Geometry Module 1

Geometry Module 1: Congruence, Proof, and Constructions

Module 1 embodies critical changes in Geometry as outlined by the Common Core. The heart of the module is the study of transformations and the role transformations play in defining congruence. The topic of transformations is introduced in a primarily experiential manner in Grade 8 and is formalized in Grade 10 with the use of precise language. The need for clear use of language is emphasized through vocabulary, the process of writing steps to perform constructions, and ultimately as part of the proof-writing process. 

The student materials consist of the student pages for each lesson in Module 1.

The copy ready materials are a collection of the module assessments, lesson exit tickets and fluency exercises from the teacher materials.
