Think some more about the special place that will be the basis of your Unit 1 Project. Do you see places where you will use metric measures and other places where you will use imperial measures? How will you decide?
Go to the navigation tree and view the Unit 1 Project to review the initial requirements of the project. Please make a few notes and store them in your course folder.
In Lesson 2 you will be ready to represent your place visually using simple shapes such as cylinders, cones, rectangular solids, and spheres. You will also calculate the volumes and surface areas of these solids using both imperial and metric units.
Going Beyond
Did You Know?
The Romans used milestones to mark every 1000 steps.
There are other units of measure based on referents. Such units have their origins in agriculture and navigation, for example. Use your favourite Internet search engine to extend your learning by researching the origins of such units of measure as bolt, furlong, league, milestone, and chain. In your search, identify the imperial and metric equivalents of these measures, as well as the referents that are associated with these measures, and explain why these particular referents were chosen.
