Maths Test

I'm not one for taking my camera into the classroom mainly because lets face it a male taking photos of children is not exactly a good look but today my Yr 4/5/6 class undertook a Maths test in number sequences and I thought I'd try some 'test moments in time' type of shots. And yes I have made sure no faces are visible!
I really like the hand up in this shot as it breaks the concentration of the other children around him.
What are your thoughts?
