Lesson Plan Course Title: Engineering Design and Presentation Session Title: Sketching Performance Objective: Upon completion of this lesson, the students will be able to sketch ideas/problems/products so that others can recognize what they are trying to communicate to the satisfaction of the teacher. Specific Objectives: Students will be able to: create thumbnail sketches of their six (6) favorite toys from their childhood identify childhood toys sketched by other students sketch the steps as to how they would draw the 2D and/or 3D CAD problems Preparation TEKS Correlations: This lesson, as published, correlates to the following TEKS. Any changes/alterations to the activities may result in the elimination of any or all of the TEKS listed. Engineering Design and Presentation: 130.365(c)(1)(E) identify and use appropriate work habits. 130.365(c)(3)(B) complete work according to established criteria. 130.365(c)(5)(A)(B)(F) sketch single- and multi-view projections. prepare orthographic and pictorial views. construct true length of lines and true size of planes by the revolution method. Interdisciplinary Correlations: English Language Arts and Reading, English IV: 110.34(b)(1)(A)(E) determine the meaning of technical academic English words in multiple content areas (e.g., science, mathematics, social studies, the arts) derived from Latin, Greek, or other linguistic roots and affixes; use general and specialized dictionaries, thesauri, histories of language, books of quotations, and other related references (printed or electronic) as needed.

role in geometry; geometric figures provide powerful ways to represent mathematical situations and to express generalizations about space and spatial relationships. Students use geometric thinking to understand mathematical concepts and the relationships among them. 111.34(a)(3) - Geometric figures and their properties. Geometry consists of the study of geometric figures of zero, one, two, and three dimensions and the relationships among them. Students study properties and relationships having to do with size, shape, location, direction, and orientation of these figures. 111.34(a)(4) - The relationship between geometry, other mathematics, and other disciplines. Geometry can be used to model and represent many mathematical and realworld situations. Students perceive the connection between geometry and the real and mathematical worlds and use geometric ideas, relationships, and properties to solve problems. 111.34(a)(5) - Tools for geometric thinking. Techniques for working with spatial figures and their properties are essential in understanding underlying relationships. Students use a variety of representations (concrete, pictorial, numerical, symbolic, graphical, and verbal), tools, and technology (including, but not limited to, calculators with graphing capabilities, data collection devices, and computers) to solve meaningful problems by representing and transforming figures and analyzing relationships. 111.34(b)(2)(A)(B) use constructions to explore attributes of geometric figures and to make conjectures about geometric relationships; make conjectures about angles, lines, polygons, circles, and three-dimensional figures and determine the validity of the conjectures, choosing from a variety of approaches such as coordinate, transformational, or axiomatic. 111.34(b)(3)(A)(B) determine the validity of a conditional statement, its converse, inverse, and contrapositive; construct and justify statements about geometric figures and their properties; 111.34(b)(6)(A)(B)(C) describe and draw the intersection of a given plane with various three-dimensional geometric figures; use nets to represent and construct three-dimensional geometric figures; and use orthographic and isometric views of three-dimensional geometric figures to represent and construct three-dimensional geometric figures and solve problems. 111.34(b)(7)(A) use one- and two-dimensional coordinate systems to represent points, lines, rays, line segments, and figures; Teacher Preparation: You will need 2-3 copies of the six (6) grid paper for sketching on per student. It is recommended that you make your own sketches to show the students. Have pencil, eraser, and map pencils available for students who don t have any.

Introduction Introduction (LSI Quadrant I): NOTE: The class discussion is meant to be Socratic in nature and not true/false, or this is the only correct answer. Encourage your students to explain WHY they think the way they do! There is NO wrong answer if they can explain the WHY! SAY: Today you will be able to create your own thumbnail sketches. ASK: Can anyone explain to the class what a thumbnail sketch is? ANSWER: It s a sketch that s about the size of a thumb that shows what a product will look like when completed. SHOW: Go through the What is Sketching? PowerPoint presentation. ASK: Can anyone give me examples of uses of thumbnail sketching other than in engineering design? ANSWER: Many, these are just a few. Plan a painting; plan scene in a movie; plan comic strip; plan a poster layout; plan layout for a website. SHOW: The example and see if they can guess what they represent. SHOW: Them the 2D and 3D Computer Aided Drafting (CAD) examples. ASK: Is this the ONLY way these could be planned out and drawn? ANSWER: No, this is just how I would plan and do it. As long as you can get it drawn, it will be correct. SAY: You will now practice creating your own thumbnail sketches. For the first 1-2 days of this lesson, you will practice drawing thumbnail sketches of your six (6) favorite childhood toys. Coloring is optional. On the 3 rd day, you will practice sketching out steps to draw the CAD problem(s) given. Outline Outline (LSI Quadrant II): Copyright Texas Education Agency, 2012. All rights reserved. 3
Instructors can use the PowerPoint presentation, slides, handouts, and note pages in conjunction with the following outline. MI Outline Notes to Instructor Days 1-2 practice drawing thumbnail sketches of your six (6) favorite childhood toys. Coloring is optional. Day 3= practice sketching out steps to draw the CAD problem(s) given. This is a 3 day lesson. I. Can anyone explain to the class what a thumbnail sketch is? Today you will be able to create your own thumbnail sketches. II. Today you will be able to create your own thumbnail sketches. (Slides 1-9) Begin showing and discussing What is Sketching? Power Point presentation. III. Can anyone give me examples of uses of thumbnail sketching other than in engineering design? IV. Show the example and see if students can guess what they represent. (Slides 10-12) Many, these are just a few. Plan a painting; plan scene in a movie; plan comic strip; plan a poster layout; plan layout for a website.. (Slides 25-27) Have some slides printed out for the kids who need to refer to examples. Discuss if color helped or not. V. Show the 2D and 3D CAD examples. (Slides 28-32) Ask the students Is Copyright Texas Education Agency, 2012. All rights reserved. 4
this the ONLY way these could be planned out and drawn? Tell them this is just how you would plan and do it. As long as you can get it drawn yours is correct. VI. You will now practice creating your own thumbnail sketches. Go around and help kids who need it. Allow 2 days to sketch the 6 toys. Allow them to use color if they want to. It helps some students to better visualize the process. VII. 2D and/or 3D CAD problems A. Thumbnail sketch the steps on how you would draw the problems B. Draw the problems on computer i. The Sling ii. The Adjustable Stop (Slides 33-35) When students begin the technical drawings in CAD or Parametric Modeling software like Inventor or Solidworks, require that they thumbnail sketch out the steps on how they would do the drawing BEFORE they begin to draw it in the computer.

Application Guided Practice (LSI Quadrant III): The teacher provides feedback as students are sketching their 6 childhood toys; and should show every student s sketches and see if everyone can guess what they are. Independent Practice (LSI Quadrant III): Students will complete the 6 childhood toys sketches on the gridded paper provided; and will sketch the 2D and/or 3D CAD problems. Summary Review (LSI Quadrants I and IV): As the students show their sketches, the teacher will ask if everyone can guess what the toys are from each sketch that is shown. Can you guess what the toys are from your classmate s sketches? Evaluation Informal Assessment (LSI Quadrant III): Make sure each student has 6 sketches to show. Formal Assessment (LSI Quadrant III, IV 1. The six (6) favorite childhood toys sketches should be graded as daily work 2. When you begin the technical drawings in CAD or Parametric Modeling software like Inventor or Solidworks, require that they thumbnail sketch out the steps on how they would do the drawing BEFORE they begin to draw it in the computer. 3.
