The Monograph Series is published by NCTM as a supplement to the Journal for Research in Mathematics Education (JRME). Each monograph has a single theme related to the learning or teaching of mathematics.

Funded by the National Science Foundation, the purpose of the LOGO Geometry Project was to develop a research-based grades K–6 geometry curriculum that addressed the deficits of the current curriculum. In addition to introducing the project and its rationale, this monograph details the research, results and implications of the study.
