I've seen it and I'm still watching it. Generally speaking, this textbook is relatively good compared with other textbooks. Very easy to understand. The introduction has theories, examples and methods. If you don't know much about early education and want to teach your children early education, you can use this textbook. But I don't know why there are typos in genuine textbooks. I asked Grandpa Feng, and they also said it was a misprint. Fortunately, this is not for children. The most important thing to remind you is that it depends on whether you can persist. I am a patient person. When you are in a good mood, you can use the method of teaching materials for a while, and the children also perform well. But when I'm in a bad mood, I get angry with my children. This is also the most taboo, but there is no way. According to the teacher, getting angry with a child often will have a great influence on his character development. My advice to you is to consult before buying. Tell the teacher about your child and see if it is suitable. I recommend you to go to online Budai. You can consult at ordinary times without buying textbooks. It's quite applicable.
