Mr. Donovan takes the stand to tell the judge what happened on Wednesday, April 19th. But his story doesn’t quite add up—there are 3 mistakes hidden inside! Two are math errors, and one is a science slip. Can your students catch them all?

Two videos are available:
Teacher’s Guide – Watch before class
A short prep video with instructions and tips for leading the activity.
Classroom video– Play in class
The main video for students helps them solve the math challenges in class.
Play the video until the judge tells Mr. Donovan he isn’t telling the truth (at 06:40). Pause and ask students to identify the 3 mistakes. Then, continue the video to check their answers and hear the explanations.
The Courtroom segment can be viewed by all ages, however the math level is for grades 2-6.
This episode covers telling time, addition, division, and a science twist: light travels faster than sound.

Ask students to write their own short story with a few “math mistakes” included. The errors can involve time, distance, age, weight, money, or any numbers they like. Then, let classmates swap stories and play detective.

Please take a moment to share your thoughts on the show and the segments you used in class.
