An experimental program using the calculator in third, fourth, and fifth grades is described. Three example lessons are included, on (1) subtraction with regrouping, (2) estimation, and (3) number theory: Quadratics. (MK)

In a series of projects centered in different areas of Africa, mathematicians from England and the United States joined African educators in developing and testing a mathematics curriculum designed to teach the basic concepts which are important and useful in all countries. (SD)

The role of mathematics education in the elementary school classroom over the next few years is reviewed. The need for extensive reform is emphasized, especially the inclusion of noncomputational number concepts. (MP)

What students need to know in a world where most computations are done by machine is discussed. Needed changes in the mathematics curriculum are then detailed in relation to mental arithmetic, numeration, decimals and fractions, paper-and-pencil computation, order of operations, problem solving, and instruction on calculator use.
