About mathematics, mathematics enlightenment, this is what I did.

I've always wanted to give this piece of mathematics enlightenment to my dad, because at that time, I got almost full marks (two points short) in the postgraduate mathematics exam and was killed in Jiaotong University. My math peak only appeared in the long drama of the college entrance examination 1 15. Unfortunately, my father is very busy at work and has been preparing for CFA exam. At this moment, I have the cheek to stand up and enlighten me while doing my homework. I'll start from the beginning ~

Judging from the inertia thinking of exam-oriented education in the past, of course, mathematics is to learn to count first. Since I was one year old and eight months old, I have consciously used my hand to index the plural objects in the picture book, adding units as much as possible when counting. For example, if you count apples on a tree, you can point and say 1 apple, 2 apples. The stress falls on numbers, so the processor in his brain will correspond to the connection between numbers and things. This operation can also be used in the same way when playing stack, but it can't be too utilitarian. Brother Hao likes to pile up high, but don't disturb him when piling up, it will destroy his concentration and attention. No matter how much he piles up in the end, I will say loudly: Wow! You piled up one floor, two floors, three floors and four floors. So high. You can't fall so high. You're great. After I don't count this repetition, he will count it himself. One day, when he pointed to a book and began to count the animals in the zoo, I realized that he had opened the door to numbers.

However, this carelessness will fall into a misunderstanding. The inertia of counting. After I was 2 years old, when I took him up the stairs, I observed that I could count to 30+, but he didn't understand and just kept counting down. Numbers with more than two digits are vague to Hao Ge. At the age of 2, I don't ask him to master such complexity.

After that, I began to transition to the enlightenment of mathematical thinking. That is, learning basic mathematical concepts. At the same time, the order of mathematics teaching in American kindergartens and the content of three-year-old mathematics enlightenment were investigated. I have to say that China students are very good at math, and they can master it when they are over 2 years old.

1, shape recognition. The beginning of cultivating geometric thinking.

This type of game is very easy to operate, and the building blocks are conducive to identifying objects. This was inadvertently mentioned when we piled wood before, and it was not deliberately strengthened. But Hao Ge has remembered. When he posted it, he told me it was a square, a rectangle and a triangle. Various puzzles in a treasure are also good exercise cognition.

2. Contrast. The basis of measurement.

Size and length are simple judgments of objects. This can be often enlightened in daily life without picture books and toys. Dad's feet are small, and mom's hands are small. The cartoon "Big Head Son and Small Head Dad" is also a good example. Vivid examples, understanding will help, advanced quickly. Two days ago, I took out a set of exercises for unified measurement and scientific thinking, and ran away the first time I spoke. It shows that it is still difficult for him to insist on speaking only one page at a time. I saw thinking in his eyes.

3. Match. The basis of learning rules.

Identify objects with the same characteristics and find out the differences. At first, it was also with the help of building blocks. A simple classification of colors and shapes. Starting from this, we began to observe many colors and species. A 2-year-old baby is actually very difficult, and it can't ruin interest or dampen confidence. Brother Hao is typical of impatience and impatience. He will make a hullabaloo about as long as he can't find it. Every time I ask him to find one, it is successful. I tell him that you are great. Hu Hui's 2-year-old enlightenment book, in which the pairing is different, is very young and can be reflected immediately after reading the topic. I use exercise books more in this training.

4. Compare quantities. Fundamentals of mathematical operations.

? Some people say that learning to count is the basis of mathematical operation, but I personally disagree. I think knowing the concept of quantity is the basis of mathematical operation. Less than 3 years old, there is no need to learn arithmetic. But counting, knowing who is more and who is less, can be mastered completely. It can also be operated in daily life. My mother ate two strawberries and one strawberry. Then who eats more? At first, I only compared the numbers within 3. Only the comparison within 10 is required before the age of 3. In the series of Maisy, which I have never tired of reading recently, there is a page "Maisy goes to kindergarten" with simple mathematical operations. I began to explain by hand on purpose. How many fingers are there now, two fingers plus 1 finger? How many fingers are left after removing three fingers? I accept it completely when I am in high spirits. But I reminded myself to stop, not to encourage others.

5. The concept of ordinal number. The foundation of logical thinking.

I have been committed to the enlightenment of ordinal numbers. Be careful when playing with toys. First take the barrels out from under the chute, then open the lid and take them out one by one. Finally, when not playing, put the building blocks back one by one and put them back in their original positions. This nonsense sounds a bit like a joke about how to put an elephant in the refrigerator, but it is the basis of logical thinking. We talk about it every time we go out. 1, eat a lot of rice; 2. Change clothes and pants; 3. Wear a hat and mask; Step 4 wear shoes. Ok, let's go ~ on the one hand, it is to let him understand the logic and order of doing things, on the other hand, it is also to avoid my bad habit of urging him to dawdle. The harder you push, the slower you walk. Isn't this a problem for us adults? Remind the implementation steps of the plan, but you can be an activist.

6. chronological order. The basis of causality.

I used to confuse ordinal number with chronological order, and then I realized it by applying it to causality. Because it is windy this morning, I can't go out to play. I will get sick if I go out to play. Because today is my birthday, I must make a cake before blowing out candles and eating during the day. Only in the evening can we go to Wu Xiaoyu's birthday party. This is what I deliberately said in the early days. Strong winds have happened before, and then we have to change our activities. On your birthday, list the activities in the morning, afternoon and evening one by one, and you will understand the order of doing things. I think this kind of thinking can be put into practice in the picture book immediately, so that he can master his own storytelling method.

Many of these careful machines and games in life were also inspired by my father. Thanks to my reliable teammates, they can also guide me in the dark.

I have always asked myself to learn one step faster than Brother Hao, and the rest we practice together and grow together. Next, I give myself the goals of enlightenment time cognition, addition and subtraction one by one (within 10), simple solid geometry, relative weight, long body, fat and thin, width, grouping and classification, etc.

It's a long way to go in Xiu Yuan. It's a never-too-old classic! Cheer yourself up!

Finally, I summed up my better exercise books and compared them with those with strong entertainment.

1, many tigers will have a whole brain

2. "Moby loves mathematics"

3. Magic Mathematics

4. Mathematical Strategy

5. The Book of Itsumi Taro and Thinking Games

6. American Preschool Workbook of General Practice
