• The division is the division with a balance of 0, the number is divided = injury x division.
• The division with the main balance is always smaller than the division and greater than 0. Specifically the division number = Thuong x number divided + balance.

For example:

All division: 6: 3 = 2 excess 0

Division with excess: 7: 3 = 2 excess 1

Gold principle when doing division has a 3rd layer that your child needs to remember

First, the way to teach the 3rd grade mathematics with the excess of the baby is to conduct each division, based on the results and find the division with the same balance. This principle will help children review more about the results of a problem.

For example: 37: 2 = 18 (residual 1); 64: 5 = 12 (residual 4); 73: 8 = 9 (excess 1). Therefore, division 37: 2 and 73: 8 have the same balance of 1. From the division, the baby can easily synthesize the same balance.

A second form of math that children need to know is that the 3rd grade problem is hidden x or y. When solving hidden exercises, children must grasp the rule to find divided and find divisions. For example:

Y: 8 = 234 (excess 7)

⇔y = 234 x 8 + 7

⇔y = 1872

⇔y = 1879

This problem follows the principle:

• In order to find the divided number in the division, we take the trader and the division.
• If you want to find the divided number in the division with excess, after you love the division, we bring it plus the balance. In case the number is divided, then the spell is divided and constant.

In addition, parents need to grasp other basic principles such as: The division with balance is a division with a balance of 0 and the balance is always smaller than the division. Besides, children also need to learn the formulas when finding the divided or divided number and remember that the division is always greater than the division.

Teach your child the ability to focus when studying the 3rd grade math

At elementary school age, children are often giddy and very easily distracted. Therefore, teaching children the habit of focusing on childhood is extremely important, because when the child grows, that skill will help him learn better and work more productivity.

Here parents can diversify exercises by visual teaching methods, let their children rest after 20-30 minutes or have fun with children to make children feel more interested when doing homework.

How to teach mathematics to divide class 3 smart by thinking diagram

So how to help your baby acquire knowledge without being bored? It's just that you let your baby create colorful thinking diagrams in which the system has enough formulas. Besides, the way to learn through the frames in the diagram will support the child to do the homework and see the formula that increases the ability to memorize better.

With the calculation of 3rd class division, a baby can be divided into many different branches in the forms of exercises from which to practice according to each frame of the diagram, instead of chaotic learning will be easier to absorb and remember more .

Give your baby in contact with the forms of calculating the division with a 3rd layer to fit the child

If your baby always has to start from the difficult forms will make the baby discouraged and from there is boring in learning, he will be lazy and easy to be distracted. Therefore, choose the exercises that match your child's learning capacity.

Typically with the rule of division of class 3, parents should initially let the baby get used to the form of mathematics division with small numbers within 20. Division with 3rd layer residues is harder. Since then, the baby can easily understand, absorb knowledge and solve them correctly.

Instructions on how to divide class 3 for children will be extremely simple if parents grasp the formulas to help their children learn quickly and do the exercises properly. There have been too many methods of learning on the internet, timhieulichsuquancaugiay.edu.vn has helped parents synthesize the secrets to teach their children to learn division through two types of lessons for the baby below:

Form 1: How to find the divisor in the division with excess

Typically, for the division, we can find the division number by taking the divided number and all divided by the injury. With the very simple method in the following 3 steps:

• Step 1: We find the divided number and the balance according to the given problem.

• Step 2: Find the number divided by the formula: the division number = (the number is divided – the balance): Loving.

• Step 3: Perform the calculation and check the results.

Form 2: How to find the divided number in the division

To find the number of divided in the division, we take the number of divisions with the injury and all plus the balance. In words, it is easy to understand, please follow the following sequence:

• Step 1: Find the balance and the division according to the given problem.

• Step 2: Then find the number divided by the following formula: The number of divided = (the number of divided x) + the balance.

• Step 3: Calculate the answer, start checking the results and conduct conclusions.

Therefore, learning math will be extremely easy for children and children will be more active if parents know how to apply appropriate math solutions. In particular, if your baby has difficulty in the solution, instead of parents giving the answer to their children, let them have the opportunity to find solutions themselves. And that is the best way to teach mathematics class 3 that you should apply immediately.

Some common types of math exercises

In order for children to study in 3rd grade mathematics with two -digit numbers for one -digit numbers through the above methods, parents can refer to some common math exercises to help children easily visualize below. Here.

Basic exercise

In this form, your baby will be familiar with the division of two to three digits and have excess. Through the following exercises, children can easily master the division without using the formula. Specifically as follows:

• 64: 7 = 9 (excess 1)

• 234: 17 = 13 (residual 13)

• 98: 15 = 6 (excess 8)

The form of mathematics is hidden x, y

Not only appears in the way of teaching division with 3rd layer, the type of mathematics is hidden x will appear a lot in mathematics in large layers. Therefore, you should let your baby get used to the hidden way based on the rules of the division or the divided number presented above to calculate accurately.

For example:

Apply the formula: Find the division number = (number of divided x) + balance

We have: y = (7 x 5) + 2 = 37

Apply the formula: Find the division number = (the number of divided – balances): Trade

We have: y = (55 – 6): 7 = 7

For advanced math types

If your baby has absorbed the two types well, you should lead your child to the 3rd layer division calculations to create a thinking for him to learn math. However, in these forms, parents should not ask for too much to avoid putting pressure on the baby.

Solution steps:

• Step 1: Need to find the divisible number and balance.
• Step 2: Continue to find the division number that: the division = (the number is divided – the balance): Loving.

For example, find the y in division with the largest number of 2 -digit, 6 -digit and the balance will be less than 3 units.

The solution is as follows: According to the topic, the number of divided is the largest number, so the number 99. Thuong is 6 and the poor balance of 3 units should be: 6 – 3 = 3. So the division is (99 – 3) : 6 = 16.
