      Mark out and prepare materials: papers and boards

      Lesson details

      Learning outcome

      I can mark out materials accurately to manufacture my design.

      Key learning points

      1. When measuring paper and board rulers, set squares and protractors are used.
      2. When marking out paper and board orthographic projections can be used.
      3. Using the correct tools and equipment is important to ensure accuracy when marking out.

      Keywords

      • Marking out - the process of measuring and drawing on a material before manufacture

      • Accurate - correct and precise

      • Measuring - determining the size of an object using a tool

      Common misconception

      Any marking tool will work on any material.

      Using the wrong tool (e.g a pencil on metal) can result in unclear or inaccurate marks. Different materials require specific marking tools, such as pencils for paper and boards and marking knives for wood.

      Teacher tip

      Recall measuring skills using a metal rule, revist using mm and being able to identify specific measurements on the rulers.

      Equipment

      pencils, rulers, set squares, protractors, masking tape, drawing curves, french curves, string, compass, tape measure, try squares, cutting mats, materials for marking.
