Team Umizoomi takes the math class at Strange Hill High when the robotic math teacher, Mr. Nimrod, is malfunctioning.
Realising the problem
Mr. Abercrombie: Miss Grimshaw, Mr. Nimrod isn't working properly, and we need to find a substitute teacher.
Miss. Grimshaw: Well, I know a small team called Team Umizoomi that lives nearby. They're known for their "mighty math powers". They even have a robot on their team! They'd be the perfect substitute for Mr. Nimrod.
Mr. Abercrombie: What's their number?
Miss. Grimshaw: Their number is 555-9175.
(Mr. Abercrombie calls the number)
Team Umizoomi gets the call
Bot: I'm getting a call on the Umi Alarm! That means someone's in trouble.
(Miss Grimshaw and Mr. Abercrombie show up on Bot's belly screen)
Miss. Grimshaw: Team Umizoomi, we need your help. Our robotic math teacher isn't working properly. Can you substitute for him, please?
Milli: We've got mighty math powers! We can definitely teach a high school math class!
Miss. Grimshaw: OK, I hope to see you soon.
