g. Draw developments of Pyramids
h. Produce transition pieces - square-to-square, round-to-round, square-to-round,
and rectangular-to-round
i. Understand the theory of intersections and their importance

III. ABBREVIATED COURSE OUTLINE

A. Introduction (lab safety, orientation, equipment issue and inventory,
textbook issue, course content, grading procedures, etc.)

B. Orthographic and Isometric Drawing Production (single stroke Gothic
lettering, alphabet of lines, line quality, visualization of views/surfaces,
dimensioning techniques, equipment usage, drawing to scale(s), etc.)

C. Cam Drafting and Design (cam displacement diagrams, types of motion, cam terminology, cam profile development from displacement diagram, use of specific instruments, etc.)

D. Gear Drafting and Design (gear terminology, types of gears, gear tooth construction, use of gear tooth formulas, meshing gear teeth, etc.

E. Descriptive Geometry (definition of Descriptive Geometry, using an axis of rotation, true length and bearing of a line, true size and shape of a surface, projecting to and from true size and shape surfaces, solving verbal/mathematical problems, etc.) 5 Weeks

F. Developments and Intersections (view relationship, stretch-out line,
rectangular developments, radial line developments, auxiliary views,
pyramid development, transition pieces, model development construction, etc.) 4 Weeks

IV. GRADING PROCEDURES
Students' grades will be determined by the accumulation of points assigned for the various assignments. The standard point value per drawing will be 0 to 9 points. Points will be totalled and the following scale used to determine term (nine weeks) grades: 90-100% = A, 80-89% = B, 7079% = C, 60-69% = D, less than 60% = F. Semester grades will be determined using the standard 2/5, 2/5, 1/5 scale (2/5 for the first term, 2/5 for the second term, and 1/5 for the semester exam). Students are encouraged to turn in extra credit work to increase their point totals. Extra credit work, however, is work above and beyond that which is assigned as a portion of the course. All assigned work must be completed before any extra credit work will be approved by the instructor.

V. BEHAVIOR. DISCIPLINE. and ATTENDANCE POLICIES
Students are expected to conduct themselves in a responsible manner and in compliance with all District policies and regulations. Any and all violations of such policies and/or regulations will result in disciplinary action initiated by the instructor and administered by the school administration. Listings of these policies and regulations can be found in student handbooks and/or student folders. Particular emphasis will be placed upon the wilful destruction and/or deliberate misuse of school and personal property. Remember - this facility (laboratory) will most probably be the location of your interviews for future employment and/or schooling - it is critical that it be maintained in the best possible condition at all times. Attendance is taken only once during the class period. This usually occurs between one and two minutes after the sounding of the "beginning-of-class" bell. Students not present at the time roll is taken WILL BE MARKED ABSENT for the day, unless they have a signed pass from another teacher or from the administration office. In short, students are either present or absent at the time attendance is taken.

I have read, understand, and will comply with the above stated information.
