Computer programs for teaching preschoolers the basics of mathematics. Mental arithmetic learning at home Addition and subtraction program

While searching for literature on the topic of my work, I came across many computer programs that can be used to teach children the basics of mathematics.

Here are some of them: “Count it!”, “Multiplication Table 1.1.0.35”, “Primerchik 1.4 Rus”, “Arithmetic with pleasure!!!”.

“Count it!” - a program for teaching the basics of mathematical calculations. Topics available include adding and subtracting numbers within 10, forming a ten, passing through a ten, adding and subtracting tens, summing numbers up to 100, comparing numbers, measures of length, geometric figures. There is a section with tests that check the correctness, display the result of the solution and assign a grade. Tasks are generated automatically. Their number and time to solve can be changed. There are hints. Possibility of additional graphical display of solutions to examples. Musical accompaniment and sound effects. The program is intended for children of preschool and primary school age.

“Multiplication Table 1.1.0.35” -The main goal of the program is to learn the multiplication table in the shortest possible time. Each “column” of the table is a separate level with colorful animated graphics and pleasant music and sound accompaniment. Ability to set time intervals for solving tasks. The principle of choosing the correct answer from among those available is used. Control only with the mouse, in contrast to the tedious entry of numbers from the keyboard.

Primerchik 1.4 Rus" - A unique program that will give your child examples of addition and subtraction instead of you, help in memorizing the multiplication tables, teach him how to perform addition, subtraction and multiplication in a column.

"Example" can work in forced mode: the program will start when you turn on the computer, and until the child solves the number of examples/tasks you specified, he will not be able to play.

"Primerchik" has the following tasks in its arsenal (the complexity of the tasks is adjusted by the parents themselves depending on the age of the child):

Addition and subtraction. Starting from kindergarten, parents begin to give their children examples of addition. From the first grade, when working with your child at home, you already have to constantly come up with and come up with new examples. Gradually, examples are added with unknown terms, examples of subtraction, with an unknown minuend, subtrahend...

The Addition and Subtraction activity will do just that routine work for parents! Just indicate the range of values ​​of the addends or the minuend and the subtrahend, and your child will enjoy solving such examples on the computer!

Multiplication table. The child will be given examples from the multiplication table. Parents themselves will be able to indicate which examples to show, whether to give examples of division, and whether to find factors, divisors or dividends.

Expressions with brackets. This task will produce examples with parentheses. The child will indicate the order of actions, enter the answers in brackets, and then the answer for the entire example.

Column addition/subtraction/multiplication. As the name of these activities suggests, they will teach your child how to do addition, subtraction and multiplication.

“Arithmetic with pleasure!!!” - Developmental program for preschool children. The program is designed in a clear game form, with the help of which the child can practice his arithmetic skills. This not only contributes to the rapid assimilation and memorization of material, but also increases the general interest in the exact sciences among the younger generation.

All programs turned out to be interesting, exciting and educational in their own way. It seems to me that it will be useful for preschool children to get acquainted with these programs; these programs will be much more useful than ordinary games of cards, shooting games, racing, etc. Working with such programs, the child will have the idea that he is playing a computer game, and at the same time, he will develop and learn.

Free program and arithmetic game allows children learn addition, subtraction, multiplication and division of numbers, including single-digit, double-digit, natural positive numbers within the subject of mathematics using colorful pictures of fruits and berries, insects and amazing animals, as well as images of other nature characters.

The educational game program is intended for preschoolers and children of grade 1, grade 2, grade 3 of primary school and gives the opportunity, in the form of a math game, to choose one of the arithmetic operations on numbers: addition, multiplication, subtraction or division.

With the help of bright and colorful images, children learn with interest how to perform basic operations with numbers.

The child can both study operations on single-digit and double-digit numbers and, through training, consolidate the material. In the game, the student can independently choose not only an arithmetic operation to study, but also one of three difficulty levels.

In the program, the child is shown one by one simple examples and their display in the form of an appropriate number of pictures. There is no need to enter the numerical result of the example; the student selects with the mouse the number of pictures corresponding to the answer.

For example, when learning addition at the initial stage, the child counts the number of apples in the first and second terms together and selects the corresponding number of apples with the mouse in the answer. The program shows the correctness or incorrectness of the answer and counts their number.

Simulator-game Arithmetic

This game or simulator contains 12 examples at each difficulty level. If necessary, you can increase the number of examples to 23 by adding invented examples to the corresponding text files. In this case, new pictures are automatically offered, although the mode for adding or subtracting, multiplying or dividing numbers may be activated.

1. Unpack and run the game (file Sapling 2.0.exe);
2. In the top menu, select an arithmetic operation (Addition, Subtraction, Multiplication, Division) and difficulty level (1, 2, 3);
3. Click "Start" in the menu.

Mental arithmetic trainer— easily and significantly increases a person’s intellectual potential.

The result of acquiring skills and achieving normative qualifications will be the assignment of a sports category (I category, II category, III category, candidate master of sports, master of sports and grandmaster).

1. People from the group are distinguished both by their ability to speak beautifully and correctly, and by their ability to quickly count in their heads, and they are usually classified as smart. For a student, the ability to quickly count in his head allows him to study more successfully, and for an engineer and scientist, he can reduce the time it takes to obtain the result of his work.
2. CS is needed not only by schoolchildren, but also by engineers, teachers, medical workers, scientists and managers at various levels. Those who count quickly find it easier to study and work. The US is not a toy, although it is entertaining. It allows the student to return to those “rails” from which he once fell; increases the speed and quality of information perception; disciplines and produces precision in everything; teaches you to notice details and little things; teaches you to save; creates images of objects and phenomena; allows you to foresee the future and develops human intelligence.
3. “European-quality renovation” in your head needs to start with simple arithmetic operations that allow you to structure your brain.
4. The ability to quickly count in your head gives the student self-confidence. As a rule, those who do well at school or university do the fastest math in their heads. If a lagging student is taught to quickly count in his head, this will certainly have a beneficial effect on his performance, and not only in natural sciences, but also in all other subjects. This has been proven by practice.
5. Voluntary attention and interest during oral counting changes the wandering gaze of a lagging student to a fixed one, and the concentration of attention reaches several levels of depth in the subject or process that is being studied.
6. “The study of mathematics disciplines thinking, accustoms one to the correct verbal expression of thoughts, accuracy, conciseness and clarity of speech, fosters perseverance, the ability to achieve the intended goal, develops efficiency, and promotes correct self-esteem of mastery of the subject being studied.” (Kudryavtsev L.D. – Corresponding Member of the RAS. 2006.).
7. A student who has learned to quickly count in his head, as a rule, begins to think faster.
8. The one who by nature counts well will naturally discover intelligence in any other science, and the one who counts slowly, learning this art and mastering it, will be able to improve his mind, make it sharper (Plato).
9. The acquired mental arithmetic skills will last for some people 5-10 years, and for others for a lifetime.
10. It will be easier for our descendants to learn and gain knowledge. However, the culture of mental calculation will always be an integral part of universal human culture.
11. Those who count quickly in their heads tend to think clearly, perceive quickly, and see more deeply.
12. Mastering CS develops figurative, diagrammatic and systemic thinking, expands working memory, range of perception, accustoms one to thinking several moves ahead, improves the quality of thinking in terms of the quantitative characteristics of objects.
13. CS increases clarity of thinking, self-confidence, as well as strong-willed qualities (patience, perseverance, endurance, hard work). Teaches deep and sustained concentration of attention, conjecture and finishing of begun phrases (especially in preschoolers and primary school students).

Arithmetic is the most basic, basic section of mathematics. It originated from people's needs for counting.

Mental arithmetic

What is called mental arithmetic? Mental arithmetic is a method of teaching quick counting that comes from ancient times.

Currently, unlike the previous one, teachers are trying not only to teach children how to count, but also trying to develop their thinking.

The learning process itself is based on the use and development of both hemispheres of the brain. The main thing is to be able to use them together, because they complement each other.

Indeed, the left hemisphere is responsible for logic, speech and rationality, and the right hemisphere is responsible for imagination.

The training program includes training in operation and use of tools such as abacus.

The abacus is the main tool in learning mental arithmetic, because students learn to work with them, move the dominoes and understand the essence of the calculation. Over time, the abacus becomes your imagination, and students imagine them, build on this knowledge and solve examples.

Reviews about these teaching methods are very positive. There is one drawback - the training is paid, and not everyone can afford it. Therefore, the path of a genius depends on one’s financial situation.

Mathematics and arithmetic

Mathematics and arithmetic are closely related concepts, or rather arithmetic is a branch of mathematics that works with numbers and calculations (operations with numbers).

Arithmetic is the main section, and therefore the basis of mathematics. The basis of mathematics is the most important concepts and operations that form the basis on which all subsequent knowledge is built. The main operations include: addition, subtraction, multiplication, division.

Arithmetic is usually studied at school from the very beginning of education, that is. from first grade. Children master basic mathematics.

Addition is an arithmetic operation during which two numbers are added, and their result is a new one - the third.

a+b=c.

Subtraction is an arithmetic operation in which the second number is subtracted from the first number, and the result is the third.

The addition formula is expressed as follows: a - b = c.

Multiplication is an action that results in the sum of identical terms.

The formula for this action is: a1+a2+…+an=n*a.

Division- This is the division of a number or variable into equal parts.

Sign up for the course "Speed ​​up mental arithmetic, NOT mental arithmetic" to learn how to quickly and correctly add, subtract, multiply, divide, square numbers and even extract roots. In 30 days, you'll learn how to use easy tricks to simplify arithmetic operations. Each lesson contains new techniques, clear examples and useful tasks.

Teaching arithmetic

Arithmetic is taught within the school walls. From the first grade, children begin to study the basic and main section of mathematics - arithmetic.

Adding numbers

Rules of arithmetic

The order of operations in an expression is very important!

If the example looks like 2+3-4, then the order in it can be whatever you want. Because addition and subtraction operations have the same priority. If we do the addition first, we get: 5-4=1, and if we do the subtraction first, then: 2-1=1. As you can see, the result is the same.

Similarly with the expression for multiplication and division. Multiplication and division operations have the same priority. For example, 2 8:4. Let's do the multiplication first: 16:4=4, and if division: 2 2=4.

Order makes sense when an expression mixes addition or subtraction with multiplication or division. For example:

2+22. The first action is to perform ALL operations of multiplication and division, and only then addition and subtraction. That is, the expression 2+2 2 = 2+4=6.

But there are parentheses in the expressions. Parentheses tend to change the order of operations. Consider the previous example, only with brackets: (2+2)*2. In this case, the operations inside the brackets are performed first, and then outside the brackets in the order: 1. Multiplication and division 2. Addition and subtraction.

So, (2+2) 2=4 2=8.

As you can see from the examples, parentheses have a role. And the order of operations is the same.

Arithmetic lessons

Arithmetic lessons - school lessons, up to the sixth grade. Then mathematics opens its sections: geometry and algebra, and later trigonometry.

Arithmetic 5th grade

In the fifth grade, students begin to study topics such as fractions and mixed numbers. You can find information about operations with these numbers in our articles on the relevant operations.

Fractional number is the ratio of two numbers to each other or the numerator to the denominator. A fractional number can be replaced by division. For example, ¼ = 1:4.

Mixed number– this is a fractional number, only with the integer part highlighted. The integer part is allocated provided that the numerator is greater than the denominator. For example, there was a fraction: 5/4, it can be transformed by highlighting the whole part: 1 whole and ¼.

Task No. 2:

Arithmetic 6th grade

In 6th grade, the topic of converting fractions to lowercase notation appears. What does it mean? For example, given the fraction ½, it will be equal to 0.5. ¼ = 0.25.

Examples can be compiled in the following style: 0.25+0.73+12/31.
