This book derives from a series of sessions in which a study group of elementary teachers and their principals discussed children's mathematical work in relation to alternative assessment. The purposes of this book to describe the next tier of work for teachers in alternative assessment and how that work can be applied to elementary mathematics:…

This document presents a resource for elementary teachers in the form of a collection of facts and measurements of animals and planets to be used in generating student interest for these different topics. It is suggested that the teacher make an overhead transparency of the measurements related to the current topic, then have students guess at…

This book contains a set of versatile enrichment exercises that cover a very broad range of mathematical topics and applications in geometry including Euclidean, post-Euclidean, and non-Euclidean geometry. Several criteria have been used in developing the activities and selecting the topics that are included. All of them bear heavily and equally…
