Teacher Name:

Grade:
 Grade 9-10
Subject:
 Vocational Ed.

Topic:
 Drafting, Computer-Aided Design
Content:
 Performance, Base Plate Drawing Key Vocabulary: decimal, fraction,radii,diameter, tangent, angle, intersection
Goals:
 Students will use drafting tools appropriately with increasing skill and precision
Objectives:
 Students will use drafting tools to render lines, arcs and circles in AutoCAD to create a prototypical part (M5.01.03) Students will behave like engineering professionals
Materials:
 Computer and AutoCAD software, paper, printer, Drawing board, T-square, drafting tool box
Introduction:
 Classroom Norms - 1. Bags away, sitting in seats for morning announcements 2. Take attendance during announcements 3. After announcements, students retrieve boards and boxes Welcome: State standardized objective verbatim: Students will create lines, arcs and circles in AutoCAD to create a prototypical part (M5.01.03) Then translate it into the objective of the day: Copy a Base Plate drawing Read and explain: Big Idea, Enduring Understanding, Essential Question Administer Do Now: What does the term symmetrical imply about a drawing or object? Ans: Balanced, equal, proportional, regular, mirror image etc. Question: Can anyone use symmetrical in a sentence?
Development:
 Access previous knowledge - We've already worked with circles and tangents before on previous drawings. Today we add the angled measure to the mix. I have high confidence that you can complete the assignment Strategies for success- Question: Where is the best starting point for this drawing? Ans: The big circle Why? Ans: Because all other points are reference from it
Practice:
 Distribute the base plate paper - DO NOT BEGIN DRAWING! Using the white board, draw the starting point that the students named Question: What is our next step? ANS: varies, but invite student to draw his/her answer with a different color marker. Continue method until complete
Accommodations:
 Break - have students come up and get word find puzzle. Allow 10 minutes work Return to drawing. Try to pair advanced/quicker students with others that need help Offer quality control tips - Faster isn't always better
Checking For Understanding:
 Is the drawing matching the design template? Why or why not? Offer tips if students are truly stuck or frustrated
Closure:
 Self-Assessment - How satisfied are you with your work? What are your strengths? What can you improve? Now that you have located circle by angle and tangent you can use these same techniques on the computer and on your next assignment. By the way, did you notice the hidden math lessons?
Evaluation:
 Informal assessment consists of my group/student table observations and suggestions. How well this goal is met can be measured by student accuracy, neatness and overall image quality Formal assessment consists of collecting and evaluating the drawings for classroom activity points (20 max) Documents are added to student portfolios for reflective activities.
