Estimating Angle Competition Starter / Plenary

A mini-whiteboard activity that is a favourite with my students. Students have to estimate the size of the angle to the nearest 5 degrees. All the answers are multiples of 5. They have 30 seconds to estimate the size of the angle with the classic countdown tune playing in the background. Enjoy!
