It is a lesson structure in which there are three parts (or acts). It creates an opportunity for students to become interested in modeling an accurate estimation/solution without the unnecessary myopic focus on the "right" answer.

Here is another very detailed walk-through of the Three Act Task structure. (From the inventor of the Three Act Task himself!)
