Reports on the development of a course in modern mathematics for elementary school teachers. The subject matter for the course is concentrated on whole numbers, integers, and rational numbers. Ideas of logic and set theory are brought into the discussion incidently as needed for developing the number systems. Part 1 of the course is a brief essay on "What is a Teacher." Part 2 consists of four chapters on Number Systems. Each chapter is divided into sections, and each section is identified as belonging to one of three "tracks" which are interwoven throughout Number Systems. Track A presents basic mathematical ideas. Track B consists principally of ideas for work by means of which mastery of the conceptual material of Track A is gained. Finally, Track C presents some ideas to indicate how the conceptual material of Track A might be used by a teacher in the elementary school classroom. Part 3 is a sequence of notes on 16 lectures concerning an experiment in elementary school mathematics instruction. [Not available in hardcopy due to marginal legibility of original document.] (RP)
