Muir, Tracey; Watson, Jane – Australian Primary Mathematics Classroom, 2017
This article provides examples of teachable moments that are based on mathematical teaching episodes that the authors have either taught or observed, followed by discussions on how teachers might respond to these moments. It is hoped that this article may act as a stimulus for collaborative professional conversations as to whether or not teachable…

Fitzallen, Noleine; Watson, Jane; Wright, Suzie – Australian Primary Mathematics Classroom, 2017
When working within a meaningful context quite young students are capable of working with sophisticated data. Year 3 students investigate thermal insulation and the transfer of heat in a STEM inquiry, developing skills in measuring temperature by conducting a statistical investigation, and using a stylised graph to interpret their data.

English, Lyn; Watson, Jane – Australian Primary Mathematics Classroom, 2016
Statistical literacy is a vital component of numeracy. Students need to learn to critically evaluate and interpret statistical information if they are to become informed citizens. This article examines a Year 5 unit of work that uses the data collection and analysis cycle within a sustainability context.

Watson, Jane – Australian Primary Mathematics Classroom, 2015
Using statistical literacy skills to determine appropriate scales to be used on graphs is an essential part of numeracy. Using several meaningful contexts, this article explains very clearly when it is appropriate and inappropriate to begin the scale of a graph at zero.

Watson, Jane; English, Lyn – Australian Primary Mathematics Classroom, 2013
Jane Watson and Lyn English use a chance activity exploring expectation and variation with coin tossing to highlight the importance of understanding the part-whole relationship embodied in percentage and its power to measure and compare for different wholes, in this case different sample sizes. The purpose of this article is to raise awareness of…

Brown, Natalie; Watson, Jane; Wright, Suzie; Skalicky, Jane – Australian Primary Mathematics Classroom, 2011
Measurement is one of the key areas of study in mathematics and features prominently in the "Australian Curriculum: Mathematics" (ACARA, 2010). In this set of investigations requiring students to estimate indirectly the height of a tree they are encouraged to use the "power of mathematical reasoning" and "apply their…

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…

Watson, Jane – Australian Primary Mathematics Classroom, 2007
The fortunes of chance and data have fluctuated in the mathematics curriculum in Australia since their emergence in the National Statement in the early 1990s. Their appearance in Australia followed closely on similar moves in the United States. In both countries the topics, taken together, were given a section status equal to other areas of the…

Tabart, Paul; Skalicky, Jane; Watson, Jane – Australian Primary Mathematics Classroom, 2005
The authors discuss proportional reasoning as a challenging yet central concept for students in the middle grades that lays a foundation for mathematics studied later in high school. Four types of proportional reasoning problems are discussed: (1) Part-part-whole (comparing a subset (part) of a whole with its complement (other part) or the whole…
