It is necessary to reward children for their efforts in practicing calligraphy and let them enjoy practicing calligraphy. The more dedicated children are, the more encouragement and rewards they should receive. If the child gets a reward on the first day and practices calligraphy consciously the next day, he should give the child a hug and practice calligraphy with him. Then, if the children continue to practice calligraphy in the third grade, they can take them out to play after practicing calligraphy.
Only parents will be willing to practice calligraphy with their children, because parents are their children's first teachers, their most trusted people and their first playmates and friends. Therefore, what you want to do with your child, the child will be willing to do it and will do it better. Because parents like it, it will also be affected, and they will like to practice writing.
Write with your child regularly, and then let the child show his font in front of other family members, so that the child can be praised and affirmed. This exhibition will make them more firmly like this hobby, have a stronger interest in writing, make them more proud of what they have done, and make them more confident and determined to practice calligraphy.
That's what I do to my children. Children nowadays don't need adult supervision. They consciously practice calligraphy every day, and they are very pleased to see it. For pre-school children, I recommend a calligraphy practice tool that my children are also using, called the Three Treasures of Calligraphy. This tool allows children to practice hard pen and soft pen calligraphy. Very practical. My children have used it for more than a year, and the effect is still very satisfactory. You can check it online. I hope it is useful to you, and I hope it will be adopted!
