Can You Lift 100 Kilograms? The Lesson Research Cycle

Facilitation Tools | Grades 5-6

A video by the Lesson Study Group at Mills College.


This video follows the Lesson Study process of a group of grade 5 and 6 teachers at a public elementary school in Tokyo. The teachers plan a unit and research lesson on levers, teach the lesson to a fifth-grade class as the school’s faculty observes and collects data, and conduct a colloquium to discuss the lesson. Their work is part of a schoolwide Lesson Study effort focused on the school’s research theme.
