Multiplication table – the perfect wife Blog
And yet you have repeatedly heard the opinion that the level of math education is falling.

That’s when my children were students in the second grade, I clearly understood why decreases the level of mathematical education at school. It was in the second grade during the laying of the Foundation of mathematics education there is such a giant irreparable hole, which has no crutches in the form of calculators are not buddies.

But the main problem is in the multiplication table. Look at the notebook in a cage that is at your kids school.
I went shopping in search of notebooks. And still, all the same pattern.

There are notebooks even worse (for seniors) on which the multiplication tables, but there is a bunch of meaningless formulas.

So why is this a bad notebook? The unsuspecting father sees that notebook multiplication table. Like, life on the notebooks was the multiplication table? What’s wrong?

And the problem is just that the notebook is NOT a multiplication table .

The multiplication table, my dear readers, here it is:

Sometimes the same table is even called the beautiful word “table of Pythagoras”. Upper left column can not take it, just a basic rectangle.

First, it is a table. Secondly, it is interesting!
No child in their right mind would consider the discharged columns of the examples.
No child, like the genius she was, would not be able to find examples written in a very interesting and complex patterns.
Well, generally, when a teacher says: “learn the multiplication table”, and the child even before a table doesn’t see she knows that math is a science, where ordinary things are called something different and have lots to learn, and to understand nothing is possible. And in General, it is necessary to do so, as it is written” and not “in a way that makes sense”.

Why “table” is better?
First, there is no debris and the noise in the left side of the examples.
Secondly, it is possible to think. Even here, nowhere is it written that this multiplication is a simple table.
Third, if she is constantly at hand and the child she constantly stumbles, she Willy-nilly start to memorize these numbers. In particular, the question “family of eight” will never answer the 55 the number 55 is generally in the table and there was not!
Remember the columns of examples can only children with abnormal memory. In the “table” we need to remember a lot less.

In addition, the child machine searches for patterns. And she alone finds them. Even such laws are children, still do not know how to multiply.
For example: numbers, symmetric about the diagonal are equal. You know, the human brain is configured to look for symmetry, and if it finds it and notices — very happy. What does this mean? This means that the permutation of places of the factors does not change the product (or what multiplication is commutative, in other words).

You know, the baby notices it herself! And the fact that people come up with she will remember forever, in contrast to the fact that it has jagged or said to her.
Remember your exam in the University in mathematics? You forgot all the theorems of the course, except that you got, and you had to prove to her vicious teacher! Well, it is if you didn’t cheat, of course. (I’m exaggerating, but it is almost always close to the truth).

And then the child sees that you can not the entire table to teach, but only half. If we know the step of multiplying by 3, then we do not need to remember the “eight by three”, and it is enough to remember the “three eight”. Already half the work.

And besides, what is going on — it is very important that your brain does not take dry information in some obscure bars of examples, and thinking and analyzing. That is, trains.

Except commutative multiplication you can see, for example, such a remarkable fact. If you poke in any number and hold the rectangle from the beginning of the table to this number, the number of cells in the rectangle is your number.

And here, the multiplication is already receiving more profound meaning than just shorthand for several similar terms. There is a sense and geometry — area of a rectangle is the product of its sides.

And you have no idea how much easier it is to share that spreadsheet!!!

In short, if your child is in second grade, her print here this the right multiplication table. Hang on a big wall, so she looked at her when doing homework or sitting at the computer. Or some suffering from this nonsense. And print and laminate a small (or write on the cardboard). It in school carrying around and simply conveniently at hand. (will not interfere in this table to select the squares on the diagonal to see better)
My children have here. And they really helped in the second grade and still helps me a lot in math class.

That is, honestly, just average score in mathematics will increase, and the child should stop complaining about that stupid math. And in addition, in the future your child will also be easier. She will know that you have brains, and not cram. And little understand, she will learn to do it.

And I repeat: in the examples the bars there is nothing wrong. And the amount of information they contain is the same as in “table”. But no good in such instances either. It — information trash, you’re not suddenly find.
