Melissa Knipes teaches kindergarten at Killington Elementary. This year, for the 28th time, she's welcoming a new class of students, 5-year-olds. Teaching kindergarten means expecting the unexpected, but usually it's the kids, not a pandemic, that throws a wrench in Knipes's plans. Eighteen months since the beginning of state of emergency, she feels confident she can keep herself and her students safe, and she's adapted her teaching to the new normal.
