Math 2 Lesson: Division 2

### 1.1. Knowledge to remember

– Table of dividing numbers by 2 and related word problems.

### 1.2. Math forms

**Form 1: Calculate**

To calculate the value of division, you need to repeat the division table you just learned or do the multiplication.

**Form 2: Math quizzes**

– Read and analyze the problem: The math form shows the value of many groups, the number of groups, knowing the value of each group is the same, asking to find the value of each group.

– Find the solution: I take the value of many given groups divided by the number of groups.

– Presentation of the article.

– Check the solution of the problem and expand the problem (if any)

### 1.3. Solving Textbook Exercises

**Lesson 1**

Mental arithmetic:

6 : 2 = 2 : 2 = 20 : 2 =

4 : 2 = 8 : 2 = 14 : 2 =

10 : 2 = 12 : 2 = 18 : 2 =

16 : 2 =

__Solution method__

Review the table of division by 2 you just learned and fill in the blanks with the results.

__Solution guide__

6 : 2 = 3 2 : 2 = 1 20 : 2 = 10

4 : 2 = 2 8 : 2 = 4 14 : 2 = 7

10 : 2 = 5 12 : 2 = 6 18 : 2 = 9

16 : 2 = 8

**Lesson 2**

There are 12 candies divided equally between 2 friends. How many candies did each of you get?

__Solution method__

To find the solution, we take 12 candies and divide by 2.

__Solution guide__

The number of candies each friend is divided is:

12 : 2 = 6 (candy)

Answer: 6 candies.

**lesson 3**

Each number 4, 6, 7, 8, 10 is the result of which calculation?

__Solution method__

Mentally calculate the values of the given calculations and then connect to the cell containing the corresponding results.

__Solution guide__

Doing the division calculation we get:

12 : 2 = 6

8: 2 = 4

20 : 2 = 10

16 : 2 = 8

14 : 2 = 7

Join the cell containing the calculation with the cell containing the corresponding result, we get:
