The video comes after sixth formers were given the multiple choice question in a further maths exam last September.
Featuring two 50 cents (neither the real Fiddy I'm afraid), the puzzle asks students to find the angle formed when these 12 sides objects are placed side by side.
The possible answers were:
a) 12 b) 30 c) 36 d) 60 e) 72
Any idea? Us neither. But we should be able to do it. According to one teacher at the school in Victoria the question is easy!
Gimme a break! My Year 5s could have worked it out.
Watch the video to see the possible solutions or,
MindYourDecisions suggests using a "Ghost coin" to find angle. By imagining a third 50 cent piece you can turn the angle into a triangle.
What seems to have confused the students was basically overthinking it.
