One of my favourite (and pupils’) revision activities that I use across KS3/KS4.
Shout-out to @teachgeogblog for the original idea.

Revision o ClockRevision o Clock 3Revision o Clock 2

Simply put, student’s revise 12 different topics in 3-4 minute time periods.
You can choose the topics or ask pupils to suggest ones they would like to revise.
They then have to fill each section with information, key words or pictures to represent what they can remember. Pupil’s like the challenge of picture section or key words, which is particularly useful at GCSE.
