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.
Impact and interest:
Citation countsare sourced monthly fromand 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.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
