Attend to precision Cross Cutting Concepts are bolded Core Idea Core Idea Question ETS1: Engineering Design EST1: What is a design for? Why would you want to design Mathematics – Geometry – Congruence – something before you build it? Experiment with transformations in the plane --A design is created to have a plan for creation of an object or Mathematics – Geometry – Congruence – process or system. We design before building for multiple reasons – Understand congruence in terms of rigid to optimize our solution, to test our solution using computer motion simulation before actual products (saves money), and for ease – it is Mathematics – Geometry – Geometric much easier to run multiple, even simultaneous, tests in a computer Measurement and Dimension – Visualize program than using life size materials. We want to test accuracy as relationships between two-dimensional and much as possible before executing the design. three-dimensional objects Math: What connections can be made between two-dimensional Mathematics – Geometry – Modeling with drawings and three-dimensional drawings? Geometry – Apply geometric concepts in --3D objects can be represented with 2D drawings called Nets. modeling situations Students will be able to explore symmetry of objects and two- and three-dimensions. Visualization skills will be developed as students learn to visualize and draw connections between the twodimensional net of an object and its actual three-dimensional shape. Math: Why would you need to visualize the relationship between two- and three-dimensional objects? --“The development or improvement of 3-D spatial visualization skills is often cited as one of the major goals of engineering design graphics education, (http://www.edgj.org/index.php/EDGJ/article/viewFile/126/122).” “Engineers are required to have a high level of visualization skills necessary in the design process and in the solution of engineering problems. However, many of the freshmen engineering students have problems in processing and understanding visual information or in developing mental images (http://core.ecu.edu/ITEC/chinr/59thmidyearproceedings/76.pdf).” Component Ideas Component Idea Questions ETS1.B: Developing Possible Solutions ETS1.B: Why might it be important to come up with more than one possible solution? --In mathematics, as in other subjects, there are always multiple ways to approach a problem. This is part of the beauty of math that often gets lost. Students need to see that there are, almost always, more than one answer to a problem and the fun and excitement and creativity of problem solving is finding your own solution! Grade Band Endpoints (Learning Intentions) ETS1.B: Students will use computers in representing a design in 3-D through CAD software Success Criteria Students will be able to visualize three dimensional objects from nets and orthographic drawings. Students will create a two-dimensional drawing of an object. Students will create a three-dimensional image in a CAD program of that object. Students will apply knowledge to transition from area to volume concepts. Formative Assessment Summative Assessment Two-dimensional drawing and threedimensional image created in CAD and Chapter 10 test journal describing understanding and Final Unit Project learning process. Integration Mathematics: Transitions between two-dimensional and three-dimensional thinking and visualization. Visualizing Volume from Area ELA: Students will journal about their experiences and their ability to visualize in three dimensions before and after the module. Other: Accommodations for Differentiated Instruction *Note: individual needs will be assessed after reading individual’s IEPs and upon meeting and working with students in the classroom. Special Needs English Language Learners Gifted & Talented Students will be provided Students will be given translations Students will be given more challenging designs with additional time to for instructions on which to work such as a bridge or kart. complete 3-D image and 2Possibly have students work without the D drawing. isometric dot paper. If needed, students will be provided with explicit examples of both isometric and orthographic drawings. Lesson Details Lesson 1: 1. Brainstorm Journal: What is the difference between two- and threedimensions? 2. Visualize the three-dimensional object created by a two-dimensional net. Students will be provided with a 2-D net and will be required to sketch the 3-D image of the object. Students who struggle will be given the option of first cutting out the net and then putting it together to see it in three Materials Needed and Additional Notes *8-12 blocks per student *Investigation sheet with steps *isometric dot paper *computers with Autodesk inventor installed on them or TapTapBlocks.com. In Lesson 1, as students are introduced to two-dimensional nets, they are engaged in discovering what the two-dimensional nets will create. They will be able to notice patterns in nets and work with their hands by cutting them out and gluing them together to make connections between their existing ideas of three-dimensional objects and the new idea that these can be represented with two- dimensions. 3. Students will be introduced to isometric and orthographic definitions and types of drawings. Students will define each and sketch examples of each type of drawing. Lesson 2: 1. Warm Up: Students will be given a sheet with a mix of orthographic and isographic drawings and be asked to match one to the other. 2. Students will explore two- and threedimensions. They will each be given 8-12 wooden blocks to build a threedimensional figure. Once they have decided on their figure, they will draw three orthographic views of their figure and an isometric drawing of their figure. Lesson 3: 1. Journal/Essay (to be turned informative assessment): What have you learned about two- and threedimensional drawing? How do you feel about your ability to draw in both dimensions? How do you determine each view from the other one? How has your ability to draw and visualize three dimensional objects changed? Explain, in detail, how to draw orthographically and isometrically. Explain how a net represents its three-dimensional object. 2. Students will be introduced to Autodesk Inventor. They will be given the rest of the day to learn and play with the program. 3. Homework: To choose an object from home (or imagination) of which they will sketch both orthographic and isometric drawings. This will be the image that they will create in Autodesk. Lesson 4: 1. Warm-Up: 2. Students will begin creating their 2-D sketch of their chosen (previous lesson’s homework) object. 3. Once the 2-D sketch is completed in Autodesk, students will work on extruding it to make it threedimensional. dimensional drawings. In Lesson 2, students will begin exploring with three-dimensional objects. They will use wooden blocks to build three-dimensional objects and figures. They will work with each other to build new and creative shapes. Their challenge will then be to translate their three-dimensional design into a two-dimensional drawing. In Lesson 3, students will journal about their experiences in the unit thus far. They will explain what they have learned and the connections they have made about two- and three-dimensional objects and drawings. They will make connections between their prior knowledge and new knowledge by answering the listed questions for Lesson 3 Journal. They will answer the question: What connections can be made between two-dimensional drawings and three-dimensional drawings? This journal will be part of their formative assessment for the unit. In Lesson 3, students will also begin to elaborate the skills they have been developing. They will be introduced to Autodesk Inventor. Students will practice drawing in two dimensions in the program and learn how to extrude their design to see it in three dimensions. They will apply the skills developed from turning nets into threedimensional objects to the designs they will now create in this program. They will begin to see why you would need to visualize the relationship between two- and three-dimensional object. In Lesson 4, will continue elaborating their two- and threedimensional design and visualization skills by working on the design of their choice. Using their chosen object, they will design it in twodimensions first in Autodesk Inventor, then they will work to extrude it correctly to look like the actual object they have chosen. In Lesson 5, students will be evaluated on their design in twodimensions and the final design in three dimensions. They will be evaluated on their reflection essay/journal about their experience, their new skills, and how their skills have changed and evolved through this unit. They will answer the questions: What is a design for? Why would you want to design something before you build it? There will also be questions on the final Chapter 10 assessment on this unit. **Possible extensions – continue with the different dimensional thinking. Students could read Flatland and discuss/debate the fourth dimension. This could also be an independent project for Gifted & Talented students. 4. To complete their image, students will adjust the lighting and material aspects of the image. Lesson 5: 1. Students will complete finishing touches on their image and submit both the Autodesk file and their sketches of the object by the end of this class. 2. Students will write a reflective journal/essay about their experience and their now expertise in two- and three-dimensional visualization. Approximate Time Needed: 5 50-minute class periods or 3 90-minute class blocks 5 e’s Instructional Design ENGAGE Give students a 2-Dimensional Net of a cube. Question: Can you visualize the three-dimensional object created by this net? If yes, draw the three-dimensional object using isometric dot paper. If no, cut out the net and fold along the lines to make the three-dimensional object and then draw it on the isometric dot paper. EXPLORE Isometric means “having equal measure.” So in our warm-up, the edges of the cube were drawn isometrically and all have the same length. An Orthographic drawing shows the faces of the solid as though you are looking at them head on. (see ex pg. 555-Discovering Geometry) Students will enhance their visualization skills and do isometric and orthographic drawings. Ex A: Make an orthographic drawing of the solid (provided on handout) – draw top, front, and right side views. Ex B: Draw the isometric view of the object shown on handout as an orthographic drawing. The dashed lines mean that there is an invisible edge. Exploration: Isometric and Orthographic Drawings – students will build block models and draw their isometric and orthographic views. (Copies of activity needed for all groups and group members) Notes/reflection EXPLAIN Journal: What relationships do you see between isometric and orthographic drawings? How might you draw each kind of drawing if you are given the other kind? What fields might use this type of drawing? How is an isometric drawing different from a two-point perspective view (ask only if we had time to do exploration in ch 3 on perspective drawings)? What types of two dimensional shapes show up in your drawings? ELABORATE Students in groups will use the Autodesk Inventor program to make orthographic drawings of their own shape. They will then extrude their drawings (or rotate, whatever needed) to create their isometric shape. Students will submit their two dimensional sketch of their drawing and then email me or show me their file of their three dimensional isometric figure. Students will later use these concepts to make connections between area and volume. EVALUATE *Students will be evaluated on their final submitted two dimensional drawings and their final three dimensional designed file as well as their journals. *Students will be able to visualize three dimensional objects from nets and orthographic drawings. Additional project for advanced students: 3D Shapes for Engineering design a functional structure, such as a bridge or a moving cart, making its constituent parts into the simplest geometrical forms possible. Require that students create two-dimensional diagrams of the form from at least three different angles. This will help them to make the connection between twodimensional and three-dimensional shapes, as each diagram will show how the 3D form intersects a different two-dimensional plane.
