You can write down a few questions and let the children read them several times before each question.
Thirdly, let the children find out which is the corresponding mistake, and give encouragement if they answer correctly.
I don't practice much, but I work hard.
Tell the child to do it with heart. If we overcome an error-prone point, we will reward them for playing 10 minutes more. We don't need to do more questions. Time is earned by yourself. We just need to take it seriously. Give children the opportunity to correct their mistakes, encourage them more, and make them interested, not tired of learning.
