Hi there, I'm keen to implement a new behaviour management system and thinking of gem/marble in the jar style. I've seen this in a couple of schools but can't quite remember what actual rewards the children got from it! Does anyone do anything similar to this? When the jar is full would you allow 5 minutes extra playtime/extra golden time? I'm not sure! At the moment our golden time is quite short so it would be possible to add on 10 minutes extra golden time for a full jar of gems...is this how it is supposed to work?
