Odd Squad (stylized in all caps) is a live action children's educational comedy television series^[4][5] created by Tim McKeon andAdam Peltzman. The series premiered onTVOKids in Canada andPBS Kids in the United States on November 26, 2014. Similar toCyberchase andPeg + Cat, the series involves child characters using mathematical concepts (addition, multiplication, using data in graphs, etc.) to advance each episode's plot. The series features child actors (whose characters are the employees of the "Odd Squad") who use indirect reasoning and basic math to solve and investigate strange happenings in their town.

The series follows the exploits of Odd Squad, an organization run entirely by children, that solves peculiar problems using math skills. In the first two seasons, it typically features two employees of the organization's investigation division that work in precinct 13579 of the organization—Agents Olive (Dalila Bela) and Otto (Filip Geljo) in the first season and Olympia (Anna Cathcart) and Otis (Isaac Kragten) in the second season. Selected episodes feature other types of employees of the fictional organization, like security officers, so-called "tube operators" and scientists. The names of the employees nearly always start with the letter O. Agents are typically assigned cases by their boss, Ms. O (Millie Davis), and travel via a system of interconnected tubes to get to their destinations. They deduce the solution to the problem or how to detain the perpetrator by using basic mathematical principles that are typically the focus of the episode. Often, they cannot solve the problem at the scene and must go back to their precinct's headquarters or to the "Mathroom", a sentient space that communicates through largepaper fortune tellers and can unfold them to display information to help the agents see connections and better solve their case. Along with math, agents also use "gadgets" designed by the scientists; in the first season, Agent Oscar (Sean Michael Kyer) heads the lab, gaining an assistant, Agent Oona (Olivia Presti), in early season two who eventually takes over the lab after Oscar is promoted.

The characters have to deal with a variety of recurring villains who often put a mathematical spin on their plots. The seal of the Odd Squad headquarters depicts ajackalope carrying a shield in front of it (bearing an image of the seal—an instance of theDroste effect) and bananas at each side of it. The third season, dubbedOdd Squad Mobile Unit, sees a setting change from precinct 13579 to a van; in this season, four agents are assigned by the Big O (Davis) to work in the van and travel the world solving cases where local precincts either can't reach or need extra help. The fourth season, dubbedOdd Squad UK, is set in an Odd Squad location in the United Kingdom.^[6]

• Agent Olive (Isabela Moner, pilot;Dalila Bela, season 1): Referred to as a longtime employee of the Odd Squad, Olive began season one of the series adapting to working with and training her new partner, Otto. Olive is usually calm, brisk and serious. She has a morbid fear of pies, which she acquired after saving her organization's building from a pie-related disaster caused by her former partner, Todd. In the season one finale, Olive departs the series along with her partner, Otto, to run a different Odd Squad precinct as Ms. O.
• Agent Otto (Jaden Michael, pilot;Filip Geljo, season 1): Olive's partner and, in the first episode, the newest employee of the organization. In contrast to his partner's more serious demeanor and personality, he is a more lenient, laid-back employee. Despite his lack of experience with his job, Otto frequently uncovers the facts needed to solve the case at hand, even doing so in the absence of his more experienced partner. In the season finale, Otto departs the series to run another Odd Squad precinct as Mr. O with Olive as his partner.
• Big O (Millie Davis, seasons 1-3): Known as "Ms. O" (the title of any female head of an Odd Squad division) in the first two seasons, she is a very strict boss. She tends to yell (a habit seen less frequently as the series progresses) and is often seen sipping a juice box. Despite appearing younger than most of the agents, Ms. O's tenure at the precinct and her actual age remain a mystery. In-show, it is revealed that her actual name is "Oprah." In the season two finale, Ms. O is promoted to the rank of Big O, the leader of the entire Odd Squad organization. She leaves the show after the Season 3 episode "Odd Off The Press" due to traveling to outer space, appointing Orpita, an agent-in-training, as the Little O to replace her.
• Agent Oscar (Sean Michael Kyer, seasons 1-2): Oscar was the precinct's headscientist, in charge of thelaboratory. Other employees go to him for technical solutions to their problems.

He appoints Agent Oona to take over for him.
• Agent Olympia (Anna Cathcart, season 2): Introduced in the first episode of season two, Olympia joins the series to fill in the opening left by the departure of Olive in the season one finale.

He has a fear ofducks, revealed in the season two finale to be related to the fact he was once part of a family of villainous ducks. Ms. O took pity on Otis and trained him herself to become an Odd Squad agent.

• Agent Omar (Jayce Alexander, season 3): Originally stationed in the Arctic with Opal, he is known to value friendship and connection with his fellow agents, often attempting to mediate or calm the waters among his team, although his tendency to do so can sometimes distract him from the mission at hand.

• Agent Orla (Alyssa Hidalgo, season 3): Orla joins the Odd Squad Mobile Unit after being isolated for 400 years at an ancient Odd Squad headquarters protecting the powerful 44-leaf clover. Because of her separation from society at large and her history standing guard, she is often unfamiliar with modern inventions and has a tendency to react to situations quickly and without forethought.
• Agent Osmeralda (Glee Dango, season 3): Appearing as Esmeralda Kim in early season 3, she often showed up desiring to help but stating she was too busy with various hobbies such as karate or music instrument practice. In "Odd Off the Press," having finally cleared up her schedule, she is brought in to fill the opening left by the departure of Opal. She brings her out-of-the-box thinking skills to the team.
