A4 colour word printable with 2 fans per sheet:
orange straight mouth
red sad face
To be used for pupils to show how secure they are in the work (self assess feedback) OR as teacher's behaviour feedback (as I use them most) - I put one on their table to show them how I think they're doing.. green=good, orange=warning, red=trouble! I don&'t get to red very often, orange works a treat!
Laminate them, holepunch and secure with a book ring (staples sell them).
