Geometric Dimensioning & Tolerancing Scaffolded Phenomena-Based Lesson: The Flange That Passed Size and Failed Position (North Ridge Pump Works) Presentation | Pre-Engineering Drafting and Design | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Scaffolded Phenomena-Based Lesson in the Pre-Engineering Drafting and Design (grades 9–12) chapter Geometric Dimensioning & Tolerancing, built around the phenomenon The Flange That Passed Size and Failed Position (North Ridge Pump Works). This scaffolded version adds sentence frames and extra supports for students who need them. It is sold separately from the other two parts of the set.
