Abstract Often introduced as repeated addition, multiplication is usually associated with memorising and calculating—few people have images or metaphors for this concept. The multitouch application TouchTimes (TT) was designed to provide alternative models of multiplication that could be introduced alongside repeated addition, through tactile, visual and dynamic interactions. In this talk, I will describe some of the design intentions of TT as they relate to the existing literature. I will also show how students’ experiences with TT provide them with multiple senses of multiplication, as evidenced in the drawings made by a class of grade 3 students newly introduced both to multiplication and to TT.
