A Lesson Kit is one exhibit’s Lesson (A###), which you run from the front of the room, plus its Interactive (N###), which students work through on their own devices. Both cover the same idea with different situations and numbers, so students carry over the reasoning, not the answers.
The Survivorship Bias kit is yours to use: run the lesson, Where Should the Armor Go?, with your class, then let every student try the matching interactive on their own.
Every kit costs less than buying its lesson and interactive separately. One price covers all of your own classes.
