Mathella and the Ups and Downs of Her Rational Day: A story about rational numbers in Bloomington, MN

In this adventure, Ella and her dog, Integer, set out with a basket of goodies for Grandma. However, Integer is soon running back and forth which causes Ella to recalculate the distance. To add to her day, a wolf confronts her. Thank goodness for her red cape (or math) which helps save her from the wolf.
