Russo, James – Australian Primary Mathematics Classroom, 2017
Benchmarking is an important strategy for comparing the size of fractions. In addition, knowing whether a given fraction is greater or less than a particular benchmark (e.g., one-half) can support students with accurately locating the fraction on a number line. This article offers a game-based activity that engages students in discussions around…

Chesney, Marlene – Australian Primary Mathematics Classroom, 2013
Marlene Chesney describes a piece of research where the participants were asked to complete a calculation, 16 + 8, and then asked to describe how they solved it. The diversity of invented strategies will be of interest to teachers along with the recommendations that are made. So "how do 'you' solve 16 + 8?"

Betts, Paul; Crampton, Amanda – Australian Primary Mathematics Classroom, 2011
In this article, the authors describe a reform-based activity concerning multiplication, developed within the context of the children's story "The Wonderful Pigs of Jillian Jiggs" by Phoebe Gilman. They also provide vignettes of informal multiplicative thinking by Grade 2/3 children that occur during these activities. The informal multiplicative…

Berman, Jeanette – Australian Primary Mathematics Classroom, 2011
Place value underpins much of what people do in number. In this article, the author describes some simple tasks that may be used to assess students' understanding of place value. This set of tasks, the Six Tasks of Place Value (SToPV), takes five minutes to administer and can give direct insight into a student's understanding of the number system…

Watson, Jane; Skalicky, Jane; Fitzallen, Noleine; Wright, Suzie – Australian Primary Mathematics Classroom, 2009
Among the practical applications of statistics is the collection of data from manufacturing processes. Often collected in the form of a time series, data collected from a series of measurements show the variation in those measurements, such as mass of a product manufactured. Limits are set for quality control and if these are exceeded then a…

Perso, Thelma – Australian Primary Mathematics Classroom, 2009
In May 2008, the first National Assessment Program for Literacy and Numeracy (NAPLAN) test was administered across Australia to determine the standard of literacy and numeracy achievement of Australia's students in Years 3, 5, 7 and 9. Some students did very well on the tests and some did not. This type of test can tell a great deal about…

Muir, Tracey – Australian Primary Mathematics Classroom, 2007
When asked to calculate the area of a particular shape, one student responded by asking, "Is that the outside or the inside?" while another student replied, "I think it's the one where you put a little 2 next to it." Both of these responses indicate a lack of conceptual understanding of area and reinforce the research findings…
