Introducing Linear Measurement in the Primary Grades

Abstract

Linear measurement is a complex concept. In order to become proficient in linear measurement one must understand and perform numerous components. The following lessons introduce primary students to linear measurement using research proven methods to increase understanding. The lessons are created to capitalize on students’ misconceptions. The following paper is divided into three main sections. The first section is “Lesson Goals and Criteria.” In this section the general ideals and standards used to guide the formation of the lessons are outlined. This paper examines the problem selection, introduction of problem, exploratory activity, and discussion. The second section contains four lessons as well as four papers of “Explanation and Justification” to accompany each lesson. The four lessons concentrate on measuring techniques, importance of the standard unit, a footstrip similar to a yardstick, and the use of the phase “part of” to represent a fraction. The final section, “Lesson Components,” outlines the components considered in the creation of each lesson. All lessons give weight to learners and learning, learning environment, curriculum and instructional strategies, and assessment. The paper outlines and explains to educators lessons for introducing linear measurement to primary students.
