Summary
Table of Contents

Dan Meyer has created many mathematics lessons centered around storytelling, along with a methodology for using these with students. Before you do any of his lessons, please see the explanation at his blog: https://blog.mrmeyer.com/2011/the-three-acts-of-a-mathematical-story/ To see all the lessons in a Google Docs spreadsheet, go to https://docs.google.com/spreadsheets/d/1jXSt_CoDzyDFeJimZxnhgwOVsWkTQEsfqouLWNN C6Z4/edit#gid=0 The lessons are all CC BY, and you may edit these to fit your own students’ needs. The links from #GoOpenVA go to his own website because the structure of the lessons (including pertinent videos) is integral to the delivery of the lessons. Some lessons are stored as downloadable zip files, and these are noted as part of the link.
