This is a great end of term activity for when you want a little more challenge than just a standard quiz. This activity is designed to take a full hour, including set up and feedback. It is suitable for all age groups (I have personally used this with Year 7 up to Sixth Form, and it has been positively received) The booklet contains 15 mind bending riddles and logic puzzles. Each puzzle is worth a number of points depending upon difficulty. Students work in teams to get as many points as possible. The accompanying PowerPoint contains all of the answers, alongside explanations.
