Abstract
A teaching experiment was conducted with a small group of prep children considered ‘at
risk’ mathematically, to explore the effect of explicit instruction on the development of
tens facts through visualisation of the ten frame. After the two-week instructional period,
children could mentally recall all addition and subtraction tens facts without counting, and
this performance was considerably higher than the class average. In this paper, the sequence
of instruction is documented, highlighting the influence of instruction upon tens fact
development.
