This advice is taken from our website’s recent blog post about revision () so that you can print it up and distribute to students. It is geared towards science (specifically chemistry), however it is relevant to all subjects!

A new, unique, take on the classic "Red, Amber, Green" traffic light-style flash cards. When students are working they display one of the three cards to show their teacher how they feel about the work they are doing. Green represents students who understand the task at hand, and maybe will finish earlier than everyone else, or who may need something more challenging. Amber represents students who are attempting the work, but it is challenging for them. Purple represents students who don't understand the work at all.
