1, thanks to the teacher's concern and education for the children. Parents must cooperate with the teacher and actively create conditions for the children to catch up with mathematics!

2. I am really sorry. Although my child has worked hard and made little progress these days, I and my child are confident, and he has set his own goals for the next progress!

3. Thank you for your concern. Children often talk about you when they come home, and never abandon a poor student like him. He is becoming more and more interested in learning mathematics!

4. Make persistent efforts, pay attention to details and learn to sum up yourself!

5. I didn't look at the questions carefully and didn't check them carefully.
