The youngest students on the Bethel College (IN) campus seat themselves on a colorful rug that has the letters of the alphabet marking the border.  They readily follow teacher Ariana Grabill’s request for quiet as they prepare to compete in a mathematics game.  These aren’t college freshmen. They are squirmy, giggly, energetic kindergartners enrolled in Lab-K, the kindergarten classroom that is a partnership between the college and School City of Mishawaka.
