Use these tickets as rewards for good students.
Students write their name or initials on the ticket.
They place it in the draw.
At the end of the day/week the teacher draws the lucky winners to get a small prize.
Print out on colour paper for the best look. Yellow or orange paper allows you to call them 'Golden Tickets' which gets the little ones excited. Cut into strips and then rip along the jagged lines.
This is really handy when teaching casually, especially with the junior years.
** UPDATE **
Now includes a sheet of blank tickets and various Raffle Ticket clip art so you can make your own.
