This is an Edexcel C1 revision activity based on the idea shared by Mel in this post: http://justmaths.co.uk/2015/10/18/keeping-time/.
Each student is given 12 questions (on A4) and a clock face (on A3). Students write their workings and answers in each section of the clock. Every 5 minutes or so students should be moving on to the next question/section. If all goes to plan they complete all 12 questions in a one hour lesson.
This revision activity allows students to practise working under timed conditions and keeps them on task and engaged throughout the revision lesson.
I have made two versions, both with answers.
In the first version, the questions are taken from old practice papers and are fairly straightforward. Some of my students got through these questions in 30 - 40 minutes.
In the second version, the questions are much more challenging. These questions are taken from IYGB papers from the brilliant website madasmaths.com.
