Term 3 week 3, according to a child councilor I have worked with in the past, is a 'tricky week' for some students. This can be the time that negative behaviours start to rear their heads, even in students who have not had issues earlier in the year. This is the time of the 'equinox' - the change of seasons and this particular  councilor believe this has a negative affect on some students. Whether you believe this or not, I have found that this certainly a tricky time of year. It would be interesting to see if anyone has data around this 'phenomena'. We need to consider what we do to keep children on track and getting through to the end of the term in an appropriate manner. One strategy I have found useful is the child who is heading off track behaviorally goes to a buddy class as the teacher's helper. This is not seen as a punishment but more as 'distraction therapy'. Most children thrive on being given responsibility. Let's see if this will work this week.
