In a lesson I was observing, the teacher says to the class, “Take a look at the board and see if you can solve the puzzle to find out what aspect of maths we’ll be looking at today.”
Silence ensues… “Any ideas?” he asks them after a minute. One girl raises her hand and he gives her the nod to answer.
“Put up your hand if you’ve broke your arm and can’t ride your bike?” she offers. I must confess to uncontrollable giggles.
