Give your class or students 5 chances to behave before the "flask" fills up and your patience bubbles over!

Whether you want to keep the noise volume to a reasonable level, encourage better behaviour in class, remind your students of the classroom rules... or whatever, this countdown sign is a great and novel way to warn students, before they experience the consequences!

Simply download and print out the pdf. Cut-out the pieces and add magnet stickers, "velcro" tabs or sticky tack to the back of the pieces and flask. Then attach one piece to the flask, each time your patience is pushed.
