The key to a successful SOLE is framing a "BIG" question which sparks the curiosity of all learners...
'When is something worth celebrating?'
'Do all people and countries share the same Religion?'
'What would life be like with only whole numbers?'
‘Can you find the volume of a rectangular swimming pool without its dimensions?’
'Why are satellite dishes parabolic?'
'What was MTV’s contribution to the evolution of rock video?'
