One, Two, or Three? is an investigation into how we perceive the boundaries between different sets, or groups of similar objects. We often take for granted our natural ability to divide our world into sets. Which number comes to mind when you see each of the images above? How many sets do you see in each image? There are no single right answers – we can prioritize different visual cues to divide each image in different ways.
The Play Math exhibit showcased this project both as an interactive experiment that collected participants’ responses to the images, and as a set of play cards.
