Technology lesson in 6th grade Theme of the lesson: "Quality of workpieces from a variety of rolled products" (first stage) amounted to: Teacher technology of the highest qualification category MKOU Svetloyarskaya SOSH No. 2 F. F. Plugnikova Trofimov V. P.

Objectives of the lesson to familiarize students with species, features of files of various purposes, with the principle of their work as cutting tools. Teach to determine the class of a file and its purpose.

Checking knowledge of students of previously studied educational material Check knowledge of students on the tasks cards of different levels of complexity (4-6 accounting). Answers to questions (other students): 1. From what major parts is a locksmithing hacksaw? 2. List the rules for safe work with a laminated hacksaw. 3. For what purpose on the workpiece at the scene do they do the triggered file? 4. How do the long blank cut?

Statement of new material: "Quality of blanks from a variety of rolled products" Qualification is cutting the workpiece of a small metal layer (cabin), with files to obtain the exact dimensions specified in the drawing. Files are made of instrumental steel.

During the classes

I. Repetition of the material passed.

1. Conversation on questions:

- What do you know alloys from non-ferrous metals?

- What are the properties of these metals?

- List the technological properties of metals and alloys.

- Name the mechanical properties of metals and alloys.

- Tell us about the use of aluminum.

2. Exercise on the development of observation, accuracy, accuracy.

The task. Determine which keyboard well the key is suitable.

3. Topics and lesson target.

II. Summary of software material.

1. Introductory conversation.

Teacher. In lessons in the 5th grade, we looked at a sheet rolled and wire. Remember how they get them.

For the manufacture of various products, other forms of rolled products are needed, which are obtained by rolling (compresses) of heated ingots between rolls of different profiles.

Often the form of the future part is close to the shape of a variety of rolled products, it allows you to reduce metal waste and the item manufacturing time.

There are various forms of varietal rolled products, the most common of them are presented in the figure. Consider and name them. (See Fig. 1.)

Fig. one. LORD PROFILES: but - square; b. - band; in - Hexagon; g. - a circle; d. - corner; e. - triangle; j. - Schweller; z. - Rail

The teacher explains the main areas of application of various rental profiles.

2. Practical task.

Sequence of execution:

1) Cut from tin two strips 100 × 240 mm and make experience, loading strips of tin (see Fig. 2).

Fig. 2. Sample strips of tin

2) load it is necessary to contact the strips of tinted with a table.

3) Write the data in the notebook and compare the results.

3. The result of the implementation of the practical task.

1) Assessment of the practical task of students.

2) generalization.

Teacher. In the section "Wood processing", we considered how diagonally depicted. Name these ways. ( Using sketches, technical drawings and drawings.)

How are the products from the rental? ( Products made of variety are depicted similarly.)

How are the product consisting of several parts depict? ( The product consisting of several parts is depicted on assembly drawings..) (See Fig. 3.)

What do corners do? ( Corner Control Template.) (See Fig. 4.)

III. Practical work.

Tasks:

1. Consider the rivet making device in Figure 3.

2. Make a sketch of the template in the notebook.

3. Carefully read the assembly drawing (Fig. 3) and fill in the table.

IV. The outcome of the lesson.

1. Check and comparing the data filled in the table.

2. Evaluation of sketches and tables.

Training technological card.

The purpose of the lesson:

Teaching : To form the concepts of varietal boxes and methods for obtaining it.

Developing : develop the logic of thinking, develop creative potential, skill

analyze, compare and make reasonable conclusions based on comparison.

Ripping : to raise interest in learning, educate hard work, accuracy,

preferabity, aesthetic feelings, sense of responsibility for their business.

Planned results:

Subject - Students get acquainted with assembly drawings, perform a sketch of details of one of the products, learn to read the assembly drawing of the product.

MetaPermet (UUD): Regulatory - convert a practical task into cognitive, communicative - the ability to work in a group when performing a task, the ability to conduct cooperation with the teacher, cognitive - what is the assembly drawing? In what cases in drawings are depicted not one species, and two or more? etc.

Personal - The ability to conduct the self-analysis of the work performed, the development of hard work and responsibility for the quality of its activities.

Basic concepts : Assembly drawing, reading assembly drawing.

Type of lesson: combined

Equipment : Samples of performed drawings, workbook, textbook, Checker accessories.

During the classes.

1. Stage motivation (self-determination to activities) - Org. Moment, we create a problem showing a slide with the image of the assembly drawing.

Question : Name the rules for the image of technical drawings, sketches and drawings of parts of wood and thin rolled steel.

What sizes are affixed in the drawings?

2. Actualization of knowledge and fixation of individual difficulties in the problem action.

In order to actualize knowledge, a brief conversation is carried out with students, during which the following questions are asked:

- In what cases in drawings are depicted not one species, and two or more?

(Cognitive URU - acquire new knowledge in the process of observation and reasoning)

What sizes are affixed on assembly drawings? (Regulatory Wood - independently read the assembly drawing);

(Cognitive Wood) -What is the assembly drawing?

In order to actualize knowledge, a conversation is carried out with students, during which the following questions are asked:

1. Why are assembly drawings of wood and metal products differ? (Cognitive URU - acquire new knowledge in the process of observation and reasoning)

2. Ask the order of reading the assembly drawing from a variety of rolled products (regulatory Wood - independently found in the textbook the necessary information)

3. What is the assembly drawing? What does the expression "overall dimensions" mean? (Cognitive Wood - to select the necessary information to solve the educational task, in the textbook, encyclopedia, Internet.)

3. Formulation of the lesson theme.

What do you think, we will learn today?

Finding out the opinion of children The teacher clarifies the role of drawing when designing products (actualization of students' knowledge, regulatory Wood - goaling)

4. Practical work.

The teacher organizes the actualization of ways to study the actions sufficient to build new knowledge.

Test action (task) - Consider Figure 61, follow the sketch of one of the details in the working notebook: screwdrivers. Template, corner-and sketch details from your creative project.

Experience: Stretch and release the springs from steel (tempered) and copper wire. Take the conclusion about the elasticity of steel and copper.

Read the assembly drawing depicted in Figure 62.

Fill in the table in the working notebook

The teacher verifies the correctness of the task, detecting difficulties in the trial action.

5. Fixing difficulties:

Incorrect definition of overall. Incorrect determination of the amount of species in the drawing (ways to solve the problem)

6. Exit from difficulty:

Once again, the teacher talks about the need for the ability to read assembly drawings, be able to perform drawings of individual details, thereby organizing students to explore the problem situation (Wood - Communicative, joint solutions to the problem)

7. Reflection of educational activities.

At this stage, summing up the lesson, the teacher asks children questions, responding to which he can judge the assimilation of this material.

Questions : What is the assembly drawing?

In what cases in drawings are depicted not one species, and two or more?

How do assembly drawings of wood products and metal differ?

What sizes are affixed on the assembly drawing?

What new knowledge did you get for yourself?

Can knowledge acquired today come in handy in life?

The teacher invites the boys to appreciate its work in the lesson. (Personal Uud - adequate understanding of the causes of success / not success in training activities.)

8. Cleaning jobs.
