Let's make a plan for our work in the lesson, for this we remember similar lessons on working with the multiplication and division tables.

Let's remember what properties of multiplication we will need when working

Why don't the answers change?

What knowledge do we need when compiling a division table?

What will we do when we create the table?

Based on your answers, here is the work plan (Slide 15)

First we will make a multiplication table. To do this, we will count by 5 and write down the answers, they will help us not to make mistakes, and then we will swap the factors and the answers will be the same.

We know that rearranging the factors does not change the product.

When doing division, we remember that division is related to multiplication.

And then we will apply it, solve examples and problems and memorize the table.

Primary performance of the task with pronunciation.

Work in pairs for mutual checking

1) Who is the most attentive

What if it's 15? what if 25?40? And if 18 then it will be divided equally? Why?

Now let’s try to solve the examples themselves using the knowledge we have received.

2Task 2 p. 23;

We will pronounce columns 1 and 2, and

3 we will carry out independently with mutual verification

By 5 (list animals)

By 3 (15:3=25); by 5 (25:5=5), by 8 (40:5=8)

18 is not divisible by 5, which means it won’t be equal.

children take turns completing the task, saying the answers, checking the table

Assessment on the score sheet

Ability to apply your knowledge in a non-standard form (P)

Primary application of acquired knowledge, (P).

Situation analysis(R)

Application of acquired knowledge in practice (P)

Conduct mutual verification (R) and evaluate their activities

8. Inclusion in the knowledge system.

Target:

Solving equations (No. 3 p. 23).

the standard is given individually, because the pace of solving is different for children

Solving problems No. 5

Work in pairs

When solving equations, we need to remember the names of the components and their relationships.

In which equation will you search by multiplication? And in what division?

If we remember how to solve equations, it will not be difficult to solve them.

Now let's move on to solving problems. Read task No. 5 and complete the diagram with data.

Let's create a diagram for the problem:

Red green

_______________!_____________

We often encountered such tasks, test your strength and work in pairs. Whose pair finishes first will demonstrate their solution on the board

And you can write this decision as an expression. Who will help?

When multiplying: factors, and the result is a product. When dividing: dividend, divisor, result-quotient. The multiplier is found by dividing the product by a known factor. Divisor too

we find by division, and we find the dividend by multiplication.

Independent work.

Checking the assessment on the score sheet

Read the problem.

Drawing up a diagram on the board, checking the correctness of filling,

decide in pairs

The solution is shown by the first pair at the board explaining:

Repeat the names of the components and their relationship (P) include new knowledge with previously learned

    Work on the topic of the lesson

    Working from the textbook

Guys, who can tell me how to find a number that is several times smaller than a given one? (by division)

Read task 1. What do you think “3 times less” means? (number divided by 3)

Read task 2. What does “3 times less” mean? (Subtract 3 from the number)

    Working on a task (one student working at the board)

Igor has 18 candies, and Sasha has three times less. How many candies does Sasha have?

Solution: 18: 3 = 6(k.) Sasha had

Answer: Sasha has 6 candies

    Physical education minute

Two - bend over, pull up.

Three - clap 3 hands.

By four – your arms are wider.

Five - wave your arms.

Six - sit quietly at your desk.

    Problems in verse. Children write answers in notebooks

8 couples dance the polka

How many dancers are there? (16)

Grandma baked for us

Delicious pancakes.

There are 27 pancakes in total.

    Learning new material. Compiling multiplication and division tables with the number 5.

The board is divided into 4 parts. Invite 4 students to the board, the teacher gives each a task.

– Today in class we must make multiplication and division tables with the number 5.

1st column: Multiplication table for the number 5.

2nd column: Using the commutative property of the multiplication action, create a multiplication table for the number 5.

3rd column: Using the multiplication table for the number 5, write down how to get the first factor.

4th column: Write down how to get the second factor.

Checking and analyzing the table.

In a product, the units place is 0 or 5.

If we multiply 5 by an even number, we get a round number.

If we multiply 5 by an odd number, then the last digit of the product is 5.

If we multiply 5 by an even number, then the number of tens is equal to half of the second factor.

If 5 is multiplied by an odd number, then the number of tens is equal to half the number preceding the second factor.

    Consolidating multiplication and division tables with the number 5

    Game “Eye - photographer”.

– In this game we will check who has an eye like a camera, i.e. who can take a picture of the table (remember it). Then those who wish will go to the board, all other children will ask questions on the table.

    The solution of the problem. Fill the table.

How many steps are there to solve a problem? (Two.)

What will you learn in the first activity? (Total fabric consumption.)

What will you learn in the second act? (Fabric consumption per coat.)

Write down the solution and answer to the problem. (Examination.)

    Working from the textbook

(Independent execution. Check.)

What rule did you use to solve the problem? (To find out how much one number is greater or less than another, you need to subtract the smaller number from the larger number.)

(Independent execution. Check using the sample.)

Fill in the magic square in the fields.

(Examination.)

Give the sum of the square. (78.)

Read the numbers in the middle line. (24, 26, 28.)

Read the numbers on the top line. (25, 30, 23.)

    Reflection

    Game “I’m going to visit.”

Children are divided into guests and hosts. The owners sit at their desks, they have sorbon cards on which examples of table multiplication and division are written, and with reverse side answer. Guests approach any host, who gives them a card. If the guest correctly names the answer, then he takes this card with him and goes to another owner. Whoever has the most cards wins.

The game starts and ends at a signal.

    Game “Class Record”.

– Write down 15 equalities for table multiplication and division with the number 4; whoever writes it down first goes to the board.
