.

The man that actually wrote Excel is one of my Clients.. He graduated from MIT..

One day his friend Bill Gates asked him if he could write a financial app and that is how Excel came to be..

Having used Excel a number of times, I can safely say for me, I will NEVER get to the end of what this man had coming out of his head.. Excel seems to go forever... :)

I thought VisiCalc was the first real spreadsheet as we know it today with Lotus 123 following next (both in DOS) and then Microsoft Excel (Lotus was slow) and took over the market. Excel did evolve in more ways than Lotus before it was just left as is.
 
Ron, the use of stimulant medications in children for ADD/ADHD is out of control. We have whole families of kids getting Adderall, Concerta, Ritalin, Dexedrine, Quillivant, etc...

For those not familiar what what these drugs are, they are schedule 2 (most restricted class of drugs legal to prescribe in USA) amphetamine based stimulants. Kids are being given heavy duty amphetamines to perform/behave in school, along with antidepressants, antipsychotics/anti-schizophrenics, and tranquilizers to be put to sleep at night.

It's not uncommon from where I'm from for TEACHERS to recommend parents put there children on amphetamines due to some perceived problem. Most child psychiatrist in my area seem to give almost EVERY child that leaves the office with a script for some "behavioral issue" the same cocktail of drugs. In actuality however, most of these scripts are just coming from the family Doc.

The worse part about it is - once the kids get on it - they rarely get off. Since use of amphetamines / stimulants results in tolerance (and dependence), the doses are increased and increased over and over again - well beyond what the manufacturer recommends and what has been studied.

What's coming down the road next is mandatory reporting of child abuse for healthcare practitioners. While in the surface this may sound "good", get ready for your kids to be pulled away from you and "interviewed" in a room by their Dr, dentist, pharmacist, or nurse during routine visits to be screened for "abuse" - regardless if there is reason to suspect it or not.

The neurological and psychological use of these drugs on the developing mind is unclear. While academic performance often does increase (you would have done great in school if you were on speed all the time too) - what is the cost of this?

As a parent of a child with ADHD I can say that you don't know what you are talking about. I saw first hand myself that there was something different about my son and his inability to concentrate and how the medication has helped him and help him change for someone just barely getting his work done to an A student. There is clearly something different about the way his brain works.
 
Back on the topic, I am sure common core is trying to make it build thinking rather than memorization. For example, during a business trip in Singapore, one supplier head who was educated in the UK said Singapore kids spend too much of their time memorizing and not enough thinking so when they get out of school they really do not resolve real problems as well as many western (like US, Germany, UK) kids. Are they smart yes but real problem solving is key..not who can tell you all the times table in 20 seconds.

But even here in college, I found that there was not enough practical application of math, physics, and general engineering (uses all learnings) to really come out as a better thinker. They were too busy trying to cram as much information in your brain in the time they have. For example, why is 1:10 important to know over 10:1 and I am not talking about gambling odds.

Stumbled across this thread...im only 32 but when i first heard of common core i was highly appauled....
I'd like to see a common core teacher do these type problems from contest math (number sense).
I did this all through jr high/hs and it even got me a scholarship to college.

They never taught me about any "tables" just tricks about how numbers/math works, little quirks here and there that allow you to do random math in your head very quickly with no scratch paper or anything to jot down on.

For instance...any 2 digit number multiplied by 101 is that same 2 digit number twice (22×101=2222--try it)

Knowing mathematical tricks like these may not help me a whole lot, but if my stock knowledge was memorizing some stupid table in my head so i can figure out 6 times x that goes across four tables to = 24 must mean that x is 4...well if you ask me we just added several unnecessary steps into the process of coming to that conclusion.

This is as far back as i could find on pdf online in a pinch


Oh and if u skipped one it's minus 5 pts and a correct one is only +3 if i recall...so u even have to do quick math on the fly...10 mins only for the test, answers only no markings at all.

So i can do that but common core sometimes confuses me. Alas there are several ways to arrive at a given destination.
 
My daughter is 9 and one of her questions was like explain the relationship between the 5 and the 4 in the number above. 54.

I said, write 5 is larger then 4 and her teacher checked it off as ok.

Ill see If I can photo some gems that come through the door.

I don't doubt your results one bit. The question is - at what cost are they being achieved? I could drop a couple of Adderalls and do paint correction from 5am to midnight without a brake. I could turn around the most trashed paint into a show stopper in record breaking time. Awesome results, right? .... Right now, I could only polish paint for maybe 2 hours until I needed a break or became bored...

In the long run - these drugs are quite bad. They are habit forming, dangerous, bad for your health, and IMHO basically a crutch. I'm glad they are working out for you now - but now isn't forever.

Fast forward to 20 years in the future. The child has now had 20 years worth of amphetamines overtaxing their adrenal, circulatory, and cardiac systems. Since these medication induce tolerance - higher and higher doses of amphetamines are now required to get the desired effect. Without their amphetamine drugs, the person becomes a human puddle - unable and unwilling to to complete the most basic human tasks.

If you think a child magically reaches a point where they just will stop taking this medications and "catch up" - you are woefully mistaken.

Most people that take these drugs for many years are taking way beyond what is considered safe dosages. Drs. continue to up the dose due to tolerance - as the person just can not function without the medication.

Then, the child eventually grows up into an adult. They are finding the workplace to be even more competitive and stressful than school. Additional drugs are added, doses are increased... Doses are so high now - tranquilizers are now required to sleep or sometimes even sit still. The person becomes "twitchy"... Their teeth start going bad way too young.

They have been taking antidepressants for at least the past 10 years to even out the ups and downs of the amphetamines. At this point, most Drs will add a mood stabilizer or an antipsychotic. Actually, MANY children are taking antipsychotic medication off the bat - and the parents don't even know it as such.

Somehow, the human race has existed (and often thrived) for thousands of years without giving our children amphetamines. I dunno. I believe their are other ways to motivate children to "concentrate" or to do well in school - besides drugging them.

I'm telling you this as a person that sees this every day as fairly hands on and clinical type pharmacist - not as someone who reads it on some website. MDs and big pharmaceuticals have many parents believing this stuff is acceptable and legit - all in the name of maximizing profits.

I'm just as bad - I hand it out every day for the dollar. Honestly - it's profitable... It's my opinion that it's the parents jobs to do their own research and make their own decisions. I'm just giving you my honest opinion based on my education and professional experience here. Take it as you may.

To say "I clearly don't know what o am talking about" is a mistake... I don't know crap about a lot of things - stuff like financial planning, building houses, and how to prepare ceviche. But, I do know quite about about medications and cars.
