Matemática atual

É.... as coisas estão mudando... E eu começo a constatar que estou ficando velha ou muito ultrapassada.

Estava ajudando meu filho a estudar Matemática (da segunda série) para a prova de hoje e percebi que não se usa mais tabuada como antigamente. Agora, a multiplicação é utilizada com outra nomenclatura: dobro, dobro do dobro e dobro do dobro do dobro. Deu para entender?

Estou falando da multiplicação de 2, 4 e 8. Para se chegar ao número 16, a professora diz, por exemplo: é o dobro do dobro de 4...

Se por um lado, esta forma estimula as crianças a pensarem de uma maneira lógica, nós aqui (os pais ) ficamos meio perdidos com este progresso. Eu, por exemplo, estou re-aprendendo muitas coisas, dentre elas: a régua de cousiner (que nunca tinha ouvido falar), as contas de diminuir tirando emprestado o número do lado, e a utilização de gráficos e tabelas para representar as multiplicações.

Acho este método atual muito mais interessante e fascinante. Faz a criança pensar e raciocinar de uma forma prática, lúdica e criativa. Além de estimular desde cedo a criança a ter noções de espaço!!!

Um dos exercícios propostos era desenhar um quadrado de 8 linhas e 10 colunas e dividir depois em 5 retângulos idênticos.

Deixei meu filho fazer e fiquei observando. Para ele foi super fácil. Ele desenhou o quadrado e depois foi visualmente resolvendo a questão. Já para mim, tive que reler várias vezes o enunciado para perceber o que era pedido. Multipliquei primeiro, depois dividi... e só então consegui desenhar. Ele resolveu tudo apenas desenhando o que era pedido...

Afe!

Dobro do dobro do dobro? Nunca ouvi falar nisso.

Sou do tempo da tabuada. Elas eram vendidas nuns livretinhos em papel vagabundo, no centro da cidade. A gente decorava.

Quando eu ia pra casa do meus avô ele "tomava" a tabuada dos netos. O evento metia medo nos meus primos e eu me divertia. A gente ficava na frente dele, com a mão espalmada e ele, com uma reguinha de madeira, pronta pra dar uma "reguada" a cada erro. Meus primos saiam com as mãos vermelhas. Eu nunca senti aquela dor. Acertava tudo, saia com a mão intacta, mas não posso negar que senpre tive uma certa inveja por não ter, nunca, sentido aquela dor.

This might be a bit off-topic but I believe there are a lot of smokers here on www.blogger.com. I have recently decided to find a good manufacturer of e-cigarettes. I'm done with paying so much for normal smokes.A friend recommended [url=http://www.insanereleases.info/greensmokef.html]G Smoke[/url] According to their website this is how they described their product:
"Green Smoke offers supreme Electronic cigarettes with spendable cartridges that produce the highest smoke volume in the industry. With a collection of flavors and nicotine levels, Green Smoke's™ patented product offers convenience and exhibit performance that is unmatched. G Smoke products have been independently tested for safety."
I'm thinking of buying them. Anyone else have experience with this e-cigarette?

You must have seen Ranbir Kapoor’s wonderful chemistry with Katrina Kaif in Ajab Prem Ki Ghajab Kahani.

Katrina is really exited to romance Ranbir, obviously in reel life. Katrina is really eager to be a part of Ashtvinayak’s next film that casts Ranbir.

However she is well known to this fact that her looks as well as accent can not relate

Depending on what your destination is and how long you plan on making your trip for, the airfare may be the priciest expense. Because of this, finding a great deal on the airfare becomes extremely important. The more money you are able to save on the plane tickets, the more money you will be able to use toward your actual vacation.

When it comes to purchasing your airline tickets, the sooner the better. This goes for basically anywhere you plan on traveling. When you purchase a ticket sooner, lets say several months before the trip, there will be less of a demand, which will drive the price of the ticket down. However, on the flip side, as the day of the desired flight approaches, the flight's seats will begin to fill up. As fewer and few seats become available, the higher the demand will be, which will drive the price up. Booking the flight in as far advance as you can may save you hundreds of dollars in the long run.

Flying during the middle of the week is generally the cheapest time to fly. Fewer people travel during mid week than on Friday through Sunday. If at all possible, fly out on a Tuesday or Wednesday. You may actually find prices significantly less expensive on the Wednesday than the Sunday of the same week.

Looking for airfare online will probably be your best be at securing the cheapest possible flight price. There are multiple booking agencies which specialize in finding the cheapest airfare. However, to save time, go to Bing.com, which offers a comprehensive flight search option. Bing will search other travel sites (Expedia, Priceline, Hotwire, etc.) and display the cheapest flight form each site. From here you will be able to decide which website offers the best deal.

Students can often find discounted airfare by visiting STA.com. This is the Student Travel Association, and it can sometimes find less expensive airfare for the traveling student. This isn't always the case, but it doesn't hurt to look.

In 1959 phentermine first received approval from the FDA as an appetite suppressing drug. Phentermine hydrochloride then became available in the early 1970s. It was previously sold as Fastin from King Pharmaceuticals for SmithKline Beecham, however in 1998 it was removed from the market. Medeva Pharmaceuticals sells the name brand of phentermine called Ionamin and Gate Pharmaceuticals sells it as Adipex-P. Phentermine is also currently sold as a generic. Since the drug was approved in 1959 there have been almost no clinical studies performed. The most recent study was in 1990 which combined phentermine with fenfluramine or dexfenfluramine and became known as Fen-Phen.[citation needed]
In 1997 after 24 cases of heart valve disease in Fen-Phen users, fenfluramine and dexfenfluramine were voluntarily taken off the market at the request of the FDA. Studies later proved that nearly 30% of people taking fenfluramine or dexfenfluramine had abnormal valve findings. The FDA did not ask manufacturers to remove phentermine from the market.
[url=http://www.buyphentermine1.com]buy phentermine online[/url] Phentermine is still available by itself in most countries, including the U.S. However, because it is similar to amphetamines, it is classified as a controlled substance in many countries (including Australia). Internationally, phentermine is a schedule IV drug under the Convention on Psychotropic Substances.[1] In the United States, it is classified as a Schedule IV controlled substance under the Controlled Substances Act.
Looking forward, Phentermine is being studied with another medication for obesity. The experimental appetite suppressant drug Qnexa is a mixture of Phentermine and Topiramate.
Phentermine, in doses clinically used, works on the hypothalamus portion of the brain to release norepinephrine, a neurotransmitter or chemical messenger that signals a fight-or-flight response, reducing hunger. Phentermine works outside the brain as well to release epinephrine or adrenaline causing fat cells to break down stored fat, but the principal basis of efficacy is hunger-reduction. At high doses, phentermine releases serotonin and dopamine as well, but such doses are never used in clinical medicine.

Uncashable Bonus. This is the so-called 'sticky' bonus. This can never be cashed, but its usefulness lies in that fact that it stays in your account and enables you to use the bonus account to 'leverage' higher wagers. These free casino chips stay latent in your account simply to allow you to do things which you otherwise could not.

In addition to the play rhough requirement there are requirements for the maximum allowable bet per hand. In his case we averaged all three deposits and his maximum bet is $46 per hand.

- Have a budget and stick to it. Decide how much you can afford to spend and bet wisely. Pace your betting, so you don't blow your stash on one risky bet. Before you know it you will be signing off, your online casino experience a short one.


First, never choose a casino on the sole basis of his ranking in the search engine results. They are not necessarily good rankings on how a casino. You must go through several online casino sites to compare the benefits in detail and then make a decision. For example, should offer a bonus and, if so, how much. Are there any special promotions available?
