The Early-Math Discourse Audit: recorded-lesson feedback for early-years teachers

A professional-development service where a teacher of 4-8 year-olds records two or three ordinary math lessons on a phone and gets back a one-page profile of their actual teacher-child exchanges — who does the reasoning, what question types dominate, how wrong answers are treated — plus one concrete reframe to practice. The wedge is making the interchange, the thing research actually analyzes, visible to the teacher.
