How to teach vertical division?

1, understand the basic concept of vertical division.

Before teaching children vertical division, we need to let them know the basic concept of vertical division. Vertical division is a method to express the division process vertically, which can help us understand the division process more intuitively. By learning vertical division, children can better grasp the law of division operation and improve the calculation speed and accuracy.

2. Teach the method of vertical division step by step.

When teaching children vertical division, you can start with a simple one-digit division. For example, children should be taught to calculate the vertical division of 12÷3. First of all, let the children understand that the dividend is 12 and the divisor is 3. Then, let the children learn to divide the dividend into several parts, and each part contains a divisor.

In this example, we can divide 12 into two parts, 10 and 2, where 10 contains a divisor 3. Next, let the children learn to calculate how many divisors each part contains. In this example, 10 contains three divisors 3. Finally, let children learn to add up the results of each part to get the final quotient. In this example, 10×3=30 and 2×3=6, so 12÷3=4.

3. Encourage children to do more exercise and cultivate their self-confidence.

In the process of tutoring children to learn vertical division, we should encourage them to do more exercises and cultivate their self-confidence. We can prepare some interesting exercises for children, so that they can feel the fun of mathematics in the process of completing the exercises. At the same time, we should pay attention to children's learning progress, give timely encouragement and support, and help children build self-confidence.

How to teach vertical division in grade three? I believe everyone has a certain understanding! It is an important task to help children learn vertical division in grade three. Teaching operation methods step by step, consolidating operation ability through examples and encouraging children to do more exercises can help children master this math skill easily and lay a solid foundation for their learning and growth. I hope my sharing will help you, and I wish your children academic progress!
