Question

1. Why are the children putting up their hands?​

Answer 1

Answer:

The teacher needs to be able to choose a single student to let answer or make a comment, instead of 25 kids shouting at once. It makes less difference as kids get older, but it definitely still makes one.

Hand raising has the benefit of being able to be seen from further back and completely silent.

Have a nice day. :)
