2016-07-03, 23:18:50

Didactic goal: to create conditions for the child tasks and their logical parts, the ability to distinguish them from arbitrary texts.
Type of the lesson: the discovery of new knowledge.
Lesson objectives:
Theme: shaping the ability to solve simple problems to find the part and the whole, record their solutions, draw the graphic scheme for these tasks and to complete assignments.
Interdisciplinary:
Personal data:
to create conditions for the formation of ideas about the causes of academic success,
a positive attitude towards studying mathematics.
Regulatory:
create the ability to understand guides teacher actions in the learning material
- evaluate together with the teacher and classmates the results of their actions, to make appropriate adjustments under the guidance of a teacher
Informative:
independently select a basis of classification, to find different grounds for the classification to sort objects into groups by a selected characteristic compare
Communications:
to adequately use verbal means to communicate in the classroom,
to formulate an opinion,
to accept different points of view.
Teaching methods: the method productive.
Forms of organization of cognitive activity of students: the collective, steam-room.
Goal: to create motivation for learning activities in the classroom by maintaining in them faith in their own strength;
to determine the substantive scope of the lesson: introduction to a new mathematical problem;
to consolidate understanding of the concept of "training".
The teacher opens on the Board quatrain:
In school we came to learn,
In life is to be useful!
Anyone who wants to know a lot
Must understand!
Do you agree with its contents?
As you know that the doctrine is useful in life?
Soon, soon the New year
Visit us again will come,
To bring fun, laughter,
And good luck, and success.
The word "he", how do we know when we all understand that we don't know and open yourself to new knowledge.
We need to do two things: to understand that we don't know know about that
Actualization of knowledge and fixing individual difficulties in the trial action.
Practice computational skills.
Mery: Wow. What? Again comes the New year. And we have no trees, no toys, Teddy and sleeps again. How to Wake him up? Maybe the alarm. But where is he? Buddy, help me find an alarm clock.
-Will help you, guys?
The children are encouraged to perform mental calculations:
bear: Mery, what happened? Why such a ringing?
Mary: Mike, how? Of course, You are not forgotten. The New year is coming. And we even have a tree. And where to take it I'll never know.
bear: Mery, I have an idea: let's dress up now this is no ordinary tree, and the tree of success.
The actualization of the relationship of part and whole.
-Guys, what can you say about these numbers?
-What tasks can you offer?
Mery: Oh-e-e - e, as healthy. Yes, I want a Christmas tree. Bear, let's go into the woods.
Bear: no, mashunya, this tree in our forest no. It grows only in the country of knowledge, but the way back was long.
To compile the template expression.
Masha: Oh, and who else? Pious in the morning. And who are you? Who is here?
Snowman: I Snegovichok, friend and helper of Santa Claus. We found out about Your wish and decided to help you. Sends you, Mary, letter to Santa Claus.
Trial action.
Open the envelopes, remove the job.
What's new for you in this job?
What is the goal You set for yourself in class?
What do you think the theme of today's lesson?
Students perform the task.
So, let's see what you got.
Who can do this job?
Students read the texts consist of tasks.
We were at the beginning of the problem.
To learn how to perform tasks
Task, the solution of the problem.
We can't make the call
We can't justify their results
To understand what the difficulty is
Identifying locations and causes difficulties.
Goal:
to identify and describe the location and cause of obstruction. What task did you perform?
This problem differs from the previous one?
What's the difficulty?
Why is there a difficulty? We had to do the job.
We were not tasks
Build the project the way out of difficulty.
Goal:
to create difficulties for the project: the aim of the project, to determine the means to formulate a step achieve your goal.
What is the purpose of the future work?
You can help. What task you perform a repetition?
As this task can help?
How can you know what's the problem? To build a test that is part of the problem
We have collected the pattern expression.
Implementation of the constructed project.
I suggest you work in pairs. What are the basic rules work. Follow the plan in pairs.
As presented in the problem?
What do you think, what cards should start doing the task?
Students select the condition card.
To read the text written on the card.
What's the map like? (Proteins 4 nuts.)
Why you choose this card?
Teacher hangs on the Board the cards with the condition.
All we know is a state.
What to do with this condition? What should be the next map?
To find this card. To read the text.
You need to find is the question.
How many pieces should be in the text of a task?
Name them?
Further work is organized rack.
You coped with the task to repeat?
What helped?
If we can make a drawing to the task?
We offer you to perform the task in the diagram.
To build a diagram for this problem. What you have built to solve the problem?
The teacher puts on the Board the corresponding card.
How to solve this problem? With the help of action?
Justify Your answer.
Make a expression to solve this problem.
The expression fixed on the Board and students book.
What did you do to solve the problem?
The teacher puts on the Board the corresponding card.
To find its value?
The resulting equality is called a solution of the problem.
The teacher post the relevant cards on the Board.
So, you have already solved the problem?
Read the question task.
One of the students reads the question to the problem.
To answer the question.
Write down the answer.
Since you are a complete solution to the problem?
To draw a conclusion. What parts of the task?
What helps you to solve the problem?
To check our conclusion.
What conclusion can you make?
Could you overcome the difficulty?
That will allow you to access?
What is the next step in the lesson?
Snowman: well done, guys. Coped with the task. Relax.
The P. T. Break "The Snowmen"
Everyone has the right to speak, others should listen. The pair must work so as not to disturb other couples.
In the template
Proteins have 4 nuts and 2 cones.
Squirrels have 4 nuts.
To this text we can put the question. Should be the question
Condition and question.
The diagram at Fig.
Using the operations of addition
We are looking for a whole to find the whole need to put the pieces
The expression
We made the right opening
Now we can create tasks and to solve them.
To consolidate new knowledge.
Initial consolidation of external speech.
Mary: Teddy bear, Teddy Bear, soon we'll get to the tree?
Bear: complete the task and I will tell you.
1) No. 2, p. 44.
2) Work in pairs.
Issue 3 page 44
Find the number 3 on this page. What do you see?
Do you think that you need to do?
To do the task. What is the scheme?
What composed expression? Why?
What else do you go?
And how to make sure that you understand well and not make mistakes?
Problem solved
To call part of the problem
One plate of 5 apples and 2 apples. How many apples on two plates?
Cut divided into parts
We are looking for the one part to fold
You need to perform independent work regulatory: control, correction and knowledge already learned, and what remains in the absorption,
Independent work with self-test according to the standard.
No. 4, p. 45.
The task is done to the front.
The solution of this task in the textbook and Highlight all parts of the task.
To check it out.
Anyone have error? What are they? (Students call their mistakes.)
To draw a conclusion.
Where it is possible to do this? (Homework.)
Who has no mistakes? To draw a conclusion.
We need to practice selecting parts of tasks and to solve problems.
Inclusion in the system of knowledge and repetition.
Find number # 5 on page 45.
Looking for all the parts folded.
4 yellow circle
3 red triangle
Looking for an unknown part, subtract the known part.
9 blue circles
2 standard blue circle: control, correction and knowledge already learned, and what remains in the absorption,
What is the goal You set for yourself?
If you have reached your goal?
What a discovery you made in class?
Mike: well done, Mery and the guys coped with the task. And now you know: the tree of success at everyone.
Tree of success is your desire and opportunity. Thanks to each of you, we managed to find this tree. And now their hands will create a tree of success that he was always around and helped us to overcome difficulties.
Each child on the table part of the tree. Together with the teacher running the application "tree of success". To build a standard task.
