Como is a tangible device used in schools to teach children aged 6-10 to recognize healthy and unhealthy foods. It works by physically transforming when it scans different foods, exaggerating the effects of nutrition intake by changing its shape to appear thin, ill, or gaining weight. The goal is for children to learn about selecting healthy foods while also monitoring the class's average nutrient intake, as they take turns bringing Como home each week to identify foods on their own.
