This pamphlet recommends that elementary-school teachers be provided with inservice courses which deal with probability concepts. The recommendations are based on the experiences of 120 teachers who taught probability in elementary school as part of a project of the National Science Foundation. The authors observe that probability is important enough to warrant a place in the curriculum, and that the number concepts involved in probability are already present in the elementary curriculum. A suggested outline of topics for an inservice course on probability is provided, together with detailed descriptions of three illustrative activities. (SD)
