Fundraising is common in schools in Canada and the United States. Students, teachers and parents have many special ways to raise funds for field trips. Some schools have come up with good ideas, such as "King or Queen's Day". Each student must spend 1 USD to buy a lottery ticket. After all the tickets are sold out, draw a ticket. The holder of the ticket will be able to stop the king the next day or later. When students come to school the next day, they can sit in the principal's chair or even call home with the principal's mobile phone. At noon, the headmaster and other teachers will prepare a special lunch for the students.
