A poster in GBHS math teacher Tina Hiss’s classroom at Great Bend High School reads, “This classroom is a mistake-making, laughter-sharing, independence-building, brain-stretching, mind-opening sort of place where everyone matters.” That attitude of truly caring about her students as well as her subject matter is no doubt the reason many GBHS grads recall Hiss as one of their favorite teachers. Last September, for example, a former student invited her to attend his wedding.
