Fold this in half and add to the top of a small ziplock bag as a little way to celebrate 100 days at school.
Inside the bag place 1 long shaped cookie (eg scotch finger, or tim tam), and 2 round cookies (lots of these types to choose from!). The biscuits should represent the number 100.
The tag is in black and white so you can print the toppers onto coloured card and save your ink!
