Early childhood development researchers have discovered that a simple, five-minute self-regulation game not only can predict end-of-year achievement in math, literacy and vocabulary, but also was associated with the equivalent of several months of additional learning in kindergarten. Claire Ponitz from the University of Virginia and Megan McClelland of Oregon State University assessed the effectiveness of a game called the Head-Toes-Knees-Shoulders (HTKS) task, which is a new version of the Head-to-Toes task developed by researchers at the University of Michigan.
