Lesson notes

Learning Objectives

Indicator: 1.3.1.LI.1 - Understand standard units of measurement for work pieces.

By the end of the lesson, learners can:

Recall the common standard units of linear measurement (millimetre, centimetre, metre) and angular measurement (degrees, minutes, seconds) used for work pieces.
Convert between common metric units of measurement (e.g., millimetres to centimetres, centimetres to metres) with accuracy.
Explain the importance of using standard units of measurement in the manufacturing industry for uniformity, quality, and accuracy.
Identify the appropriate standard unit for measuring a given work piece based on its size and nature.
Apply standard units correctly when recording dimensions of a work piece during a practical measuring task.

This lesson builds on the datum setting and coordinate systems covered in Week 3 and the marking out work from Week 4. It prepares learners for Week 7, where they will use gauges to measure work pieces.

Exemplars (from the NaCCA curriculum)

Collaborative Learning: Learners in mixed-ability groups read from the library and Internet on the standard units of measurement for work pieces, present their results to the class and receive feedback.
Talk for Learning: In pairs, learners discuss and share the importance of using standard measurements (such as linear and angular measurements) in the manufacturing industry e.g., for uniformity, quality, and accuracy.
