This is an Edexcel C3 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.
When I do this lesson I set a timer to sound every five minutes - every time the buzzer sounds I write an answer on the board.
This revision activity allows students to practise working under timed conditions and keeps them on task and engaged throughout the revision lesson.
These questions are fairly challenging so suitable for students working at a grade A. The questions are taken from IYGB papers from the brilliant website madasmaths.com. Answers are provided.
