How to teach children to compare the size of numbers, how to teach children to grasp the size of num

Hello, you can prepare 20 number cards, the shape is a circle (from small to large) The shape increases with the size of the number, so that children have a clear feeling, easy to teach and easy to learn.

Kindergarten Kindergarten Math Lesson Plan: Compare the size of numbers.

Objective: Be able to correctly determine the number of numbers within 7.

Preparation 1. 5 large blue discs of velvet, 6 red discs from large to small, and 7 small orange discs.

2. Velvet number, physical card.

The process of the activity. 1. Group activities.

1. Show ** one by one.

Ask the children to look carefully and tell me how many things are on the card.

2. Correctly judge the quantity within 7.

Show Figure 1. 1) What's on the blackboard? Which color has the most discs? Which color has the fewest discs? How do you know?

2) Why do I think I have the most red discs and the least orange discs when I look at it?

3) Who can think of a way, another way to make it clear at a glance, who has the most number and who has the least.

4) Inspire toddlers to line up each color piece and see who has the most and who has the least. You can see it from **. Guide the children to compare the three rows of discs one by one) Ask the children to tell how many discs there are in each row, and who will send digital friends to each row of discs.

3. Summary. If you want to know who has more and who has less, you can't look at the size of the object, nor can you look at the length or length of the queue. Instead, you have to count how many there are in each row to see who has more and who has less.

2. Group activities.

1. Print numbers for the most pips.

2. Look at the markers and paste graphics.

3. Fill in the blanks in order.

4. Add and remove ideas.

5. Printing less ideas.

When teaching children how to count, the key is to tell them that "when counting, the number that comes behind is greater than the number that comes before it." For example, a parent can say to a toddler:

2 is behind 1, 2 is bigger than 1, 3 is behind 2, 3 is ...... bigger than 2"It should be noted here that it is easy for young children to grasp the concept of size, and the concept of big and small should not be taught at the same time, but after mastering one of them, the other should be taught. If you tell your toddler so;

2 to 1 is bigger, which is 1 to 2 smaller. "It's hard for toddlers to tell the difference. And once the child understands the meaning of the sentence "When counting, the following number is greater than the previous number", then tell the child:

The number in the front is smaller than the number in the back, "so that the toddler can firmly grasp the relationship between the size of the numbers." After the child has mastered the relationship between the size of the number, the parent can teach the composition of the number. To teach children the composition of numbers, it is still necessary to use physical objects, and the method steps are as follows:

First, ask the child to count 3 candies and put them on a plate, and then, take 3 more empty plates and ask the child:

Put the same amount of sugar in each plate, how many in each plate? "At this time, toddlers should put 1 candy in each plate. After the toddler has finished dividing, the parent asks the toddler to put 3 candies on two plates.

Toddlers should put 1 in one dish and 2 in the other. After several such "sugar separation" training, children begin to have a certain concept of decomposition and composition. At this time, parents can use numbers to train their children to master the composition of numbers.

Parents tell their children that 3 candies can be divided into three candies, that is, "3" can be divided into three "1s"; 3 sugars can also be divided into one two sugars and one candy, i.e. "3" can be divided into one "2" and one "1". Parents should write down the numbers and explain them to the children while they are writing.

Finally, teach the toddler that each number can be divided into several smaller numbers. Parents can give any number from 1 to 10 for children to try to break down until they are proficient.

1. Subtract.

2. Use it to see when the positive number is used.

3. When the negative sign is negative, the absolute value is small and large.

4. If the same number is positive, both sides are squared, compare the size (for irrational numbers) 5, divide or multiply by an identical number, and make a comparison.

6. For example, 702, 306, look at the number of the highest digits.

There are a lot of them on the Internet, so look for yourself.

Hello, the size of the comparison number is generally compared from the high position, which high number is larger, which number is larger.

Of course, to compare the size of the decimals, we first compare the integer part, which is the larger part of the integer, and which decimal is larger. If the integer part is the same, it is greater than the decile, and the decimal number on the tenth digit is larger, and the comparison in turn, not the same as the integer comparison, first see which number has more digits.

Hope it helps, if you have doubts, please keep "following up"!
