Glossary Terms

In this course you will often come across math-related words that may be unfamiliar to you. These words will likely be used over and over again, so it is important that you understand the meaning of these words. You will also need to record the words and their meanings so that you can refer to them when necessary.

In this course you will create your own glossary. Use the document titled Glossary Terms as a guide for how to design your own Glossary terms to keep a record of the math terms that you come across in Mathematics 10C.

In this lesson the suggested glossary terms you should add to Glossary Terms include the following:

  • imperial measurement
  • referent
  • SI measurement

Read

Foundations and Pre-calculus Mathematics 10 (Pearson)

Read “Make Connections” on page 4. Pay particular attention to the following:

  • units used in the imperial system
  • when the SI system of measures gained popularity among the countries of the world, including Canada
  • what common measurement is still often reported in imperial units

Read page 6 to find out how imperial units are related to each other. Try to find out from your reading what the differences are between the precision of an imperial measurement device compared to an SI measurement device. You will investigate measurement tools and conversions in Lessons 2 and 3.

A non-standard measurement unit is a unit that you would not normally use to report a measurement. Non-standard units are not found on measuring devices. For example, at one time the height of a horse was measured in hands. Personal referents, such as the ones you developed in the Math Lab, are examples of non-standard measurement units. Referents help you to estimate lengths in standard units. For example, you may know that the length of your foot is 25 cm. If you determine that the width of the hallway is as long as eight of your feet, then you can estimate that the hallway is 8 × 25 cm = 200 cm, or 2-m wide.
