      Children, your parents will come to our school at nine o'clock in the morning. I'll meet them at the school gate. First, I'll take the parents to the classroom. They will look at the homework and projects on the board. Next, they will go to the hall.You will sing four songs and act a short play for the parents. Then they'll go to the art room. You will show your parents some beautiful pictures. Finally, they'll have tea and cakes with the teachers in the meeting room. We'll talk to each other.
