[Dawn Andersen-Lux]

Playing "Loud or quiet" is a good way to grab the attention of younger children, teach behaviour-related vocabulary and, at the same time get them to let off steam.
Get the children to shout "loud", as loud as they can. Ask them to shout it louder, then louder. Then get them to whisper "quiet" a few times, as quietly as they can.
Each time tell them to say it more quietly, until it is barely audible, then get them to shout "loud" again.
You can usually repeat this excercise quite a few times without them getting bored. It helps pad out a lesson when you run out of ideas, the little ones have picked up on that and getting restless.
You can also teach quite a lot of different words around the "quiet" & "loud" theme with this game.
