In this Cyberchase video, Bianca has a new job decorating fresh-baked donuts. Her supervisor asked her to decorate 12 trays of donuts, but Bianca thought he meant 12 donuts. When she discovers her mistake, she uses multiplication strategies and an understanding of repeated addition to discover the true scope of her job. In the accompanying classroom activity, students play a game against the teacher in which students get practice multiplying two-digit numbers.
