Abstract
This paper reports on a section of the Early Algebraic Thinking Project (EATP) which focused on Australian Years 3-4 (age 7-9) students' abilities to generalise mathematical structure in relation to equivalence of expressions (with and without unknowns). It focuses on learning activities involving a sequence of representations to show that change resulting from addition-subtraction requires the performance of the opposite change (subtraction-addition respectively) by the same amount in order to return to the original state (e.g., x=x+p-p or x-q+q in algebraic symbols). It shows that children of this age can generalise this mathematical structure and that effective teaching for generalisation uses creative representation-worksheet partnerships.
Citations:
Citation countsare sourced monthly from Scopus and Web of Science 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 the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
