This topic teaches you to sort activities into three sectors, then use that sorting to explain value, location and employment. It is one branch of economic activities and resources.
What does this topic cover?
The four lessons build on each other, and each trains a skill that SPM data questions test.
- Classifying an activity by what it does gives the sorting rule.
- Tracing value added shows how worth grows along a chain.
- Explaining location from several factors links an activity to where it sits.
- Comparing two sectors checks that measures match before you compare.
How do the parts connect?
Classification comes first, because every other skill needs it. You cannot trace value added until you know which step is primary, secondary or tertiary.
Location and comparison then use that sorting. A sawmill sits near timber because it is secondary and needs raw material, whereas a shop sits near customers because it is tertiary.
One orienting example
This is a worked example. A bakery buys flour, bakes bread and sells it at a counter.
The farm that grew the wheat is primary. Baking the bread is secondary, because it turns flour into bread. Serving a customer is tertiary, because it is a service. One business has three sectors, so the company label cannot decide the sector.
Who should start where?
A student new to Form 4 should begin with the classification lesson and finish it before anything else. A student who classifies well but loses marks on data should go to the value-added and comparison lessons.
If you want to test yourself first, try the topic practice set and see which questions fail. The map and graph reading practice gives extra data to read.
