Hello, my name is Shamil Akhmadullin and you on the channel
"School of fast reading and development of memory in children".
In this program "Learning to learn" I I answer the video questions of parents,
excited about learning their children. In the last program I answered the video question
Radzeli and she asked how teach your child quickly and
to count correctly. If you have not watched the first issue, then the link is above me.
Be sure to watch it. well and if we looked, then we continue!
I will talk about the methods that allow the child to his mathematical
thinking to bring to very high level That is, the more ways
fast counting a child knows, the better, the more developed and his mathematical thinking.
So, the first method. Usually the guys are very problematic to consider
such examples, for example, from 24 subtract 7, from 26 subtract 8, from 35 subtract 9.
Try to stop this video and note the time for how much your child will do.
this example. What to do? How to speed up the solution of such examples?
It can be done very simply: you can subtract first 10 and then
add 3, so we do when we subtract seven, but here again we subtract by analogy
add ten to 2, subtract 10 here
add one. Do this much simpler, according to 24
subtract 10 is 14, plus 3 is 17.
Need to bring this skill
to automatism. If the child did not understand how I performed these examples, then before
continue watching, rewind the video and view it again.
Give the child a few examples so that he can decide for himself.
The next method is multiplication. two-digit or three-digit numbers on
unambiguous. Well, for example, we need 56 multiply by 3 or
719 multiplied by 4. How to make it easier? We divide into tens and units and
50 multiply by 3 and, respectively, add 6 times 3.
It turns out 150 and 3 to 6 is 18, that is, we get 168.
Very easily and simply it can be done even in the mind. Now here is a little harder.
700 by four plus 10 by 4 plus 9 by 4. We get 2800 plus 40 plus 36
and this is also enough simply. It turns out 2876.
Even in the mind, with a certain dexterity,
can hold. If your child did not understand how
use these methods then rewind the video back and accordingly
Let him look at him again and understand how to carry out these examples. Well, I'll give
I will give two examples
which child must decide on their own. In the comments to this
video write the answers that you have have turned out.
The third method is dividing by 5. Usually guys can't instantly
divide the number by 5. Let's see how to do it simply,
for example, 720 is divided by 5. When divided by 5, you can simply divide first by 10 a
then multiply by 2. For example, 720 we divide by 10, and then
multiply by two and multiply by 72 at 2, it turns out 144.
This is significantly faster than trying to divide 720 by 5. Again, if the child does not
I realized how I turned this action rewind the video and watch again.
And I will give some examples in order so that your child will crack them before
screen.
Write in the comments an example and answer, which
turned in your child. The following quick counting method is called the butterfly method.
and on their courses nonmental we give arithmetic to his guys and
they really like it. With this method you can easily
add and subtract fractions. Well, for example, we have five seventh plus three fourths.
Take a pen of a different color to make it clearer and
draw a butterfly like this.
And we have a butterfly with a double mustache, The little thing with one mustache we get.
The result of multiplying 5 by 4 is 20, under the second
antennae 7 multiplied by 3, this is our 21. Well, here we multiply 7 by 4, this is 28.
raise this sign + and get The following: 20 plus 21 divide by 28.
We have the answer
respectively, one whole
28 and here we have 13. This way of adding and subtracting fractions
children like it a lot because like to draw a butterfly and so
the way it turns out is to solve faster. If your child does not understand how to perform
these actions then rewind the video and let the child look again
What did I do.
I will write examples to ensure that your child
independently counted how much it will turn out.
And let's take another example. using the butterfly method, for example 9/11 minus 1/7.
We draw our butterfly, antennae and what we have it turns out 11 to 1 is our 11,
and 7 by 9 is us 63. 11 multiplied by 7 is our 77. Here we have a minus sign,
accordingly, we get 63 -11 divided by 77. Everything is quite simple.
If the child did not understand how I did it, then
rewind the video and give the same example. Let the child do the same operations
what I did.
Quick counting methods significantly
more than i showed. But, if the child masters at least these four methods and will
use them when solving examples in school then his mathematical intelligence
will grow. What does mathematical intelligence mean? This means that when a child performs
completely different actions with numbers, in different ways, it grows
understanding in principle and mathematics, in principle arithmetic operations.
They are much easier to carry out various
mathematical operations. Well, I recommend you to bring all the same
understanding of these methods in a child to automatism. If something is not clear
reconsider to the level until the child can three or four examples without
tips yourself to decide. Thank you for attention!
Send your video questions to our email.
And I, Shamil Akhmadullin, in my program "Learning to Learn," will answer them.
Success in learning! Bye Bye!
