TOPIC 1: MAP WORK
MAP CALCULATIONS CAPS CONTENT
Learners must be able to do the following calculation:
Distance
•
• Area
• Gradient
• Vertical exaggeration
• Magnetic bearing
• Speed time and distance
WEIGHTING AND TIME
Mapwork should be taught on a continuous base and should be
integrated with theory. At least one period per week should be spent on
mapwork (about 40 minutes).
METHODOLOGY
Ensure that learner bring their mapwork equipment to school in order to
practice the calculation skills regularly. Do not assume that learners
know how to use a ruler, protractor and calculator. Show them properly
how to measure correctly and emphasise that accuracy is of utmost
importance. Teach them the measurement rules related to mapwork as
you explain and let them practice.
Group work can be very effective when teaching mapwork. Extract your
strongest candidate and teach an extra lesson on what you want to
teach to the rest of the class to them. Use these learners in class as
group leader of groups of not more than four to ensure all learners can
practically do what you explain systematically in class. This does not
imply that they must do all the teaching. The teacher should
demonstrate and explain and each group should then work on two
2|Page GRADE12GEOGRAPHYMAPWORK
, examples together, before each learner must do an example on their
own to gain confidence.
ADDITIONAL NOTES
The table below is a short summary of how to measure and do calculations.
