Good morning, the day has begun,

First of all, we drive away laziness,

Don't yawn in class

And work and write!

“Now we looked at each other, smiled, took a deep breath, and exhaled. They sat down quietly. Let's start the lesson!

II. Communicate the topic and objectives of the lesson.

TECHNOLOGICAL MAP OF A FRAGMENT OF A MATHEMATICS LESSON

Full name of the participant Daria Andreevna Ustinova

Lesson topic: “Dividing three-digit numbers by single-digit numbers”

Class: 3

The purpose of the lesson fragment is to create conditions for students to become familiar with the algorithm for dividing three-digit numbers by single-digit numbers and learn how to apply it in the lesson

Lesson fragment objectives:

Didactic: learn the written method of dividing a three-digit number by a single-digit number, determine the written method of dividing a multi-digit number by a single-digit number and justify your opinion; organize student planning activities together with the teacher to study or review a new topic, consolidate the skill of writing division of three-digit numbers into single-digit ones.

Developmental: find and read information presented in different ways (textbook, reference book, audio or video materials).

develop logical thinking, memory, mathematical knowledge and skills; accept and maintain the goal and learning task; cooperate with peers and teacher.

Educational: cultivate a positive attitude towards the subject “Mathematics”, participate in conversations, various activities, exercise mutual control and provide the necessary mutual assistance in cooperation; manifestation of motivation for educational and cognitive activity and the personal meaning of learning.

On the tables are a textbook, a lined notebook, and a pencil case. We sit straight, legs together.

Guys, I have a rebus on the board, who knows what word is hidden here?

True, but why do we need mathematics?

Checking readiness for the lesson. Greetings.

Identifying difficulties: what is the complexity of the new material, what exactly creates the problem, searching for contradictions Organizing an analysis by students of the situation that has arisen and, on this basis, identifying the places and causes of the difficulty is an awareness of what exactly is the insufficiency of their knowledge, skills or abilities. Verbal (conversation) That's right, what other numbers are there?

And after two-digit ones, what numbers come next? What numbers can we divide three-digit numbers into?

How is a three-digit number divided by a single-digit number?

Single-digit, two-digit, three-digit and multi-digit. Three-digit

Single-digit, two-digit, three-digit

Development of a project, a plan to resolve their existing difficulties, consideration of many options, search for the optimal solution setting goals for educational activities and, on this basis, choosing the method and means of their implementation. Verbal (conversation) What do you think is the topic of our lesson?

What goal can we set?

Let's make a lesson plan.

Dividing three-digit numbers by one-digit numbers.

Learn to divide a three-digit number by a single-digit number, learn the division algorithm.

Make a plan.

F Presentation Control organize student planning activities together with the teacher to study or review a new topic. develop logical thinking, memory, mathematical knowledge and skills; accept and maintain the goal and learning task; cooperate with peers and teacher. participate in conversations, provide necessary mutual assistance in cooperation
Implementation of the chosen plan to resolve the difficulty. This is the main stage of the lesson, where the “discovery” of new knowledge occurs the construction by students of a new method of action and the formation of the skills to apply it both when solving a problem that caused difficulty, and when solving problems of this class or type in general. Verbal (conversation)

Visual (demonstration)

Let's turn to the first point of the plan (learn the division algorithm). Find in the textbook on page 93 how you can divide a three-digit number by a single-digit number in writing. Let's look at it using the example of dividing the number 748 by 2 (on the board). First of all, we divide hundreds, there are only 7 hundreds. That is, we divide 7 by 2, the quotient will be 3, since 3 * 2 = 6, after that we subtract 6 from 7, we get 1 hundred, the next step is dividing tens, we For our 1 hundred we rewrite the number 4, that is, 4 tens, we get the number 14, we divide it by 2, write it as the quotient 7, then 7*2=14, divide 14 tens. Subtract 14 from 14, we get 0. There is no remainder. The units were all divided.

What was the answer?

We have implemented the first point of our plan.

Open the textbook and analyze the algorithm using the example presented on the blackboard.

Answer: 374
