These materials were written with the aim of reflecting the thinking of the Cambridge Conference on School Mathematics (CCSM) regarding the goals and objectives for school mathematics. They represent a practical response to a proposal by CCSM that some elements of probability be introduced in the elementary grades. These materials provide children with a variety of activities involving probability and statistics in a laboratory setting. Opportunities are provided for children to gain experiences in various types of situations - performing experiments, recording data, graphing experimental data, determining mathematical models for chance events, and computing. The experiences described in this report are intended to give students the opportunity to become familiar, by direct experiment, with important probability concepts before they are to be studied at a more sophisticated level.
