Here is a MATHS music video I made with my friends last year. Before you start watching think of a number then follow the instructions given throughout the video (watch carefully!). Your final answer should always equal 5. Can you get your students to work out why this always works? Can they use algebra to help them?
Here is the Kiesza video that we got the inspiration from: https://www.youtube.com/results?search_query=kiesza+hideaway
