Constructing magic figures in a secondary school. (English)
J. Interdiscip. Math. 6, No. 3, 349-356 (2003).
Summary: The usefulness of problem solving in the teaching of elementary mathematics has long been established. In recent years, a considerable effort has been performed toward the method of {\it try and find out}. In this paper we present a combinatorial problem proposed in a third year class of the Secondary State School that illustrates the value of this method.
