This book is very thin, but I have read it several times, and every time I read it, I get different results. I first read it after I got the book. The only feeling is, oh, I can help my children learn math from painting. The second time I saw it was during the winter vacation. At that time, I happened to be reciting the second volume of the first grade and found that many of them were painting parts.

It's like seeing if there's anything worth learning. I found this book really a treasure. For our new teacher, it made me understand that students' understanding can be improved through painting teaching. I read it carefully the third time. Every time I see a wonderful part, I write it down and save it in my mobile phone. Think twice, why do students draw like this? What are the advantages of drawing in this way? How should I study? Therefore, in the process of "trying" in the library, the "line chart" was intentionally introduced (starting from the simplest), and the "drawing a circle" in the book was further introduced into the "line chart". Some students said that the line graph reflects the quantitative relationship more intuitively than drawing a circle. I think, even if some children can't understand the benefits of line drawing now, at least another part can feel its benefits and make proper use of it. I think it's really great to let children learn math in painting! (Line drawing in the attached book)
