Teachers' Notes
Orthographic projection, in its simplest form, is a precise method of representing an object in three views; front view, side view and top view.
Isometric projection is a method of viewing, in perspective, an object, three-dimensionally.
Teaching orthographic and isometric projection to elementary students gives them a significant advantage in technological communication; that is, the ability to explain their technology ideas to other people.
Before going on, please consider the "Important Information" notes I have made for teachers before beginning a technology program in the classroom.
1. First, before you start, check and make sure you have access to a photocopier that will copy 279 mm x 432 mm, (11” X 17”), paper. Most schools have photocopiers that photocopy this size paper. Check to see that you have a supply of this size white paper in your stockroom. If you don’t, purchase two reams.
2. Talk to your principal or administrator who controls your school’s consumable budget. To carry out this project you will need approximately $10.00/student for tools, instruments and drawing supplies.
3. Investigate and determine if one of the major building supply stores stocks 3mm, (1/8”) Masonite. Masonite is the brand name of a synthetic material that has many uses. It is also referred to as “hardboard”.
4.Send an introductory letter home describing what you want to do. There is a strong possibility you may have a parent or grandparent who has building experience. They may have the time to help you with organizing a class set of thirty small drawing board; 30, (12” x 18”). Note: save all your small pieces of Masonite. They can be cut for a purpose and spray painted to make blackboards and templates.
5. You will need a role of 2cm wide masking tape for each group of four students in your class. These rolls of masking tape need to be organized for easy use in your room. Many of my students purchased their own roll of masking tape.
6. Each student will need a pencil, 30cm ruler, scissors, small box of pencil crayons, and a hand pencil sharpener.
7. Once you have organized all of the tools and materials, it is now time to make an orthographic and isometric drawing template.
