Comprehension Instructional Sequence Model Lesson Plans: Subtractive Machining

Unit Description:

FLATE, the Florida Advanced Technological Education Center for Manufacturing, has developed a curriculum to prepare students for careers in manufacturing. These Comprehension Instructional Sequence Model (CIS) Lesson Plans are intended to “build learners’ background knowledge in STEM areas, expand their vocabularies, and to promote reading and writing success.” Each model lesson includes materials based around reading, research, industry tours, and reflection through discussion and essay writing.

The lesson is part of a collection of Comprehension Instructional Sequence Model (CIS) Lesson Plans.

Lesson Description:

This model lesson from FLATE focuses on subtractive manufacturing. In this introduction to the topic, students will: 1) Discover the process of subtractive machining, 2) Compare and contrast the subtractive and additive machining process, and 3) Analyze the benefits of subtractive manufacturing in today’s market. 

The completion of the lesson in full takes four 50-minute class periods. Resources available as part of this lesson include a Teacher Lesson Plan & Grading Rubric, a Teacher Lesson Guide Presentation, a Lesson Article, a Student Worksheet, and a Company Profile Worksheet.

For orientation purposes, viewers should begin with the ‘CIS Teacher Lesson MFG Day’ PDF document, which is included as a separate attachment. This document offers a description of the lesson as well as an overview of topics covered and the intended audience.

Lesson Contents:

The Lesson Plan document includes lesson objectives and expectations, relevant Common Core standards, required materials and supplies, a detailed sequence for both teacher presentation and student completion of the lesson, and a grading rubric for the essay that serves as evidence of student achievement.

The PowerPoint presentation covers an introduction to subtractive manufacturing and how it differs from additive methods of manufacturing, basic vocabulary, directions for student activities and assignments, and class discussion questions.

The 2011 article, titled “Will 3D Printing Revolutionize Manufacturing?" covers the potential of this additive manufacturing method, while the 2012 article, titled "Will Hybrid Additive Subtractive Fabrication Devices Prove to be the Key to Unlocking an Even More Successful Manufacturing Future?" compares and contrasts additive and subtractive methods and talks about the potential for using the two methods in concert.

The five page Student Worksheet, designed to be used throughout the four day lesson, includes space for students to think critically both before and after reading the article, a page for directed note-taking, and space to compose their reflective essay.

The Company Profile worksheet guides students in finding information online to answer questions about a manufacturing company.
