Pupil Voice is an important part of my Talk Audits; here are some recent responses when I asked Key Stage 2 children their opinions about Hands Up:
My hand is always tired!
Hands Up isn't fair because some people sit back and let others do the work.
I prefer random selection because it's fairer.
Sometimes more thinking time is needed.
Your hand gets tired when someone else is speaking.
Lolly Sticks are better than Hands Up because anyone could get chosen; we all have to have an answer. It gets everyone in the class thinking, not just one person.
