Have you made a simple but useful discovery which saves time, quietens the class on a wet afternoon - or helps the children learn? Please share it with your colleagues: each successful tipster wins either a free copy of Ted Wragg’s Guide to Education or Barnabas and Anabel Kindersley’s Children Just Like Me. Indicate your choice on your submitted tips when you send them to Maureen McTaggart at The TES, Admiral House, 66-68 East Smithfield, London E1 9XY. Fax: 0181 782 3200
