Patterns that support early algebraic thinking in the elementary school
Warren, Elizabeth & Cooper, Thomas J. (2008) Patterns that support early algebraic thinking in the elementary school. In Greenes, Carole E. & Rubenstein, Rheta (Eds.) Algebra and algebraic thinking in school mathematics. National Council of Teachers of Mathematics, Reston, VA, pp. 113-126.
Over a period of three years, the authors conducted an extensive longitudinal study in Australia aimed at ascertaining teachers' actions, activities, questions, and conversations that support the development of early algebraic thinking in the elementary (primary) school classroom. The study was conducted in five classrooms and consisted of teaching experiments focused on the development of an understanding of equivalence and equations, functional thinking, patterning, and generalised arithmetic. In this article, they report on one of those experiments involving repeating patterns and geometric growing patterns. As the authors began their work, they were aware that students spend a great deal of time in their early years in school investigating repeating patterns, but they have little experience with geometric growing patterns. There are three major reasons for exploring geometric growing patterns in the elementary school classroom: (1) they are visual representations of number patterns, (2) they can be used as an informal introduction to the concept of a variable, and (3) they can be used to generate equivalent expressions. The specific purpose of the study was to identify and characterise activities that help elementary school students distinguish repeating patterns from growing patterns, to establish relationships between data sets, to extend patterns, and to develop an awareness of the synergy between patterns and tables of values. The article is organised by mathematical idea and illustrated with activities and students' work. They begin by describing how they distinguished repeating patterns from growing patterns.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
