Introduces an algebra lesson plan on two people saving money over the course of a week and the problems they encounter for early elementary school students. (YDS)

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…

Describes an activity on data management and statistics in which students were asked to think of a topic and collect information on it to analyze and represent in graphs. (ASK)

Discusses the importance of practitioners planning to exploit the motivational potential of the outdoor environment and supporting children's spontaneous learning across all aspects of mathematics. Presents outdoor activities, each of which involves several learning goals across all areas of mathematics. (KHR)

Illustrates how an activity called Incredible Equations was used to develop 2nd grade students' number sense and number concepts. Includes student-created equations and an analysis of the mathematics they learned. (Author)
