Where can I buy a large edition of calligraphy for first-grade pupils?

Hehe, personally, I think it is better to draw red copybooks. In fact, there is no need to ask too much at such a young age. Being able to maintain interest is the greatest success. I also attend training courses. If children of this grade come to me, I only have a few requests. The first is to try to be horizontal and vertical, and the font width and length are different. The second is not to hate practicing calligraphy, the third is to try to write in the middle of the grid, and the fourth is to know that the strokes are light and slow.
