Multiplication is often taught as repeated addition, especially in the early years of school, which leads to challenges for students when they encounter situations in which they have to think multiplicatively. TouchTimes is a new multitouch App that builds on the insights of prior work (especially with TouchCounts) that has been designed to offer a gesture-based mode of mathematical manipulation and communication. It has been designed to offer a more Davydovian approach to multiplication that enables haptic, symbolic and visual forms of engagements. I will report on preliminary results, focusing primarily on the bi-handed gestural interactions that 8-9 year-old children use to express multiplicative events.
