What is the best length for a pen? Will you ever be half the age of your teacher? Where can you walk to in one minute? These are only three of the 365 thought-provoking questions from next school year’s BEAM Mathematical Calendar 2004-2005, with its richly earned subtitle Maths is Everywhere. Each month comes with a beautiful and intriguing colour photograph, and every day has its own question, while weekends are allotted enjoyable investigations like making a star from folded paper. It’s a wonderful stimulus for talk and thought. The calendar costs pound;9.40 + pamp;p per copy (reductions for bulk orders) from BEAM Education, Maze Workshops, 72a Southgate Road, London N1 3JT.
