Written for the Commission on Crystallographic Teaching of the International Union of Crystallography
The IUCr is pleased to make available once again Betty Wood's classic text as an addition to the Teaching Pamphlets series. The original edition was addressed 'To the Teachers of Young Children Everywhere', and in an effort to extend the reach of this text as widely as possible, a number of volunteers have generously given of their time and effort to produce translations in a number of other languages.
