Postulates three objectives for requiring students to do algebraic or geometric proofs and discusses the validity of these objectives. (RT)

Presents content and approaches for teaching geometry at the K-6 level. By use of the discovery technique, the author demonstrates how various topics can be taught beginning in three-dimensionalspace with the study of solid shapes. The sequence begins with the sorting of solid shapes, is followed by the ordering of solids by size and leads to the…

Six short articles concerned with mathematics education are included. (FL)

A new syllabus for teaching geometry in the fourth-grade of Soviet schools is described. The methodological principles underlying the teaching of geometry in grade four and the material taught are discussed. (FL)
