<br/> The participants demonstrated a poor knowledge of, and performance in, mental multiplication at the level required of Year 5 students. Considering that the majority had experienced schooling in the last 20 years when curriculum planners had emphasised the importance of mental computation skills, there was a distinct lack of knowledge of appropriate strategies for this topic. The use of Hill, Ball and Schilling’s (2008) Mathematical Knowledge for Teaching (MKT) framework identified deficits in the participants’ knowledge of the topic and their preparedness to teach it. Whilst the intervention was well received, its short duration meant that significant gains could not be made in the participants’ own SCK. The data did show an increase in the range and flexibility of the strategies used to solve mental multiplication problems and an improvement in timed testing results. There was an attitudinal shift of the participants away from a traditional algorithmic approach to the topic towards more flexible, number sensible approaches. <br/> The research is significant as it adds to the literature concerning mental multiplication strategies and possible teaching programs in the later primary years. Whilst there is considerable research concerning mental computation, it has focussed largely on the early years of primary and, in particular, addition and subtraction. Studies of mental multiplication with pre-service and practising teachers are less common as are specific recommendations for appropriate strategies to include in teaching programs (Hartnett, 2007). Both the Australian and NESA outcomes and support documents are vague in this area with few examples of actual strategy use for mental multiplication. It is hoped that this study promotes further discussion of this topic leading to improved curriculum guidelines and flexible teaching approaches.
