Children have elaborate homework diaries and timetable books - why shouldn't teachers have them too? The Teacher Planner from Boomerang is a resilient A4 volume, packed with sheets to map out your working life.
There are spaces to write about meetings, duties, detentions, training and "things to do". There are also brisk pages of advice on how to reduce stress and "get the message across". Utilitarian assistance comes from lists of websites, spiritual relief from jokes by Peter Cook, Bill Cosby, Fran Lebowitz and others. Prices start at pound;4.95 from Boomeranged (contact details above).
