Simulator Adjustment subtraction limits 20 online. Subtraction and addition of numbers with a transition after a dozen

Preparing for the game - Settings

Any parameters and settings may be changed by anything, even during the game.
Initially, the game is configured as:
- Type of computing - addition to 10
- Prize 1. - chocolate, prize 2. - biscuits
- In the gaming session 10 computing (arithmetic examples)
- Percentage of examples that need to be solved correctly to obtain a premium 1 - 90%
- Percentage of examples that need to be solved correctly to obtain a bonus 2 - 70%
You can choose any other type of computing - depending on what the child knows and what is going on at the school at the moment. Types of computing in the game:
- Addition, subtraction, addition and subtraction (inversion):
  - To 10
  - Up to 20. (with the transition after the top ten)
  - Up to 20 (with the transition after the top ten and without)
  - Up to 30.
  - Up to 100.
- Multiplication, division or any combination - on 1, -n 2, -n 3 ....... et al. Up to 10
- Comparison of numbers
Install how many examples will be in the gaming session. It is better to start with a small number of attempts - 5 or 10, so as not to discourage the desire to continue the game. When a child will increase Nadoi :) Improve indicators, you can move to a serious game with 100-200 examples.
Make the percentage of correctly solved examples for which 1 and 2 premiums are issued. To begin with, it is better to lower the percentage. For example, choose 70 and 50 percent for 1 and 2 premiums, respectively. Later, the bets can be increased to 90 - 70. or even up to 98% - 95% for very terrible clever children :). Make only digits, no sign%!
Record the awards that the child will receive for 1 and 2nd place.
Settings will be saved with a cookie (small script) and restored when you open the game page in the browser.

Now you can start the game!

To start the game, click the Start button.
When an example appears on the screen, the child must make the answer after the sign "\u003d"
If you play "comparisons", you need to make an appropriate sign :. For this convenient to use the buttons that will appear next to the button on
After the result is made, you need to click on the OK button (or ENTER on the keyboard) to check if an example was resolved correctly.
If the example was solved correctly, "correctly" appears on the screen. If not, "wrong" and the right answer. At the same time, the game will consider the percentage of correctly solved examples.
To proceed to the next example, you need to press the button on
When the session is over, the premium will appear on the screen, which the child won (or "did not win anything") and the percentage of the properly solved for the session of the examples
To start a new session, click the Start button first.

Great expectations:)

What can you expect from this game? Helpful care in the passage of the school program!As a rule, in 5-7 days, in which the child plays for 30-40 minutes, it firmly assimilates the next type of calculation (for example, addition to 20 with the transition after the top ten). And practically ceases to make mistakes in the class.

Oral account simulator - Easily and significantly increases the intellectual potential of man.

The result of the acquisition of skills and system of regulatory qualification will be awarded sports discharge (I category, II category, III discharge, a candidate for the masters of sports, a master of sports and grandmaster).

People from the group are allocated both by the ability to beautifully and correctly speak and by the ability to quickly read in the mind, and include them, as a rule, to the intelligent category. Schoolboy the ability to quickly believe in the mind allows you to more successfully learn, and the engineer and scientist reduce the time of obtaining the result of their activities.
Us need not only to schoolchildren, but also engineers, teachers, medical workers, scientists and managers of different levels. Whoever thinks quickly, it is easier to learn and work. Us is not a toy, although entertaining. It allows you to return the disciple on those "rails", from which he fell sometime; increases speed and quality of information perception; disciplines and makes accuracy in everything; Teaches to notice details and trifles; Tears to save; creates images of objects and phenomena; Allows you to foresee the future and develops human intelligence.
"Euroremount" in the head should be started with simple arithmetic actions that allow you to structure the brain.
The ability to quickly consider in the mind gives a student self-confidence. As a rule, those who are well study at school or in high school are considered faster. If the lagging student is learned to be quickly considered in the mind, then it will definitely affect its performance, and not only in natural, but in all other subjects. This is proven by practice.
Arbitrary attention and interest during an oral account changes the wandering look behind the student on a fixed, and the concentration of attention reaches several floors of the depth of the subject or process that is studied.
"The study of mathematics disciplines thinking, tears to the correct verbal expression of thoughts, to accuracy, compression and clarity of speech, brings up perseverance, the ability to achieve the intended goal, develops performance, contributes to the correct self-assessment of the ownership of the subject that is studied." (Kudryavtsev L.D. - Member Cor. RAS. 2006.).
A student who learned to be quickly considered in the mind, as a rule, begins to think faster.
One who, by nature, well considers, will naturally find the mind and in any other science, and the one who considers slowly, learning to this art and mastering them, will be able to improve their mind, make it sharper (Plato).
The acquired oral account skills is enough for 5 to 10 years, and others for life.
Our descendants will be easier to learn and receive knowledge. However, the culture of the oral account will always be an integral part of the universal culture.
Who quickly considers in the mind, one, as a rule, thinks clearly, quickly perceives and deeper sees.
The development of the US develops the figurative, diagram and systemic thinking, expands the RAM, the range of perception, teaches to think about several moves forward, improves the quality of thinking, operating with the quantitative characteristics of objects.
CSS increases the clarity of thinking, self-confidence, as well as volitional qualities (patience, perfection, endurance, hardworking). Takes off to the deep and sustainable concentration of attention, speculation and contracting of the initiated phrases (especially in preschoolers and primary school students).

The very first examples with which the child meets before school is addition and subtraction. It's not so difficult to calculate animals in the picture and, by jumping over the unnecessary, calculate the remaining. Or shift counting sticks, and then count them. But for a child, it is somewhat harder to operate with naked numbers. That is why practice needs and once again practice. Do not learn to do with the child and in the summer, because for the summer, the school program from a small head simply dispends and long have to crawl lost knowledge.

If your child is first and only goes to the first class - start with the repetition of the composition of the number on houses. And now you can also be taken for examples. In fact, addition and subtraction within ten is the first practical application of the child's knowledge of the number.

Click on the pictures and open the simulator in the maximum magnification, then you can download the image to your computer and print in good quality.

It is possible to cut A4 in half and get 2 sheets with tasks if you want to reduce the load on the child, or give to decide on the column per day if we decided to work out in the summer.

We decide the column, we celebrate the success: Tuchka - not very well decided, smiley - good, the sun - wonderful!

Addition and subtraction within 10

And now the gaze!

And with skipping (windows):

Examples for addition and subtraction within 20

By the time the child would start learning this topic of mathematics, he should be very good, to know the composition of the number of the first ten. If the child does not mastered the number of numbers, it will be difficult for him in further computing. Therefore, constantly return to the topic of the number of numbers within 10, while the first-grader will not win it to automatism. Also, the first-grader should know what the decimal (discharge) composition of the numbers means. In the lessons of mathematics, the teacher says that 10 is, in a different way, 1 dozen, therefore the number 12 consists of 1 tens and 2 units. In addition, the unit is folded with units. It is on the knowledge of the decimal composition of the numbers that the methods of addition and subtraction within 20 are based without transition through a dozen.

Examples for printing without transition through a dozen mixture:

Addition and subtraction within 20 with a transition after a dozen Based on the receptions of adding up to 10 or the recess to 10, respectively, that is, on the topic "Composition of the number 10", therefore, it is responsible for studying with the child of this topic.

Examples with a transition through a dozen (half of the sheet addition, half subtraction, the sheet can also be printed in A4 format and cut in half to 2 tasks):
