If your child is under three years old, and you want your child to receive the training of thinking ability in advance, I suggest you buy the theme book of the first stage of "Logic Dog" for your child to try out and test whether it is acceptable to your child. If you feel that there is no problem, you can follow the parents' guidance and guide your child to learn step by step. If the child has difficulty in operation, don't rush to let the child touch the card, and pay more attention to cultivating the child's ability in life. When the child's abilities in all aspects are improved, it will be more effective to let him learn "logic dogs". In addition, many two-and-a-half-year-old children we contact are using "logic dogs", and the effect is very ideal. I believe your baby will grow up happily with the company of "logic dog"! PS: My baby is two and a half years old. The following are some experiences of my baby in the process of being a logic dog. I hope I can share it with you. This is what I wrote before. I lost this family version of Logic Dog six months ago, and the seller 370 yuan guaranteed it on Taobao. To tell the truth, I'd rather lose my book for my son. I really have no confidence in buying a set of books by investing so much at one time. Moreover, although the comments of some mom forums are more favorable than unfavorable, some moms are not very satisfied. However, my husband and wife are both gentle and reasonable. From the perspective of winter and winter, the language ability is quite strong, and counting and the like have been relatively poor. I hope that through this training, I can cultivate his logical thinking ability and abstract thinking ability from an early age. There is a sentence in the introduction that touched me. "It is better to teach people to fish than to teach people to fish." I was quite surprised when I came back from the post office. What a heavy box. When I lost for the first time, my son was only two and a half weeks old. I didn't read the discs in the box or the textbooks used by parents, so I took out the first issue of Lisa and Tam series and tried it in winter and winter. Winter and winter, the first stage of mind gymnastics has been done for some time, and some of them are doing well. But logic dogs are obviously much more difficult, especially on the first and second sides. With my help and analysis, it was successfully completed. Thirdly, it refused to do it again. It is estimated that it is really difficult at this time. He is often praised by adults when he does "mind gymnastics". Now that he has done it, he can't find the right party for a long time, and he is very frustrated. I guess it's my age. So I put all the teaching materials and teaching AIDS in boxes and stuffed them under the sofa for half a year. Last month, after my third birthday, I took out the first stage of this textbook and carefully read the parents' guide. I started to do something off and on. Because I usually live at my grandmother's house in winter and winter, I will pick it up on weekends. So I usually review what I did last week every day on weekends and then do it on both sides. Do three things at the same time with the new and the old. For more than a month, Lisa and Tam have just finished winter and winter, and their colors and shapes have been made several times. The reverse side basically didn't move, because his painting was so ugly that he couldn't bear to let him scribble on the book, so he copied some on the back and asked him to scribble on the copy at will. This move is really necessary, because the copy is also very messy. I took some photos on the back. As far as the topic is concerned, the three-year-old baby is a little hard, and it depends entirely on the guidance of adults to make him understand and be interested in doing it. In particular, Cary's games should be three-dimensional and more in touch with real life. These not only help him understand, but also keep his interest in doing the problem. Don't let him feel that this is a burden. Dongdong didn't quite understand the intention of the topic before doing such a topic, so I asked him to look for cotton slippers at home. What are dad's slippers, mom's slippers, his slippers, the quilts and pillows in mom and dad's house, and grandma's room? After playing supporting games at home, I can do this problem quite quickly. Another example is this page. At first, there was nothing to talk about in winter and winter, and I couldn't find a suitable figure. So this page was put aside. Next, I used DC to take photos of everyone in my family, including teddy bears and Pippi bears in winter and winter, and put them on the computer to let him find out whose front and whose back. Looking for his family and friends, of course, was not in vain, and he was very interested. He came and went and found the difference and connection between the front and the back. It will be much easier to do this page next time. For example, here, it is more interesting to do. After finding the corresponding shape, I posed with him on the bed in the room. My son had a good time, and then he forced his father to make it for him. Whether there is improvement after completion is definitely not obvious in the short term, but winter and winter are small classes before the next month, and the school uses Montessori textbooks. I think his homework is as simple as eating rice. But there are still many weak tendons in winter and winter, which may be due to personality or age. Some topics are backward, well done and advanced according to the degree of difficulty, but they are not. For example, these two pages show that the difficulty of compiling textbooks cannot be generalized, and children still have individual differences. In fact, I think these circles are also dizzy. The problem of walking the maze in winter and winter has always been bad. Some mothers always ask me how I am. I still find this question difficult to answer. In fact, these textbooks that have been tested by time and experts have their own advantages. You can book a set if you can (I mainly mean time and energy). Actually, I don't want to buy it either. I think some of our usual magazines and books, and some school textbooks, such as Montessori, The First Starting Line and Mind Gymnastics, are all involved. Maybe this kind of books also learn from each other when editing.
