THE ONTARIO CURRICULUM, GRADES 11 AND 12 | Technological Education
B3.2 create a materials list itemizing all materials and components for a woodworking project;
B3.3 plan and prepare for installation of various components used in woodworking projects (e.g., make a work schedule and list of tools required, check stock on hand, order materials);
B3.4 plan an efficient sequence for fabricating components for a project (e.g., use appropriate tools and techniques, do operations such as cutting and drilling in batches to reduce set-up time);
B3.5 lay out projects using a variety of measure- ment tools and equipment (e.g., laser level, tape measure, ruler, scale, protractor);
B3.6 describe and, where appropriate, make mod- ifications to woodworking projects to improve the quality and value of the project (e.g., choose different materials, hardware, finishes, or methods of construction and assembly).
By the end of this course, students will:
B4.1 calculate dimensions for woodworking proj- ects in appropriate metric and/or imperial units;
B4.2 convert between fractions and decimals and between imperial and metric units, using appropriate charts, tables, software, and/or online conversion tools, to determine dimen- sions and quantities for woodworking projects (e.g., convert lengths from inches to centimetres, areas from square metres to square feet, and vol- umes from gallons to litres);
B4.3 apply mathematical concepts and formulas (e.g., Pythagorean theorem, volume and area formulas) when preparing components of a woodworking project;
B4.4 determine lengths, diameters, and quantities of fastening devices needed to assemble various woodworking projects (e.g., lengths and gauges of screws, nails, and staples; diameters of dowels);
B4.5 prepare detailed, accurate estimates of quan- tities and costs of materials for woodworking projects (e.g., lumber, hardware, finishes), and of labour costs for these projects.
