Manual can be used ...
The manual contains 3,000 new examples in mathematics on one of the basic topics - "account within 100". Like any other topic, it requires attentive understanding and durable consolidation. A feature of this publication is a large font.
As practice shows, the student fully understood the topic if it decides the example and records the answer within 4-7 seconds. In this case, we can say that the skill of the account is brought to automatism.
Each page contains 6-7 columns, an average of 35 examples. At the end of the column is recorded time spent student on the decision. In the lower left corner, the control numbers are indicated: the ideal time for solving one column, satisfactory and the result, which should make the disciple think.
The teacher is difficult to check such a number of examples, so it is better if the time spent on the solution of each column will mark adults.
To achieve good results, you need to solve one page every day.
The manual can be used as an additional material in the lessons of mathematics, as well as for housekeeping.
In mathematics, of course, it is important to be able to think and think logically, but practices in it are no less important. Half errors on the exams in mathematics are made due to improper calculation of simple actions with numbers - addition, subtraction, multiplication, division. And it is important to work out these skills even in elementary school. In order not to miss anything, it is necessary to systematically deal with the child on special notebooks - simulators. They allow you to work out mathematical skills and skills and bring them to automatism. Simulators are diverse, not necessarily downloading them all, enough one or two people. The benefits can be used in working with younger schoolchildren regardless of the program on which training is conducted.
Mathematics. We solve examples with a transition after a dozen.
Notebook for testing the skills of addition and subtraction with the transition through a dozen. Not just examples, but interesting games and tasks.
Quest cards. Mathematics. Addition and subtraction. Grade 2.
Convenient cards for Teachers of Serbes. 2 options for addition and subtraction of one species. It is suitable for organizing independent work on mathematics, depending on the promotion of the program.
Mathematics. Addition and subtraction in the range of 20. 1-2 classes. E.E. Kochuurova
In different courses of mathematics, the topic of addition and subtraction within 20 is studied or at the end of 1 class, or at the beginning of the 2nd. In any case, the manual will help consolidate the studied methods of manipulation with numbers, in some tasks these methods are presented in the form of peculiar prompts. In the course of independent work with notebook, the child focuses on a sample of implementation and algorithmic prescriptions. The ability to use such prompts in studies will allow the student not only to find and use the necessary information during the task, but also to carry out self-test.
The notebook begins with the development of the skills of addition and subtraction within 10, this part is suitable for first grades.
Mathematics gym notebook for grade 2
The notebook contains not only examples of addition and subtraction, but also the translation of units to each other, and comparing the results of calculation (more or less).
3000 examples in mathematics (account in the range of 100 part 1)
Simulator with a bill for time. Time to span on the solution of one column of examples and record at the bottom in the window. Pay attention to the columns that the child has solved more than 5 minutes, which means it has difficulty in this type of examples. Examples are given for addition and subtraction within ten and with a transition through a dozen, addition and subtraction of dozens, manipulation within hundreds.
Account from 0 to 100
This proper is given many examples of addition and subtraction to consolidate the oral account skills within 100.
We consider it right. Workbook in mathematics. G.V. Bel
The notebook is also made in the form of a simulator, solid examples and equations. It starts from the account within ten, hereinafter - within hundreds (addition, subtraction, multiplication and division), ends with comparison of equations (examples with signs greater than, less, equal).
The benefits will be useful and teachers of primary classes in their work, and parents for households with children, in particular, in the summer holidays. The tasks of different levels of complexity will allow a differentiated approach to learning.
Several books included in the total series of "3000 examples in mathematics" are assigned to the interpretation. Each is devoted to one of the most important software topics that are studied in 1-4 grades of primary school. The number of examples in books is different and increases from class to class, from the topic to the topic. In total, 3000 mathematical examples are offered to work out the skills of an oral account. This manual presents the material aimed at creating an oral account skills on the topic "Account within 100" for grade 2. The oral account is developing the intelligence and attention of students, brings up mathematical resourcefulness and strengthens memory. The correct placement of the oral account in elementary school involves daily and short-term (from 5 to 10 minutes) exercises. Sequential execution of assignments of the manual will help students master the skills of the oral account of all forms: a fluked auditory account. (The teacher verbally calls an example and in peace, after a few seconds, receives an answer.) Spectatic account. (Examples are recorded, and the answers are called either verbally, or recorded by students.) Combined account. (The teacher dictates examples, and the student records the answers.) Oral solving tasks. The speed of the score arises as a result of long workouts. But in the first place should be the awareness of those or other techniques of oral calculations, and not mechanical use. The oral account must prevail, supplement or enter into the part of the lesson he is subordinated. The manual can be used in mathematics lessons, as well as for independent work at home.
On our site you can download the book "3000 examples in mathematics. Oral account. Account in the range of 100. Grade 2" Pretorova Olga Vasilyevna, Nefedova Elena Alekseevna for free and without registration in FB2, RTF, EPUB, PDF, TXT format, read book online Or buy a book in the online store.

Long-awaited dance call -
The lesson begins.
Games, jokes, everything is for you!
For work, in good time!
II. Repetition of the studied material
1. Minutes of cleaning
Guys! Today we have an unusual lesson. I invite you to go on a sea trip to the Knowledge Country.
Throughout the trip, we will fix the skills of addition and subtract numbers within 100. We will travel on the ship (Slide 3)
You know that all travelers lead diaries of observations.
Your questionnaire will be your notebook in which you will lead all the necessary records. They must be clear and neat.
Be all diligent,
And the girl is attentive!
(Slide 4) - On the number of numbers - these are the rooms of the cabin. Write them down in the notebook in ascending order and you will learn the name of our ship. Check! Well done!
So, we went on a trip. We will sail for a long time, so I suggest you play in Domino.
2. (Slide 5)Game "Domino"
The guys are distributed cards, except one. Her teacher puts on a magnetic board. Students decide the example recorded on the card. The pupil should be released to the board, which in the left part of the card recorded the answer of the first example. He puts the card next to the first. A recorded example of the example is deciding all students, and the board comes to the board that the second example response on the left side is recorded on the left side of the card, and puts the card to the right of the second. The game continues until the chain of all cards is set on the stand on the specified rule above. The remaining students are controllers. They confirm or refute the responses of students leaving for the board.

Guys, see what beautiful birds are hired over the sea! What are their big wings!
Which bird has the biggest scope of wings?
Find the answer we will help the mathematical chain
It is necessary to solve it right. The answer of this chain will be a prompt
Cognitive minute:
“Albatrosse is sea birds. Most of the life they spend over the open sea or the ocean, beautifully gliding over the waves. They reach a length of up to 1.5 meters. Albatrosams have to fly very long distances, so the wingspan of them reach up to 4.5 meters. These birds have highly developed ability to plan flight. This bird can soar over the ocean of 6 days, without making a single waving wings. They have very long wings, so Albatrosse arrange their nestings, most often, on rocky islands, cool rising from the sea, or the ocean. "
