Reviews Lesson 0.3. Reviews Lesson 0.3, the plane crash simulation and the five-step decision model. Round 1 puts the ten items into the expert ranking, and every tap, right or wrong, shows the expert's reason from the handout key, because the reasons are the lesson. Round 2 is the five steps in order, then each step matched to its moment in the simulation, then the rule of threes. Use it the day after the simulation as a do now, and again before the Unit 2 Test (item 6 assesses the five steps) or before any project's five-steps planning box. Say before playing what the lesson says: a team that ranked two neighboring items the other way around with a real reason was not wrong; the game scores the key because a game needs one answer.
