When a Ms. O from the past shows up at the office, Otto and Oscar must send her back to the day she came from or risk causing a time catastrophe. But how can they figure out what day she is from? Using the clues available and a calendar is a good place to start! The Odd Squad show aims at problem solving and thinking and includes building procedural fluency as well as building conceptual understanding. The show uses creativity and imagination to foster inquiry and math-talk.
