Hanten Lessons

Five minutes. One discovery.

Ready-to-use whole-class lessons that ask students to commit to an idea before they see what happens—and then apply what they discovered somewhere new.

What is a Hanten Lesson?

A Hanten Lesson runs for five minutes from the front of the room. Students commit to a prediction before they see the answer, then work out why it happened and use the idea somewhere new. No prep, and built for discussion.

How five minutes runs

  1. AskA question on screen that most of the room thinks they can answer.
  2. PredictEveryone commits to an answer before anything is shown.
  3. RevealThe real answer appears, often not what the room expected.
  4. UnderstandWhy it happens, with a slider you can move live to test the idea.
  5. TransferStudents apply the idea to a new situation.

Discovery before explanation.

Students notice, predict, test, and transfer the idea before the lesson is named for them. The structure stays familiar; the discovery changes each time.
