Abstract
This study explores two Year 2 teachers’ perceptions of the affordances of a novel
mathematical manipulative, the Keyboard, based on their observations of its use in the
classroom. Analysis of the semi-structured interviews indicated that the Keyboard’s
linear structure, design features, and hands-on nature promoted flexible number
strategies, relational reasoning, and student engagement. It was viewed as a valuable
complement to other tools, with potential applications extending beyond its initial
design. These findings contribute to research on the role of specific manipulatives in
primary mathematics education and highlight implications for instructional practice.
