Miss Mary is beloved by her students. She makes learning enjoyable and easy, and her brightly colored knitwear brings a smile to everyone's face. Walking to school on the last day before the Christmas break, Miss Mary envisions all the fun students will have at recess. They'll make snow angels, build snowmen, and play other winter games. But recess isn't fun. No one wants to play. The snow is cold and the children don't have any mittens. Not to worry, thinks Miss Mary. She will knit mittens for her students as a Holiday surprise. But the store has run out of yarn, with no more deliveries before Christmas. Oh dear, where can Miss Mary find the yarn to knit mittens for her students?
